Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

backend nodebb host = 127001 your nodebb hostport = 4567 your nodebb port

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Frequently Asked Questions

If you experience difficulties setting up a NodeBB instance perhaps one of the following may help

How do I startstoprestart NodeBB

You can call the nodebb executable to start and stop NodeBB

$ nodebbWelcome to NodeBBUsage nodebb start|stop|reload|restart|log|setup|reset|upgrade|dev|watch

start Start the NodeBB serverstop Stops the NodeBB serverreload Restarts NodeBBrestart Restarts NodeBBlog Opens the logging interface (useful for debugging)setup Runs the NodeBB setup scriptreset Disables all plugins restores the default themeupgrade Run NodeBB upgrade scripts ensure packages are up-to-datedev Start NodeBB in interactive development modewatch Start NodeBB in development mode and watch for changes

How do I upgrade my NodeBB

Please consult Upgrading NodeBB

67

NodeBB Documentation Release 041

I upgraded NodeBB and now X isnrsquot working properly

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

CHAPTER 4

Cp nht NodeBB

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Frequently Asked Questions

If you experience difficulties setting up a NodeBB instance perhaps one of the following may help

How do I startstoprestart NodeBB

You can call the nodebb executable to start and stop NodeBB

$ nodebbWelcome to NodeBBUsage nodebb start|stop|reload|restart|log|setup|reset|upgrade|dev|watch

start Start the NodeBB serverstop Stops the NodeBB serverreload Restarts NodeBBrestart Restarts NodeBBlog Opens the logging interface (useful for debugging)setup Runs the NodeBB setup scriptreset Disables all plugins restores the default themeupgrade Run NodeBB upgrade scripts ensure packages are up-to-datedev Start NodeBB in interactive development modewatch Start NodeBB in development mode and watch for changes

How do I upgrade my NodeBB

Please consult Upgrading NodeBB

67

NodeBB Documentation Release 041

I upgraded NodeBB and now X isnrsquot working properly

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

CHAPTER 2

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

backend nodebb host = 127001 your nodebb hostport = 4567 your nodebb port

sub vcl_recv

Pipe websocket connections directly to Nodejsif (reqhttpUpgrade ~ (i)websocket) set reqbackend = nodebbreturn (pipe)

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

CHAPTER 4

Cp nht NodeBB

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

For further impression take a look at the default plugins

You should also take a look at the helper-functions within Settings in order to create your own plugins There are afew methods that take response to call the methods of other plugins when fittingly

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

67

NodeBB Documentation Release 041

I upgraded NodeBB and now X isnrsquot working properly

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

CHAPTER 2

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

For further impression take a look at the default plugins

You should also take a look at the helper-functions within Settings in order to create your own plugins There are afew methods that take response to call the methods of other plugins when fittingly

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

backend nodebb host = 127001 your nodebb hostport = 4567 your nodebb port

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Frequently Asked Questions

If you experience difficulties setting up a NodeBB instance perhaps one of the following may help

How do I startstoprestart NodeBB

You can call the nodebb executable to start and stop NodeBB

$ nodebbWelcome to NodeBBUsage nodebb start|stop|reload|restart|log|setup|reset|upgrade|dev|watch

start Start the NodeBB serverstop Stops the NodeBB serverreload Restarts NodeBBrestart Restarts NodeBBlog Opens the logging interface (useful for debugging)setup Runs the NodeBB setup scriptreset Disables all plugins restores the default themeupgrade Run NodeBB upgrade scripts ensure packages are up-to-datedev Start NodeBB in interactive development modewatch Start NodeBB in development mode and watch for changes

How do I upgrade my NodeBB

Please consult Upgrading NodeBB

67

NodeBB Documentation Release 041

I upgraded NodeBB and now X isnrsquot working properly

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

backend nodebb host = 127001 your nodebb hostport = 4567 your nodebb port

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

CHAPTER 4

Cp nht NodeBB

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Frequently Asked Questions

If you experience difficulties setting up a NodeBB instance perhaps one of the following may help

How do I startstoprestart NodeBB

You can call the nodebb executable to start and stop NodeBB

$ nodebbWelcome to NodeBBUsage nodebb start|stop|reload|restart|log|setup|reset|upgrade|dev|watch

start Start the NodeBB serverstop Stops the NodeBB serverreload Restarts NodeBBrestart Restarts NodeBBlog Opens the logging interface (useful for debugging)setup Runs the NodeBB setup scriptreset Disables all plugins restores the default themeupgrade Run NodeBB upgrade scripts ensure packages are up-to-datedev Start NodeBB in interactive development modewatch Start NodeBB in development mode and watch for changes

How do I upgrade my NodeBB

Please consult Upgrading NodeBB

67

NodeBB Documentation Release 041

I upgraded NodeBB and now X isnrsquot working properly

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

CHAPTER 2

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

backend nodebb host = 127001 your nodebb hostport = 4567 your nodebb port

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

CHAPTER 4

Cp nht NodeBB

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

NodeBB Style Guide

For the most part NodeBB follows the Google Javascript Style Guide

Code Formatting

Ghi chuacute The existing codebase as of July 2013 does not adhere to this style guide 100 If you see instances wherethe style guide is not adhered to feel free to restyle and send off a pull request

Indentation amp Bracing

NodeBB uses tabbed indentation Bracing should follow the One True Brace Style

if (condition) code here

else otherwise

Put conditionals and statements on separate lines and wrap with curly braces even if itrsquos just one line

if (leTired) haveANap()

Errors

Most callbacks return an error as the first parameter Handle this error first before processing further

someFunction(parameters function(err data) if(err)

return callback(err) or handle error proceed as usual

)

Variables

Variables should always be prefaced with the var keyword

var foo = bar

Multiple declarations are to be included in the same var statement

var foo = barbar = baz

Semicolons

Use semicolons if at all possible

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Frequently Asked Questions

If you experience difficulties setting up a NodeBB instance perhaps one of the following may help

How do I startstoprestart NodeBB

You can call the nodebb executable to start and stop NodeBB

$ nodebbWelcome to NodeBBUsage nodebb start|stop|reload|restart|log|setup|reset|upgrade|dev|watch

start Start the NodeBB serverstop Stops the NodeBB serverreload Restarts NodeBBrestart Restarts NodeBBlog Opens the logging interface (useful for debugging)setup Runs the NodeBB setup scriptreset Disables all plugins restores the default themeupgrade Run NodeBB upgrade scripts ensure packages are up-to-datedev Start NodeBB in interactive development modewatch Start NodeBB in development mode and watch for changes

How do I upgrade my NodeBB

Please consult Upgrading NodeBB

67

NodeBB Documentation Release 041

I upgraded NodeBB and now X isnrsquot working properly

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

CHAPTER 4

Cp nht NodeBB

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Frequently Asked Questions

If you experience difficulties setting up a NodeBB instance perhaps one of the following may help

How do I startstoprestart NodeBB

You can call the nodebb executable to start and stop NodeBB

$ nodebbWelcome to NodeBBUsage nodebb start|stop|reload|restart|log|setup|reset|upgrade|dev|watch

start Start the NodeBB serverstop Stops the NodeBB serverreload Restarts NodeBBrestart Restarts NodeBBlog Opens the logging interface (useful for debugging)setup Runs the NodeBB setup scriptreset Disables all plugins restores the default themeupgrade Run NodeBB upgrade scripts ensure packages are up-to-datedev Start NodeBB in interactive development modewatch Start NodeBB in development mode and watch for changes

How do I upgrade my NodeBB

Please consult Upgrading NodeBB

67

NodeBB Documentation Release 041

I upgraded NodeBB and now X isnrsquot working properly

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

backend nodebb host = 127001 your nodebb hostport = 4567 your nodebb port

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Cp nht NodeBB

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Frequently Asked Questions

If you experience difficulties setting up a NodeBB instance perhaps one of the following may help

How do I startstoprestart NodeBB

You can call the nodebb executable to start and stop NodeBB

$ nodebbWelcome to NodeBBUsage nodebb start|stop|reload|restart|log|setup|reset|upgrade|dev|watch

start Start the NodeBB serverstop Stops the NodeBB serverreload Restarts NodeBBrestart Restarts NodeBBlog Opens the logging interface (useful for debugging)setup Runs the NodeBB setup scriptreset Disables all plugins restores the default themeupgrade Run NodeBB upgrade scripts ensure packages are up-to-datedev Start NodeBB in interactive development modewatch Start NodeBB in development mode and watch for changes

How do I upgrade my NodeBB

Please consult Upgrading NodeBB

67

NodeBB Documentation Release 041

I upgraded NodeBB and now X isnrsquot working properly

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

CHAPTER 2

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyPass http1270014567ProxyPassReverse http1270014567

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

CHAPTER 4

Cp nht NodeBB

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Frequently Asked Questions

If you experience difficulties setting up a NodeBB instance perhaps one of the following may help

How do I startstoprestart NodeBB

How do I upgrade my NodeBB

Please consult Upgrading NodeBB

67

NodeBB Documentation Release 041

I upgraded NodeBB and now X isnrsquot working properly

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

backend nodebb host = 127001 your nodebb hostport = 4567 your nodebb port

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

NodeBB Documentation Release 041

I upgraded NodeBB and now X isnrsquot working properly

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Change the domain and dont use the secret in the example above

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

backend nodebb host = 127001 your nodebb hostport = 4567 your nodebb port

sub vcl_recv

Pipe websocket connections directly to Nodejsif (reqhttpUpgrade ~ (i)websocket) set reqbackend = nodebbreturn (pipe)

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

For further impression take a look at the default plugins

You should also take a look at the helper-functions within Settings in order to create your own plugins There are afew methods that take response to call the methods of other plugins when fittingly

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

backend nodebb host = 127001 your nodebb hostport = 4567 your nodebb port

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

CHAPTER 4

Cp nht NodeBB

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Cu higravenh NodeBB

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

Ghi chuacute If you would like to write your own database driver for NodeBB please visit our community forum and wecan point you in the right direction

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ProxyPass http1270014567ProxyPassReverse http1270014567

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

For further impression take a look at the default plugins

You should also take a look at the helper-functions within Settings in order to create your own plugins There are afew methods that take response to call the methods of other plugins when fittingly

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Please consult Upgrading NodeBB

I installed an incompatible plugin and now my forum wonrsquot start

If you know which plugin caused problems disable it by running nodebb resetplugin=nodebb-plugin-pluginName

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Configuring Databases

NodeBB has a Database Abstraction Layer (DBAL) that allows one to write drivers for their database of choiceCurrently we have the following options

MongoDB

If yoursquore afraid of running out of memory by using Redis or want your forum to be more easily scalable you caninstall NodeBB with MongoDB This tutorial assumes you know how to SSH into your server and have root access

These instructions are for Ubuntu Adjust them accordingly for your distro

Note If you have to add sudo to any command do so No one is going to hold it against you )

Step 1 Install MongoDB

The latest and greatest MongoDB is required (or at least greater than the package manager) The instructions to installit can be found on the MongoDB manual)

Step 2 Install nodejs

Like MongoDB the latest and greatest nodejs is required (or at least greater than the package manager) so Irsquom leavingthis to the official wiki The instructions to install can be found on Joyent

Note NPM is installed along with nodejs so there is no need to install it separately

Step 3 Install the Base Software Stack

Enter the following into the terminal to install the base software required to run NodeBB

17

NodeBB Documentation Release 041

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

18 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Configuring Varnish Cache

To be sure Varnish will work properly with NodeBB check that your configuration etcvarnishdefaultvclis optimized for websockets

backend nodebb host = 127001 your nodebb hostport = 4567 your nodebb port

sub vcl_recv

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Important This list is by no means exhaustive Hooks are added on an as-needed basis (or if we can see a potentialuse case ahead of time) and all requests to add new hooks to NodeBB should be sent to us via the issue tracker

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Otherwise disable all plugins by running nodebb reset plugins

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

apt-get install git build-essential imagemagick

Step 4 Clone the Repository

Enter the following into the terminal replacing pathtonodebbinstalllocation to where you would like NodeBB tobe installed

$ cd pathtonodebbinstalllocation$ git clone gitgithubcomNodeBBNodeBBgit nodebb

Step 5 Install The Required NodeBB Dependencies

Go into the newly created nodebb directory and install the required dependencies by entering the following

$ cd nodebb$ npm install

Step 6 Adding a New Database With Users

To go into the MongoDB command line type

$ mongo

To add a new database called nodebb type

gt use nodebb

To add a user to access the nodebb database type

For MongoDB 26x

gt dbcreateUser( user nodebb pwd ltEnter in a secure passwordgt roles [rarr˓readWrite ] )

Note NodeBB requires MongoDB 260 or higher The role readWrite provides read or write any collection withina specific database to user

Step 7 Configure MongoDB

Modify etcmongodbconf

nano etcmongodbconf

To enable authentication uncomment auth = true Restart MongoDB

service mongodb restart

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

server listen 80

server_name forumexampleorg

location proxy_set_header X-Real-IP $remote_addrproxy_set_header X-Forwarded-For $proxy_add_x_forwarded_forproxy_set_header Host $http_hostproxy_set_header X-NginX-Proxy true

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

Writing the plugin library

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson

Step 8 Configuring NodeBB

Make sure you are in your NodeBB root folder If not just type

$ cd pathtonodebb

To setup the app type

$ node app --setup

bull Change the hostname to your domain name

bull Accept the defaults by pressing enter until it asks you what database you want to use Type mongo in that field

bull Accept the default port unless you changed it in the previous steps

bull Change your username to nodebb unless you set it to another username

bull Enter in the password you made in step 5

bull Change the database to nodebb unless you named it something else

Continue with the installation following the instructions the installer provides you

Step 9 Starting the App

To start the app run

$ nodebb start

Now visit yourdomainoripcom4567 and your NodeBB installation should be running

NodeBB can also be started with helper programs such as supervisor or forever You can also use nginx as a reverseproxy)

LevelDB

Follow the installation instructions for your particular OS but feel free to omit the Redis installation

After cloning NodeBB ensure that you run

npm install levelup leveldown

Finally set up a directory to store your LevelDB database for example

mkdir varlevel

Run the NodeBB install select level when it prompts you for your database If you created the folder as above youcan leave the rest of the questions as default

bull Redis (default see installation guides)

bull Mongo

bull Level

21 Configuring Databases 19

NodeBB Documentation Release 041

Running a Secondary Database

Cnh baacuteo This option is experimental and should not be used on a production environment

Both databases must be flushed before beginning - there isnrsquot a mechanism yet that detects an existing installationon one database but not another Until fail-safersquos such as these are implemented this option is hidden under the--advanced setup flag

node app --setup --advanced

Consult the other database guides for instructions on how to set up each specific database Once you select a secondarydatabasersquos modules therersquos no turning back - until somebody writes an exporterimporter

Currently this setup is being tested with Redis as the primary store (sets lists and sorted sets because Redis is superfast with these) and Mongo as the hash store (post and user data because ideally we wouldnrsquot want this in RAM)

Configuring Web Server Proxies

Here a few options that you can use to proxy your NodeBB forum

Configuring nginx as a proxy

NodeBB by default runs on port 4567 meaning that builds are usually accessed using a port number in addition totheir hostname

httpexampleorg4567

In order to allow NodeBB to be served without a port nginx can be set up to proxy all requests to a particular hostname(or subdomain) to an upstream NodeBB build running on any port

Requirements

bull NGINX version v1313 or greater

ndash Package managers may not provide a new enough version To get the latest version compile it your-self or if on Ubuntu use the NGINX Stable or NGINX Development PPA builds if you are onDebian use DotDeb repository to get the latest version of Nginx

ndash To determine your nginx version execute nginx -V in a shell

Configuration

NGINX-served sites are contained in a server block This block of options goes in a specific place based on hownginx was installed and configured

bull pathtonginxsites-available ndash files here must be aliased to sites-enabled

bull pathtonginxconfdconf ndash filenames must end in conf

bull pathtonginxhttpdconf ndash if all else fails

Below is the basic nginx configuration for a NodeBB build running on port 4567

20 Chapter 2 Cu higravenh NodeBB

NodeBB Documentation Release 041

proxy_pass http1270014567proxy_redirect off

SocketIO Supportproxy_http_version 11proxy_set_header Upgrade $http_upgradeproxy_set_header Connection upgrade

Notes

bull Remember to also edit configjson and change use_port from true to false

bull nginx must be on version 14x to properly support websockets DebianUbuntu use 12 although it will workthere will be a reduction in functionality

bull The proxy_pass IP should be 127001 if your NodeBB is hosted on the same physical server as yournginx server Update the port to match your NodeBB if necessary

bull This config sets up your nginx server to listen to requests for forumexampleorg It doesnrsquot magicallyroute the internet to it though so you also have to update your DNS server to send requests for forumexampleorg to the machine with nginx on it

Configuring apache as a proxy

Prerequisites to making this work Apache 24x

What if Irsquom on 22x (DebianUbuntu)

you need to manually compile and add the module ldquomod_proxy_wstunnelrdquo to the Apache 22 branch If yoursquore runningUbuntu or Debian yoursquore likely on the 22 branch of code

The following guide will assist with that if yoursquore on Debian or Ubuntu This is what I used to backport themod_proxy_wstunnel module to the 22 code base of Apache

httpwwwamossmeuk201306apache-2-2-websocket-proxying-ubuntu-mod_proxy_wstunnel

NOTE On ubuntu if yoursquore missing the configure file

You need to first run buildconf After this is complete you will then be able to use configure

automake amp libtool package was needed too

22 Configuring Web Server Proxies 21

NodeBB Documentation Release 041

apt-get install automake libtool

Enable the necessary modules

1 sudo a2enmod proxy

2 sudo a2enmod proxy_http

3 sudo a2enmod proxy_wstunnel

Add the config to Apache

The next step is adding the configuration to your virtualhostconf file typically located in etcapache2sites-availableThe below configuration assumes yoursquove used 4567 (default) port for NobeBB installation It also assumes you havethe bind address set to 127001

ProxyRequests off

ltProxy gtOrder denyallowAllow from all

ltProxygtProxyPass socketio1websocket ws1270014567socketio1websocketProxyPassReverse socketio1websocket ws1270014567socketio1websocket

ProxyPass http1270014567ProxyPassReverse http1270014567

The last thing you need to be sure of is that the configjson in the NodeBB folder has use_port false Otherwise somefunctionality will not work properly

Example nodebbconfigjson

base_url httpwwwyoursitecomport 4567use_port falsesecret 55sb254c-62e3-4e23-9407-8655147562763bind_address 127001database redisredis

Running NodeBB

The preferred way to start and stop NodeBB is by invoking its executable

bull nodebb start Starts the NodeBB server

bull nodebb stop Stops the NodeBB server

bull Alternatively you may use npm start and npm stop to do the same

The methods listed below are alternatives to starting NodeBB via the executable

Simple Nodejs Process

To start NodeBB run it with node (some distributions use the executable nodejs please adjust accordingly)

$ cd pathtonodebbinstall$ node app

However bear in mind that crashes will cause the NodeBB process to halt bringing down your forum Consider someof the more reliable options below

Supervisor Process

Using the supervisor package you can have NodeBB restart itself if it crashes

$ npm install -g supervisor$ supervisor app

As supervisor by default continues to pipe output to stdout it is best suited to development builds

25

NodeBB Documentation Release 041

Forever Daemon

Another way to keep NodeBB up is to use the forever package via the command line interface which can monitorNodeBB and re-launch it if necessary

$ npm install -g forever$ forever start appjs

Cp nht NodeBB

Upgrading NodeBB

NodeBBrsquos periodic releases are located in the Releases These releases contain what is usually considered the mostbug-free code and is designed to be used on production-level instances of NodeBB

You can utilise git to install a specific version of NodeBB and upgrade periodically as new releases are made

To obtain the latest fixes and features you can also git clone the latest version directly from the repository(master branch) although its stability cannot be guaranteed Core developers will attempt to ensure that everycommit results in a working client even if individual features may not be 100 complete

As always the NodeBB team is not responsible for any misadventures loss of data data corruption or any otherbad things that may arise due to a botched upgrade - so please donrsquot forget to back up before beginning

Upgrade Path

NodeBBrsquos upgrade path is designed so that upgrading between versions is straightforward NodeBB will provideupgrade compatibility (via the --upgrade flag) between the latest version of a lower branch and the latest version ofthe higher branch For example if v022 is the latest version in the v02x branch you can switch to the v03xbranch and suffer no ill effects Upgrading from v020 to v03x is not supported and NodeBB will warn youwhen attempting to upgrade that you are not upgrading cleanly

Upgrading between patch revisions

eg v010 to v011

Patch revisions contain bugfixes and other minor changes Updating to the latest version of code for your specificversion branch is all that is usually required

Execute steps 1 through 3

27

NodeBB Documentation Release 041

Upgrading between minor revisions

eg v013 to v020

Minor revisions contain new features or substantial changes that are still backwards compatible They may alsocontain dependent packages that require upgrading and other features may be deprecated (but would ideally still besupported)

Execute steps 1 through 4

Upgrade Steps

Note After upgrading between revisions (ie v004 to v005) it may be necessary to run the following upgrade stepsto ensure that any data schema changes are properly upgraded as well

1 Shut down your forum

While it is possible to upgrade NodeBB while it is running it is definitely not recommended particularly if it is anactive forum

$ cd pathtonodebb$ nodebb stop

2 Back up your data

Ghi chuacute This section is incomplete please take care to back up your files properly

Backing up Redis

As with all upgrades the first step is to back up your data Nobody likes database corruptionmisplacement

All of the textual data stored in NodeBB is found in a rdb file On typical installs of Redis the main database isfound at varlibredisdumprdb

Store this file somewhere safe

Backing up MongoDB

To run a backup of your complete MongoDB you can simply run

mongodump

which will create a directory structure that can be restored with the mongorestore command

It is recommended that you first shut down your database On Debian Ubuntu itrsquos likely to be sudo service mongodbstop

28 Chapter 4 Cp nht NodeBB

NodeBB Documentation Release 041

Backing up LevelDB

As LevelDB is simply a collection of flat files just copy the database over to a safe location ex

cp -r pathtodb pathtobackups

Store this file somewhere safe

Avatars

Uploaded images (avatars) are stored in publicuploads Feel free to back up this folder too

cd pathtonodebbpublictar -czf ~nodebb_assetstargz uploads

3 Grab the latest and greatest code

Navigate to your NodeBB $ cd pathtonodebb

If you are upgrading from a lower branch to a higher branch switch branches as necessary Make sure you arecompletely up-to-date on your current branch

For example if upgrading from v032 to v043

$ git fetch Grab the latest code from the NodeBB Repository$ git checkout v04x Type this as-is Not v042 or v043 but v04x$ git merge originv04x

If not upgrading between branches just run the following command

$ git pull

This should retrieve the latest (and greatest) version of NodeBB from the repository

Alternatively download and extract the latest versioned copy of the code from the Releases Page Overwrite any filesas necessary This method is not supported

4 Run the NodeBB upgrade script

This script will install any missing dependencies upgrade any plugins or themes (if an upgrade is available) andmigrate the database if necessary

$ nodebb upgrade

Note nodebb upgrade is only available after v030 If you are running an earlier version run these instead

bull npm install

bull ls -d node_modulesnodebb | xargs -n1 basename | xargs npm update

bull node app --upgrade

6 Start up NodeBB amp Test

You should now be running the latest version of NodeBB

Writing Plugins for NodeBB

So you want to write a plugin for NodeBB thatrsquos fantastic There are a couple of things you need to know beforestarting that will help you out

Like WordPress NodeBBrsquos plugins are built on top of a hook system in NodeBB This system exposes parts ofNodeBB to plugin creators in a controlled way and allows them to alter content while it passes through or executecertain behaviours when triggered

See the full list of hooks for more information

Filters and Actions

There are two types of hooks filters and actions

Filters act on content and can be useful if you want to alter certain pieces of content as it passes through NodeBBFor example a filter may be used to alter posts so that any occurrences of ldquoapplerdquo gets changed to ldquoorangerdquo Likewisefilters may be used to beautify content (ie code filters) or remove offensive words (profanity filters)

Actions are executed at certain points of NodeBB and are useful if yoursquod like to do something after a certain triggerFor example an action hook can be used to notify an admin if a certain user has posted Other uses include analyticsrecording or automatic welcome posts on new user registration

When you are writing your plugin make sure a hook exists where yoursquod like something to happen If a hook isnrsquotpresent file an issue and wersquoll include it in the next version of NodeBB

Configuration

Each plugin package contains a configuration file called pluginjson Here is a sample

39

NodeBB Documentation Release 041

id my-pluginname My Awesome Plugindescription Your plugins descriptionurl Absolute URL to your plugin or a Github repositorylibrary my-pluginjsstaticDirs

images publicimagesless [

assetsstyleless]hooks [

hook filterpostsave method filter hook actionpostsave method emailme

]languages pathtolanguages

The id property is a unique name that identifies the plugin

The library property is a relative path to the library in your package It is automatically loaded by NodeBB (if theplugin is activated)

The staticDirs property is an object hash that maps out paths (relative to your pluginrsquos root) to a directory thatNodeBB will expose to the public at the route pluginsYOUR-PLUGIN-ID

bull eg The staticDirs hash in the sample configuration maps pathtoyourpluginpublicimages to pluginsmy-pluginimages

The less property contains an array of paths (relative to your pluginrsquos directory) that will be precompiled into theCSS served by NodeBB

The hooks property is an array containing objects that tell NodeBB which hooks are used by your plugin and whatmethod in your library to invoke when that hook is called Each object contains the following properties (those with a are required)

bull hook the name of the NodeBB hook

bull method the method called in your plugin

bull priority the relative priority of the method when it is eventually called (default 10)

The languages property is optional which allows you to set up your own internationalization for your plugin (ortheme) Set up a similar directory structure as core for example languageen_GBmypluginjson

The core of your plugin is your library file which gets automatically included by NodeBB if your plugin is activated

Each method you write into your library takes a certain number of arguments depending on how it is called

bull Filters send a single argument through to your method while asynchronous methods can also accept a callback

bull Actions send a number of arguments (the exact number depends how the hook is implemented) These argumentsare listed in the list of hooks

40 Chapter 7 H thng plugin

NodeBB Documentation Release 041

Example library method

If we were to write method that listened for the actionpostsave hook wersquod add the following line to thehooks portion of our pluginjson file

hook actionpostsave method myMethod

Our library would be written like so

var MyPlugin = myMethod function(postData)

do something with postData here

Using NodeBB libraries to enhance your plugin

Occasionally you may need to use NodeBBrsquos libraries For example to verify that a user exists you would need tocall the exists method in the User class To allow your plugin to access these NodeBB classes use moduleparentrequire

var User = moduleparentrequire(user)Userexists(foobar function(err exists)

)

Installing the plugin

In almost all cases your plugin should be published in npm and your packagersquos name should be prefixed ldquonodebb-plugin-rdquo This will allow users to install plugins directly into their instances by running npm install

When installed via npm your plugin must be prefixed with ldquonodebb-plugin-rdquo or else it will not be found by NodeBB

As of v005 ldquoinstallingrdquo a plugin by placing it in the plugins folder is still supported but keep in mind that thepackage id and its folder name must match exactly or else NodeBB will not be able to load the plugin This featuremay be deprecated in later versions of NodeBB

Testing

Run NodeBB in development mode

nodebb dev

This will expose the plugin debug logs allowing you to see if your plugin is loaded and its hooks registered Activateyour plugin from the administration panel and test it out

Disabling Plugins

You can disable plugins from the ACP but if your forum is crashing due to a broken plugin you can reset all pluginsby executing

71 Writing Plugins for NodeBB 41

NodeBB Documentation Release 041

nodebb reset plugins

Alternatively you can disable one plugin by running

nodebb reset plugin=nodebb-plugin-im-broken

Available Hooks

The following is a list of all hooks present in NodeBB This list is intended to guide developers who are looking towrite plugins for NodeBB For more information please consult Writing Plugins for NodeBB

There are two types of hooks filters and actions Filters take an input (provided as a single argument) parse itin some way and return the changed value Actions take multiple inputs and execute actions based on the inputsreceived Actions do not return anything

Settings Framework

If you want to make your plugin customizable you may use the Settings Framework NodeBB offers

Server-Side Access

First you need some default settings just create a new object for this

73 Settings Framework 47

NodeBB Documentation Release 041

var defaultSettings = booleans

someBool truemoreBools [false false true]

strings

someString hello worldmultiLineString somenlongntextarrayOfStrings [somenlongntexts and another one]

numbers

multiArrayDimensions [[4242][2121]]multiArrayDimensions2 [[4242][]]justSomeNumbers []oneNumber 3anotherNumber 2

someKeys [C+S+13] Ctrl+Shift+Enter

Now you can use the server-side settings-module to access the saved settings like this

var Settings = moduleparentrequire(settings)var mySettings = new Settings(myPlugin 01 defaultSettings function()

the settings are ready and can accessedconsolelog(mySettings === this) trueconsolelog(thisget(stringssomeString) === mySettingsget()strings

rarr˓someString) true)

The second parameter should change at least every time the structure of default settings changes Because of this itrsquosrecommended to use your plugins version

To use the settings client-side you need to create a WebSocket that delivers the result of mySettingsget()

The mySettings-object will cache the settings so be sure to use methods like mySettingssync(callback)when the settings got changed from somewhere else and mySettingspersist(callback) when you finishedmySettingsset(key value) calls

You need to create a socket-listener like following to allow the admin to initiate a synchronization with the settingsstored within database

var SocketAdmin = moduleparentrequire(socketioadmin)SocketAdminsettingssyncMyPlugin = function()

mySettingssync()

If you want to add a reset-functionality you need to create another socket-listener

SocketAdminsettingsgetMyPluginDefaults = function (socket data callback) callback(null mySettingscreateDefaultWrapper())

The methods of the mySettings object you probably want to use

bull constructor()

bull sync([callback]) Reloads the settings from database overrides local changes

bull persist([callback]) Saves the local changes within database

48 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull get([key]) Returns the setting(s) identified by given key If no key is provided the whole settings-objectgets returned If no such setting is saved the default value gets returned

bull set([key ]value) Sets the setting of given key to given value Remember that itrsquos just a local changeyou need to call persist in order to save the changes

bull reset([callback]) Persists the default settings

bull getWrapper() Returns the local object as it would get saved within database

bull createWrapper(version settings) Creates an object like it would get saved within database con-taining given information and settings

bull createDefaultWrapper() Creates an object like it would get saved within database containing the de-fault settings

Client-Side Access

The next step is making the settings available to the admin

You need to use the hooks filteradminheaderbuild (to display a link to your page within ACP) andactionappload (to create the needed route)

Within your page you can access the client-side Settings API via

require([settings] function (settings) var wrapper = $(my_form_id) [1]settingssync(myPlugin wrapper) [2]

)

To make a button with the id save actually save the settings you can add the following at [2]

$(save)click(function(event) eventpreventDefault()settingspersist(myPlugin wrapper function()

socketemit(adminsettingssyncMyPlugin))

)

As said before the server-side settings-object caches the settings so we emit a WebSocket to notify the server tosynchronize the settings after they got persisted

To use a reset-button you can add the following at [2]

$(reset)click(function(event) eventpreventDefault()socketemit(adminsettingsgetMyPluginDefaults null function (err data)

settingsset(myPlugin data wrapper function()socketemit(adminsettingssyncMyPlugin)

))

)

There you go the basic structure is done Now you need to add the form-fields

Each field needs an attribute data-key to reference its position within the settings The Framework does supportany fields whose jQuery-object provides the value via the val() method

73 Settings Framework 49

NodeBB Documentation Release 041

The plugin to use for a field gets determined by its data-type type or tag-name in this order

Additionally the following plugins are registered by default

bull array (types div array) An Array of any other fields Uses the object within data-attributes todefine the array-elements Uses data-new to define the value of new created elements

bull key (types key) A field to input keyboard-combinations

bull checkbox number select textarea Handle appropriate fields

A full list of all attributes that may influence the behavior of the default Framework

bull data-key the key to saveload the value within configuration-object

bull data-type highest priority type-definition to determine what kind of element it is or which plugin to associate

bull type normal priority type-definition

bull data-empty if false or 0 then values that are assumed as empty turn into null data-empty of arrays affecttheir child-elements

bull data-trim if not false or 0 then values will get trimmed as defined by the elements type

bull data-split if set and the element doesnrsquot belong to any plugin itrsquos value will get split and joined by its value intothe field

bull array-elements

ndash data-split separator (HTML allowed) between the elements defaults to

ndash data-new value to insert into new created elements

ndash data-attributes an object to set the attributes of the child HTML-elements tagName as special keywill set the tag-name of the child HTML-elements

bull key-fields

ndash data-trim if false or 0 then the value will get saved as string else as object providing followingproperties ctrl alt shift meta code char

ndash data-split separator between different modifiers and the key-code of the value that gets saved (onlytakes effect if trimming)

ndash data-short if not false or 0 then modifier-keys get saved as first uppercase character (only takeseffect if trimming)

bull select

ndash data-options an array of objects containing text and value attributes

The methods of the settings module

bull registerPlugin(plugin[ types]) Registers the given plugin and associates it to the given types ifany otherwise the plugins default types will get used

bull get() Returns the saved object

bull set(hash settings[ wrapper[ callback[ notify]]]) Refills the fields with given set-tings and persists them hash Identifies your plugins settings settings The object to save in database(settings-wrapper if you use server-side Settings Framework) wrapper (default lsquoformrsquo) The DOM-Element that contains all fields to fill callback (default null) Gets called when done notify (de-fault true) Whether to display saved- and fail-notifications

bull sync(hash[ wrapper[ callback]]) Resets the settings to saved ones and refills the fields

50 Chapter 7 H thng plugin

NodeBB Documentation Release 041

bull persist(hash[ wrapper[ callback[ notify]]]) Reads the settings from given wrapper(default lsquoformrsquo) and saves them within database

For Settings 20 support the methods load and save are still available but not recommended

Custom Settings-Elements

If you want do define your own element-structure you can create a plugin for the Settings Framework

This allows you to use a whole object like a single field which - besides comfort in using multiple similar objects -allows you to use them within arrays

A plugin is basically an object that contains at least an attribute types that contains an array of strings that associateDOM-elements with your plugin

You can add a plugin at [1] using the method settingsregisterPlugin

To customize the way the associated fields get interpreted you may add the following methods to your plugin-object

All given elements are instances of JQuery

All methods get called within Settings-scope

bull use() Gets called when the plugin gets registered

bull [HTML-Element|JQuery] create(type tagName data) Gets called when a new elementshould get created (eg by expansion of an array)

bull destruct(element) Gets called when the given element got removed from DOM (eg by array-splice)

bull init(element) Gets called when an element should get initialized (eg after creation)

bull [value] get(element trim empty) Gets called whenever the value of the given element is re-quested trim Whether the result should get trimmed empty Whether considered as empty valuesshould get saved too

bull set(element value trim) Gets called whenever the value of the given element should be set togiven one trim Whether the value is assumed as trimmed

Writing Widgets for NodeBB

See the original blog post for a high level overview and screenshots of the widget system

Embedding HTML and JavaScript

You donrsquot need to be a developer to figure this out Head over to the Themes control panel and click on the Widgetstab Create a new HTML widget by dragging and dropping the widget onto whatever template you want

Copy and paste HTML or JavaScript into the widget and hit save - yoursquore done

You can optionally give your widget a container by dragging and dropping from the containers section onto yourselected widget

If yoursquore looking for some sample scripts head over to our plugins section and look for any topic labellednodebb-script-xyz Donrsquot forget to submit your scripts and ideas as well

Creating Widgets

You can define widgets in both plugins and themes If yoursquore building a plugin which simply delivers a widget(or collection of widgets) we strongly suggest you follow the nodebb-widget-xyz nomenclature instead whenpublishing

Registering your widget

Listen to this hook to register your widget

hook filterwidgetsgetWidgets method defineWidgets callbacked true

55

NodeBB Documentation Release 041

Pass this back in the array

Content defines the form that is displayed to customize your widget in the admin panel

Listening to your widget

NodeBB core will call your widget on the appropriate page load by way of the hooks system Thehook will be named after your widgetrsquos namespace (see previous example) - like so filterwidgetrenderwidget_namespace

This will pass in an object with the following useful properties

bull objarea - will have location template url

bull objdata - will have your admin-defined data in the example from the previous section you will be exposedan objdatamyKey

Defining Widget Areas in Themes

A Widget Area is characterized by a template and a location Themes can share widgets if they define the same WidgetAreas If an admin switches themes widgets that were previously defined in a Widget Area incompatible with the newtheme are saved

Listen to this hook to register your Widget Area

hook filterwidgetsgetAreas method defineWidgetAreas callbacked true

Pass this back in the array

name Category Sidebartemplate categorytpllocation sidebar

And thatrsquos all You can define as many Widget Areas in your theme as you wish If yoursquore still stuck have a look atthis commit which upgraded the Cerulean theme to use the widget system

Creating a new NodeBB Theme

NodeBB is built on Twitter Bootstrap which makes theming incredibly simple

Packaging for NodeBB

NodeBB expects any installed themes to be installed via npm Each individual theme is an npm package and userscan install themes through the command line ex

npm install nodebb-theme-modern-ui

The themersquos folder must contain at least two files for it to be a valid theme

1 themejson

2 themeless

themeless is where your themersquos styles will reside NodeBB expects LESS to be present in this file and willprecompile it down to CSS on-demand For more information regarding LESS take a look at the project homepage

Note A suggested organization for themeless is to import multiple smaller files instead of placing all of thestyles in the main themeless file

Configuration

The theme configuration file is a simple JSON string containing all appropriate meta data regarding the theme Pleasetake note of the following properties

bull id A unique id for a theme (eg ldquomy-themerdquo)

bull name A user-friendly name for the theme (eg ldquoMy Themerdquo)

57

NodeBB Documentation Release 041

bull description A onetwo line description about the theme (eg ldquoThis is the theme I made for my personalNodeBBrdquo)

bull screenshot A filename (in the same folder) that is a preview image (ideally 370x250 or an aspect ratio of1481)

bull url A fully qualified URL linking back to the themersquos homepageproject

bull templates (Optional) A system path (relative to your pluginrsquos root directory) to the folder containing tem-plate files If not specified NodeBB will search for the ldquotemplatesrdquo directory and then simply fall back to usingvanillarsquos template files

Child Themes

If your theme is based off of another theme simply modify your LESS files to point to the other theme as a base

topicless

As topicless from the theme nodebb-theme-vanilla was imported those styles are automatically incor-porated into your theme

Important If you depend on another theme make sure that your theme specifically states this in its packagejsonFor example for the above theme as we depend on nodebb-theme-vanilla we would explicitly state this byadding a new section into the packagejson file

peerDependencies nodebb-theme-vanilla ~001

Rendering Engine

How it works

Every page has an associated API call Template file and Language File

For example if you navigate to topic351nodebb-wiki the application will load three resources The API re-turn apitopic351nodebb-wiki and the template in this example ldquotopictplrdquo and the appropriate language fileldquotopicjsonrdquo

Just prepend api to the URLrsquos path name to discover the JSON return Any value in that return can be utilized in yourtemplate

A pagersquos name corresponds to the template and languagersquos filename (ex httpdomaincomtopicxyzcorrelates to topictpl) Sometimes this is not the case - ex userxyz loads accounttpl Have a look atthe custom_mapping section in publictemplatesconfigjson for more details

Templating Basics

Using the API return as your guide you can utilize any of those values in your templatelogic Using the above APIcall as an example for anything in the root level of the return you can do something like

topic_name

58 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

To access values in objects

privilegesread

And finally you can loop through arrays and create blocks like so

lt-- BEGIN posts --gtpostscontentlt-- END posts --gt

The above will create X copies of the above block for each item in the posts array

Templating Logic

NodeBBrsquos templating system implements some basic logic Using the same API call as above for our example Youcan write IF conditionals like so

lt-- IF unreplied --gtThis thread is unrepliedlt-- ENDIF unreplied --gt

Another example

lt-- IF disableSocialButtons --gtltbuttongtShare on Facebookltbuttongtlt-- ELSE --gtSharing has been disabledlt-- ENDIF disableSocialButtons --gt

We can check for the length of an array like so

lt-- IF postslength --gtThere be some postslt-- ENDIF postslength --gt

While looping through an array we can check if our current index is the first or last like so

lt-- BEGIN posts --gtlt-- IF first --gtlth1gtMain Author postsusernamelth1gt

lt-- ENDIF first --gtpostscontentlt-- IF last --gtEnd of posts Click here to scroll to the top

lt-- ENDIF last --gtlt-- END posts --gt

For more advanced documentation have a look at the templatesjs repository

Exposing template variables to client-side JavaScript

There are two ways of letting our JS know about data from the server-side apart from WebSockets (TODO will becovered in a different article)

92 Rendering Engine 59

NodeBB Documentation Release 041

Via jQueryget

If we require data from a different page we can make a $get call to any other API call For example if we wantedto know more about a specific user we could make a call like so

$get(RELATIVE_PATH + apiuserpsychobunny function(user) consolelog(user)

)

See this API call in action httpcommunitynodebborgapiuserpsychobunny

Via Template Variables

In topictpl for example we can add a hidden input like so

ltinput type=hidden template-variable=pageCount value=pageCount gt

The template system will immediately parse all of these and expose them via the following method

ajaxifyvariablesget(pageCount)

This is the ideal method of letting JS know about important variables within the template

Internationalization

The template engine interfaces with the internationalization system as well We can embed variables into languagestrings Letrsquos use this API call as well as this language file as an example We can now do something like the following

[[registerhelpusername_restrictions minimumUsernameLengthrarr˓maximumUsernameLength]]

Which will translate this string

A unique username between 1 and 2 characters

to

A unique username between 2 and 16 characters

Advanced Topics

Dynamically requiring and rendering a template file from client-side JavaScript

The template engine lazy loads templates on an as-needed basis and caches them If your code requires a template orpartial on-demand then you can

ajaxifyloadTemplate(myTemplate function(myTemplate) var html = templatesparse(myTemplate myData)

)

You can also access the invidual blocks inside each template which is handy for doing things like (for example)rendering a new postrsquos ltligt and dynamically sticking it in an already loaded ltulgt

60 Chapter 9 Nn tng giao din

NodeBB Documentation Release 041

Some stuff herelt-- BEGIN posts --gtWe just want to pull this block onlylt-- END posts --gt some stuff here

ajaxifyloadTemplate(myTemplate function(myTemplate) var block = templatesgetBlock(myTemplate posts)var html = templatesparse(block myData)

)

Rendering templates on server-side Nodejs

The templating system hooks into Express just like most other templating frameworks Just use either apprenderor resrender to parse the appropriate template

resrender(myTemplate myData)

apprender(myTemplate myData function(err parsedTemplate) consolelog(parsedTemplate)

)

Is it possible to install NodeBB via FTP

It is possible to transfer the files to your remote server using FTP but you do require shell access to the server in orderto actually ldquostartrdquo NodeBB Here is a handy guide for installing NodeBB on DigitalOcean

Irsquom getting an ldquonpm ERRrdquo error

For the most part errors involving npm are due to Nodejs being outdated If you see an error similar to this one whilerunning npm install

npm ERR Unsupportednpm ERR Not compatible with your version of nodenpm connect2711

Yoursquoll need to update your Nodejs version to 08 or higher

To do this on Ubuntu

add-apt-repository ppachris-leanodejs apt-get update ampamp apt-get dist-upgrade -y

If successful running the following command should show a version higher than 08

apt-cache policy nodejs

URLs on my NodeBB (or emails) still have the port number in them

If you are using nginx or Apache as a reverse proxy you donrsquot need the port to be shown Simply run nodebb setupand specify the base URL without a port number

Alternatively edit the configjson file using your favourite text editor and change use_port to false

The ldquoRecently Logged In IPsrdquo section only shows 127001

NodeBBs running behind a proxy may have difficulties determining the original IP address that requests come fromIt is important that the proxy server provides the referral IP header

In nginx ensure that the following line is present in your server block

proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

In addition ensure that the use_port option is set to false in your NodeBBrsquos configjson
