.. Converse.js documentation master file, created by sphinx-quickstart on Fri Apr 26 20:48:03 2013. You can adapt this file completely to your liking, but it should at least contain the root `toctree` directive. .. toctree:: :maxdepth: 2 .. contents:: Table of Contents :depth: 3 :local: ========================================= Quickstart (to get a demo up and running) ========================================= When you download a specific release of *Converse.js* there will be two minified files inside the zip file. * builds/converse.min.js * css/converse.min.css You can include these two files inside the ** element of your website via the *script* and *link* tags: :: You need to initialize Converse.js with configuration settings according to your requirements. Please refer to the `Configuration variables`_ section further below for info on all the available configuration settings. To configure Converse.js, put the following inline Javascript code at the bottom of your page (after the closing ** element). :: require(['converse'], function (converse) { converse.initialize({ auto_list_rooms: false, auto_subscribe: false, bosh_service_url: 'https://bind.conversejs.org', // Please use this connection manager only for testing purposes hide_muc_server: false, i18n: locales.en, // Refer to ./locale/locales.js to see which locales are supported prebind: false, show_controlbox_by_default: true, roster_groups: true }); }); The `index.html `_ file inside the Converse.js repository may serve as a nice usable example. These minified files provide the same demo-like functionality as is available on the `conversejs.org `_ website. Useful for testing or demoing. You'll most likely want to implement some kind of single persistent session solution for your website, where users authenticate once in your website and then stay logged in to their XMPP session upon the next page reload. For more info on this, read: `Prebinding and Single Session Support`_. You might also want to have more fine-grained control of what gets included in the minified Javascript file. Read `Configuration`_ and `Minification`_ for more info on how to do that. ============ Introduction ============ Even though you can connect to public XMPP servers on the `conversejs.org`_ website, *Converse.js* is not really meant to be a "Software-as-a-service" (SaaS) webchat. Instead, its goal is to provide the means for website owners to add a tightly integrated instant messaging service to their own websites. As a website owner, you are expected to host *Converse.js* yourself, and to do some legwork to properly configure and integrate it into your site. The benefit in doing this, is that your users have a much more streamlined and integrated webchat experience and that you have control over the data. The latter being a requirement for many sites dealing with sensitive information. You'll need to set up your own XMPP server and in order to have `Session Support`_ (i.e. single-signon functionality whereby users are authenticated once and stay logged in to XMPP upon page reload) you will likely also have to add some server-side code. The `What you will need`_ section has more information on all these requirements. ======== Features ======== Off-the-record encryption ========================= Converse.js supports `Off-the-record (OTR) `_ encrypted messaging. The OTR protocol not only **encrypts your messages**, it provides ways to **verify the identity** of the person you are talking to, **plausible deniability** and **perfect forward secrecy** by generating new encryption keys for each conversation. In its current state, Javascript cryptography is fraught with dangers and challenges that make it impossible to reach the same standard of security that is available with native "desktop" software. This is due to its runtime malleability, the way it is "installed" (e.g. served) and the browser's lack of cryptographic primitives needed to implement secure crypto. For harsh but fairly valid criticism of Javascript cryptography, read: `Javascript Cryptography Considered Harmful `_. To get an idea on how this applies to OTR support in Converse.js, please read `my thoughts on it `_. For now, suffice to say that although its useful to have OTR support in Converse.js in order to avoid most eavesdroppers, if you need serious communications privacy, then you're much better off using native software. Sound Notifications =================== From version 0.8.1 Converse.js can play a sound notification when you receive a message. For more info, please see the `play_sounds`_ configuration setting. Multilingual Support ==================== Converse.js is translated into multiple languages. The default build, ``converse.min.js``, includes all languages. Languages increase the size of the Converse.js significantly. If you only need one, or a subset of the available languages, it's better to make a custom build which includes only those languages that you need. Chat Rooms ========== Commands -------- Here are the different commands that may be used in a chat room: +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | Event Type | When is it triggered? | Example (substitue $nickname with an actual user's nickname) | +============+==============================================================================================+===============================================================+ | **ban** | Ban a user from the chat room. They will not be able to join again. | /ban $nickname | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | **clear** | Clear the messages shown in the chat room. | /clear | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | **deop** | Make a moderator a normal participant. | /deop $nickname [$reason] | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | **help** | Show the list of available commands. | /help | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | **kick** | Kick a user out of a room. They will be able to join again. | /kick $nickname [$reason] | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | **me** | Speak in the 3rd person. | /me $message | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | **mute** | Remove a user's ability to post messages to the room. They will still be able to observe. | /mute $nickname [$reason] | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | **nick** | Change your nickname. | /nick $nickname | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | **op** | Make a normal participant a moderator. | /op $nickname [$reason] | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | **topic** | Set the topic of the chat room. | /topic ${topic text} | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ | **voice** | Allow a muted user to post messages to the room. | /voice $nickname [$reason] | +------------+----------------------------------------------------------------------------------------------+---------------------------------------------------------------+ ================== What you will need ================== An XMPP server ============== *Converse.js* implements `XMPP`_ as its messaging protocol, and therefore needs to connect to an XMPP/Jabber server (Jabber is really just a synonym for XMPP). You can connect to public XMPP servers like ``jabber.org`` but if you want to have `Session Support`_ you'll have to set up your own XMPP server. You can find a list of public XMPP servers/providers on `xmpp.net`_ and a list of servers that you can set up yourself on `xmpp.org`_. A BOSH Connection Manager ========================= Your website and *Converse.js* use `HTTP`_ as protocol to communicate with the webserver. HTTP connections are stateless and usually shortlived. `XMPP`_ on the other hand, is the protocol that enables instant messaging, and its connections are stateful and usually longer. To enable a web application like *Converse.js* to communicate with an XMPP server, we need a proxy in the middle that can act as a bridge between the two protocols. The `index.html `_ file inside the This is the job of a connection manager. A connection manager can be either a standalone application or part of an XMPP server. Popular XMPP servers such as `ejabberd `_, `prosody `_ and `openfire `_ all include their own connection managers (but you usually have to enable them in the configuration). Standalone connection managers also exist, see for example `Punjab `_. The demo on the `Converse.js homepage`_ uses a connection manager located at https://bind.conversejs.org. This connection manager is available for testing purposes only, please don't use it in production. Overcoming cross-domain request restrictions -------------------------------------------- Lets say your domain is *example.org*, but the domain of your connection manager is *example.com*. HTTP requests are made by *Converse.js* to the connection manager via XmlHttpRequests (XHR). Until recently, it was not possible to make such requests to a different domain than the one currently being served (to prevent XSS attacks). Luckily there is now a standard called `CORS`_ (Cross-origin resource sharing), which enables exactly that. Modern browsers support CORS, but there are problems with Internet Explorer < 10. IE 8 and 9 partially support CORS via a proprietary implementation called XDomainRequest. There is a `Strophe.js plugin`_ which you can use to enable support for XDomainRequest when it is present. In IE < 8, there is no support for CORS. Instead of using CORS, you can add a reverse proxy in Apache/Nginx which serves the connection manager under the same domain as your website. This will remove the need for any cross-domain XHR support. For example: ~~~~~~~~~~~~ Assuming your site is accessible on port ``80`` for the domain ``mysite.com`` and your connection manager manager is running at ``someothersite.com/http-bind``. The *bosh_service_url* value you want to give Converse.js to overcome the cross-domain restriction is ``mysite.com/http-bind`` and not ``someothersite.com/http-bind``. Your ``nginx`` or ``apache`` configuration will look as follows: Nginx ~~~~~ :: http { server { listen 80 server_name mysite.com; location ~ ^/http-bind/ { proxy_pass http://someothersite.com; } } } Apache ~~~~~~ :: ServerName mysite.com RewriteEngine On RewriteRule ^/http-bind(.*) http://someothersite.com/http-bind$1 [P,L] Server-side authentication ========================== .. _`Session Support`: Prebinding and Single Session Support ------------------------------------- It's possible to enable single-site login, whereby users already authenticated in your website will also automatically be logged in on the chat server, This session should also persist across page loads. In other words, we don't want the user to have to give their chat credentials every time they reload the page. To do this you will require a `BOSH server `_ for converse.js to connect to (see the `bosh_service_url`_ under `Configuration variables`_) as well as a BOSH client on your own server (written for example in Python, Ruby or PHP) that will do the pre-authentication before the web page loads. .. note:: A BOSH server acts as a bridge between HTTP, the protocol of the web, and XMPP, the instant messaging protocol. Converse.js can only communicate via HTTP, but we need to communicate with an XMPP server in order to chat. So the BOSH server acts as a middle man, translating our HTTP requests into XMPP stanzas and vice versa. Jack Moffitt has a great `blogpost`_ about this and even provides an `example Django application`_ to demonstrate it. When you authenticate to the XMPP server on your backend application (for example via a BOSH client in Django), you'll receive two tokens, RID (request ID) and SID (session ID). The **Session ID (SID)** is a unique identifier for the current *session*. This number stays constant for the entire session. The **Request ID (RID)** is a unique identifier for the current *request* (i.e. page load). Each page load is a new request which requires a new unique RID. The best way to achieve this is to simply increment the RID with each page load. When you initialize converse.js in your browser, you need to pass it these two tokens. Converse.js will then use them to attach to the session you just created. You can embed the RID and SID tokens in your HTML markup or you can do an XMLHttpRequest call to your server and ask it to return them for you. Below is one example of how this could work. An Ajax call is made to the relative URL **/prebind** and it expects to receive JSON data back. :: $.getJSON('/prebind', function (data) { converse.initialize({ prebind: true, bosh_service_url: data.bosh_service_url, jid: data.jid, sid: data.sid, rid: data.rid }); ); **Here's what's happening:** The JSON data returned from the Ajax call to example.com/prebind contains the user's JID (jabber ID), RID, SID and the URL to the BOSH server (also called a *connection manager*). These values are then passed to converse.js's ``initialize`` method. .. note:: If you want to enable single session support, you need to set **prebind: true** when calling **converse.initialize** (see ./index.html). Additionally you need to pass in valid **jid**, **sid**, **rid** and **bosh_service_url** values. Example code for server-side prebinding --------------------------------------- * PHP: See `xmpp-prebind-php `_ by Michael Weibel and the folks from Candy chat. * Python: See this `example Django application`_ by Jack Moffitt. =========== Development =========== If you want to work with the non-minified Javascript and CSS files you'll soon notice that there are references to a missing *components* folder. Please follow the instructions below to create this folder and fetch Converse's 3rd-party dependencies. .. note:: Users have reported that converse.js cannot be built on Windows. Patches to fix this are welcome. Install the development and front-end dependencies ================================================== We use development tools (`Grunt `_ and `Bower `_) which depend on Node.js and npm (the Node package manager). If you don't have Node.js installed, you can download and install the latest version `here `_. Also make sure you have ``git`` installed. `Details `_. Once you have *Node.js* and *git* installed, run the following command inside the Converse.js directory: :: make dev Or alternatively, if you don't have GNU Make: :: npm install bower update This will first install the Node.js development tools (like Grunt and Bower) and then use Bower to install all of Converse.js's front-end dependencies. The front-end dependencies are those javascript files on which Converse.js directly depends and which will be loaded in the browser. If you are curious to know what the different dependencies are: * Development dependencies: Take a look at whats under the *devDependencies* key in `package.json `_. * Front-end dependencies: See *dependencies* in `bower.json `_. .. note:: After running ```make dev```, you should now have a new directory *components*, which contains all the front-end dependencies of Converse.js. If this directory does NOT exist, something must have gone wrong. Double-check the output of ```make dev``` to see if there are any errors listed. For support, you can write to the mailing list: conversejs@librelist.com With AMD and require.js (recommended) ===================================== Converse.js uses `require.js `_ to asynchronously load dependencies. If you want to develop or customize converse.js, you'll want to load the non-minified javascript files. Add the following two lines to the ** section of your webpage: :: require.js will then let the main.js file be parsed (because of the *data-main* attribute on the *script* tag), which will in turn cause converse.js to be parsed. Without AMD and require.js ========================== Converse.js can also be used without require.js. If you for some reason prefer to use it this way, please refer to `non_amd.html `_ for an example of how and in what order all the Javascript files that converse.js depends on need to be loaded. Before submitting a pull request ================================ Add tests for your bugfix or feature ------------------------------------ Add a test for any bug fixed or feature added. We use Jasmine for testing. Take a look at ``tests.html`` and ``spec/MainSpec.js`` to see how the tests are implemented. If you are unsure how to write tests, please `contact me `_ and I'll be happy to help. Check that the tests pass ------------------------- Check that the Jasmine tests complete sucessfully. Open `tests.html `_ in your browser, and the tests will run automatically. On the command line you can run: :: grunt test Check your code for errors or bad habits by running JSHint ---------------------------------------------------------- `JSHint `_ will do a static analysis of your code and hightlight potential errors and/or bad habits. :: grunt jshint You can run both the tests and jshint in one go by calling: :: grunt check Developer API ============= .. note:: see also the `event api methods`_, not listed here. initialize ---------- Initializes converse.js. This method must always be called when using converse.js. The `initialize` method takes a map (also called a hash or dictionary) of `configuration variables`_. Example:: converse.initialize({ allow_otr: true, auto_list_rooms: false, auto_subscribe: false, bosh_service_url: 'https://bind.example.com', hide_muc_server: false, i18n: locales['en'], keepalive: true, play_sounds: true, prebind: false, show_controlbox_by_default: true, debug: false, roster_groups: true }); getBuddy -------- Returns a map of attributes for a given buddy (i.e. roster contact), specified by JID (Jabber ID). Example:: converse.getBuddy('buddy@example.com') The map of attributes: +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | Attribute | | +================+======================================================================================================================================+ | ask | If ask === 'subscribe', then we have asked this person to be our chat buddy. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | fullname | The person's full name. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | jid | The person's Jabber/XMPP username. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | requesting | If true, then this person is asking to be our chat buddy. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | subscription | The subscription state between the current user and this chat buddy. Can be `none`, `to`, `from` or `both`. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | id | A unique id, same as the jid. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | chat_status | The person's chat status. Can be `online`, `offline`, `busy`, `xa` (extended away) or `away`. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | user_id | The user id part of the JID (the part before the `@`). | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | resources | The known resources for this chat buddy. Each resource denotes a separate and connected chat client. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | groups | The roster groups in which this chat buddy was placed. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | status | Their human readable custom status message. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | image_type | The image's file type. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | image | The Base64 encoded image data. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | url | The buddy's website URL, as specified in their VCard data. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ | vcard_updated | When last the buddy's VCard was updated. | +----------------+--------------------------------------------------------------------------------------------------------------------------------------+ getRID ------ Returns the current RID (request ID) value. getSID ------ Returns the current SID (Session ID) value. Events ====== Converse.js emits events to which you can subscribe from your own Javascript. Concerning events, the following methods are available: Event API Methods ----------------- * **on(eventName, callback)**: Calling the ``on`` method allows you to subscribe to an event. Every time the event fires, the callback method specified by ``callback`` will be called. Parameters: * ``eventName`` is the event name as a string. * ``callback`` is the callback method to be called when the event is emitted. For example:: converse.on('message', function (messageXML) { ... }); * **once(eventName, callback)**: Calling the ``once`` method allows you to listen to an event exactly once. Parameters: * ``eventName`` is the event name as a string. * ``callback`` is the callback method to be called when the event is emitted. For example:: converse.once('message', function (messageXML) { ... }); * **off(eventName, callback)** To stop listening to an event, you can use the ``off`` method. Parameters: * ``eventName`` is the event name as a string. * ``callback`` refers to the function that is to be no longer executed. Event Types ----------- Here are the different events that are emitted: +--------------------------------+---------------------------------------------------------------------------------------------------+-----------------------------------------------------------------------------------------+ | Event Type | When is it triggered? | Example | +================================+===================================================================================================+=========================================================================================+ | **initialized** | Once converse.js has been initialized. | ``converse.on('initialized', function () { ... });`` | +--------------------------------+---------------------------------------------------------------------------------------------------+-----------------------------------------------------------------------------------------+ | **ready** | After connection has been established and converse.js has got all its ducks in a row. | ``converse.on('ready', function () { ... });`` | +--------------------------------+---------------------------------------------------------------------------------------------------+-----------------------------------------------------------------------------------------+ | **reconnect** | After the connection has dropped.

+--------------------------------+---------------------------------------------------------------------------------------------------+-----------------------------------------------------------------------------------------+ Minification ============ Minifying Javascript and CSS ---------------------------- Please make sure to read the section `Development`_ and that you have installed all development dependencies (long story short, you can run ``npm install`` and then ``grunt fetch``). We use `require.js`_ to keep track of *Converse.js* and its dependencies and to to bundle them together in a single minified file fit for deployment to a production site. To minify the Javascript and CSS, run the following command: :: grunt minify Javascript will be bundled and minified with `require.js`_'s optimization tool, using `almond `_. You can `read more about require.js's optimizer here`_. CSS is minified via `cssmin `_. Translations ============ .. note:: Translations take up a lot of space and will bloat your minified file. At the time of writing, all the translations add about 50KB of extra data to the minified javascript file. Therefore, make sure to only include those languages that you intend to support and remove from ./locale/locales.js those which you don't need. Remember to rebuild the minified file afterwards. The gettext POT file located in ./locale/converse.pot is the template containing all translations and from which for each language an individual PO file is generated. The POT file contains all translateable strings extracted from converse.js. To make a user facing string translateable, wrap it in the double underscore helper function like so: :: __('This string will be translated at runtime'); After adding the string, you'll need to regenerate the POT file, like so: :: make pot You can then create or update the PO file for a specific language by doing the following: :: msgmerge ./locale/de/LC_MESSAGES/converse.po ./locale/converse.pot -U To do this for ALL languages, run: :: make po The resulting PO file is then what gets translated. If you've created a new PO file, please make sure to add the following attributes at the top of the file (under *Content-Transfer-Encoding*). They are required as configuration settings for Jed, the Javascript translations library that we're using. :: "domain: converse\n" "lang: de\n" "plural_forms: nplurals=2; plural=(n != 1);\n" Unfortunately `Jed `_ cannot use the PO files directly. We have to generate from it a file in JSON format and then put that in a .js file for the specific language. To generate JSON from a PO file, you'll need po2json for node.js. Run the following command to install it (npm being the node.js package manager): :: npm install po2json You can then convert the translations into JSON format: :: po2json locale/de/LC_MESSAGES/converse.po locale/de/LC_MESSAGES/converse.json Now from converse.json paste the data as a value for the "locale_data" key in the object in the language's .js file. So, if you are for example translating into German (language code 'de'), you'll create or update the file ./locale/LC_MESSAGES/de.js with the following code: :: (function (root, factory) { define("de", ['jed'], function () { return factory(new Jed({ "domain": "converse", "locale_data": { // Paste the JSON data from converse.json here } }) } }(this, function (i18n) { return i18n; })); making sure to also paste the JSON data as value to the "locale_data" key. .. note:: If you are adding translations for a new language that is not already supported, you'll have to add the language path in main.js and make one more edit in ./locale/locales.js to make sure the language is loaded by require.js. Congratulations, you've now succesfully added your translations. Sorry for all those hoops you had to jump through. =============== Troubleshooting =============== Conflicts with other Javascript libraries ========================================= Problem: --------- You are using other Javascript libraries (like JQuery plugins), and get errors like these in your browser console:: Uncaught TypeError: Object [object Object] has no method 'xxx' from example.js Solution: --------- First, find out which object is referred to by ``Object [object Object]``. It will probably be the jQuery object ``$`` or perhaps the underscore.js object ``_``. For the purpose of demonstration, I'm going to assume its ``$``, but the same rules apply if its something else. The bundled and minified default build of converse.js, ``converse.min.js`` includes within it all of converse.js's dependencies, which include for example *jQuery*. If you are having conflicts where attributes or methods aren't available on the jQuery object, you are probably loading ``converse.min.js`` (which includes jQuery) as well as your own jQuery version separately. What then happens is that there are two ``$`` objects (one from converse.js and one from the jQuery version you included manually) and only one of them has been extended to have the methods or attributes you require. Which jQuery object you get depends on the order in which you load the libraries. There are multiple ways to solve this issue. Firstly, make sure whether you really need to include a separate version of jQuery. Chances are that you don't. If you can remove the separate version, your problem should be solved, as long as your libraries are loaded in the right order. Either case, whether you need to keep two versions or not, the solution depends on whether you'll use require.js to manage your libraries or whether you'll load them manually. With require.js ~~~~~~~~~~~~~~~ Instead of using ``converse.min.js``, manage all the libraries in your project (i.e. converse.js and its dependencies plus all other libraries you use) as one require.js project, making sure everything is loaded in the correct order. Then, before deployment, you make your own custom minified build that bundles everything you need. With
