|
<p>When you download a specific release of <em>Converse.js</em> there will be two minified files inside the zip file.</p>
|
|
<ul class="simple">
|
|
<li>converse.min.js</li>
|
|
<li>converse.min.css</li>
|
|
</ul>
|
|
<p>You can include these two files inside the <em><head></em> element of your website via the <em>script</em> and <em>link</em>
|
|
tags:</p>
|
|
<div class="highlight-python"><pre><link rel="stylesheet" type="text/css" media="screen" href="converse.min.css">
|
|
<script src="converse.min.js"></script></pre>
|
|
</div>
|
|
<p>Then, at the bottom of your page, after the closing <em></body></em> element, put the
|
|
following inline Javascript code:</p>
|
|
<div class="highlight-python"><pre>require(['converse'], function (converse) {
|
|
converse.initialize({
|
|
auto_list_rooms: false,
|
|
auto_subscribe: false,
|
|
bosh_service_url: 'https://bind.opkode.im', // 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,
|
|
xhr_user_search: false
|
|
});
|
|
});</pre>
|
|
</div>
|
|
<p>The <em>index.html</em> file inside the Converse.js folder serves as a nice usable
|
|
example of this.</p>
|
|
<p>These minified files provide the same demo-like functionality as is available
|
|
on the <a class="reference external" href="http://conversejs.org">conversejs.org</a> website. Useful for testing or demoing, but not very
|
|
practical.</p>
|
|
<p>You’ll most likely want to implement some kind of single-signon solution for
|
|
your website, where users authenticate once in your website and then stay
|
|
logged into their XMPP session upon page reload.</p>
|
|
<p>For more info on this, read: <a class="reference internal" href="#pre-binding-and-single-session-support">Pre-binding and Single Session Support</a>.</p>
|
|
<p>You might also want to have more fine-grained control of what gets included in
|
|
the minified Javascript file. Read <a class="reference internal" href="#configuration">Configuration</a> and <a class="reference internal" href="#minification">Minification</a> for more info on how to do
|
|
that.</p>

|
|
<p>Even though you can connect to public XMPP servers on the <a class="reference external" href="http://conversejs.org">conversejs.org</a>
|
|
website, <em>Converse.js</em> is not really meant to be a “Software-as-a-service” (SaaS)
|
|
webchat.</p>
|
|
<p>Instead, its goal is to provide the means for website owners to add a tightly
|
|
integrated instant messaging service to their own sites.</p>
|
|
<p>As a website owner, you are expected to host <em>Converse.js</em> yourself, and to do some legwork to
|
|
properly configure and integrate it into your site.</p>
|
|
<p>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.</p>
|
|
<p>You’ll need to set up your own XMPP server and in order to have
|
|
<a class="reference internal" href="#session-support">Session Support</a> (i.e. single-signon functionality whereby users are authenticated once and stay
|
|
logged in to XMPP upon page reload) you will also have to add some server-side
|
|
code.</p>
|
|
<p>The <a class="reference internal" href="#what-you-will-need">What you will need</a> section has more information on all these
|
|
requirements.</p>

<p><em>Converse.js</em> implements <a class="reference external" href="https://en.wikipedia.org/wiki/Xmpp">XMPP</a> as its messaging protocol, and therefore needs
|
|
to connect to an XMPP/Jabber server (Jabber is really just a synonym for XMPP).</p>
|
|
<p>You can connect to public XMPP servers like <tt class="docutils literal"><span class="pre">jabber.org</span></tt> but if you want to
|
|
have <a class="reference internal" href="#session-support">Session Support</a> you’ll have to set up your own XMPP server.</p>
|

<p>You can find a list of public XMPP servers/providers on <a class="reference external" href="http://xmpp.net">xmpp.net</a> and a list of
|

servers that you can set up yourself on <a class="reference external" href="http://xmpp.org/xmpp-software/servers/">xmpp.org</a>.</p>

|
|
<p>Your website and <em>Converse.js</em> use <a class="reference external" href="https://en.wikipedia.org/wiki/Hypertext_Transfer_Protocol">HTTP</a> as protocol to communicate with
|
|
the webserver. HTTP connections are stateless and usually shortlived.</p>
|
|
<p><a class="reference external" href="https://en.wikipedia.org/wiki/Xmpp">XMPP</a> on the other hand, is the protocol that enables instant messaging, and
|
|
its connections are stateful and usually longer.</p>
|
|
<p>To enable a web application like <em>Converse.js</em> to communicate with an XMPP
|
|
server, we need a proxy in the middle that can act as a bridge between the two
|
|
protocols.</p>
|
|
<p>This is the job of a connection manager. A connection manager can be either a
|
|
standalone application or part of an XMPP server. <a class="reference external" href="http://www.ejabberd.im">ejabberd</a> for example,
|
|
includes a connection manager (but you have to enable it).</p>
|
|
<p>The demo on the <a class="reference external" href="http://conversejs.org">Converse.js homepage</a> uses a a connection manager located at <a class="reference external" href="https://bind.opkode.im">https://bind.opkode.im</a>.
|
|
This connection manager is for testing purposes only, please don’t use it in
|
|
production.</p>
|
|
<div class="section" id="overcoming-cross-domain-request-restrictions">
|
|
<h3><a class="toc-backref" href="#id7">Overcoming cross-domain request restrictions</a><a class="headerlink" href="#overcoming-cross-domain-request-restrictions" title="Permalink to this headline">¶</a></h3>
|
|
<p>The domain of the <em>Converse.js</em> demo is <em>conversejs.org</em>, but the domain of the connection manager is <em>opkode.im</em>.
|
|
HTTP requests are made by <em>Converse.js</em> 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).</p>
|
|
<p>Luckily there is now a standard called <a class="reference external" href="https://en.wikipedia.org/wiki/Cross-origin_resource_sharing">CORS</a> (Cross-origin resource sharing), which enables exactly that.
|
|
Modern browsers support CORS, but there are problems with Internet Explorer <
|
|
10.</p>
|
|
<p>IE 8 and 9 partially support CORS via a proprietary implementation called
|
|
XDomainRequest. There is a <a class="reference external" href="https://gist.github.com/1095825/6b4517276f26b66b01fa97b0a78c01275fdc6ff2">Strophe.js plugin</a> which you can use to enable
|
|
support for XDomainRequest when it is present.</p>
|
|
<p>In IE < 8, there is no support for CORS.</p>
|
|
<p>If you need to support these browsers, you can add a front-end 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.</p>

<p>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,
|
|
but this will require custom code on your server.</p>
|
|
<p>Jack Moffitt has a great <a class="reference external" href="http://metajack.im/2008/10/03/getting-attached-to-strophe">blogpost</a> about this and even provides an <a class="reference external" href="https://github.com/metajack/strophejs/tree/master/examples/attach">example Django application</a> to demonstrate it.</p>

<div class="admonition note">
|
|
<p class="first admonition-title">Note</p>
|
|
<p class="last">If you want to enable single session support, make sure to pass <strong>prebind: true</strong>
|
|
when you call <strong>converse.initialize</strong> (see ./index.html).</p>
|
|
</div>
|
|
<p>When you authenticate to the XMPP server on your backend, you’ll receive two
|
|
tokens, RID (request ID) and SID (session ID).</p>
|
|
<p>These tokens then need to be passed back to the javascript running in your
|
|
browser, where you will need them attach to the existing session.</p>
|
|
<p>You can embed the RID and SID tokens in your HTML markup or you can do an
|
|
XMLHttpRequest call to you server and ask it to return them for you.</p>
|
|
<p>Below is one example of how this could work. An Ajax call is made to the
|
|
relative URL <strong>/prebind</strong> and it expects to receive JSON data back.</p>
|
|
<div class="highlight-python"><pre>$.getJSON('/prebind', function (data) {
|
|
var connection = new Strophe.Connection(converse.bosh_service_url);
|
|
connection.attach(data.jid, data.sid, data.rid, function (status) {
|
|
if ((status === Strophe.Status.ATTACHED) || (status === Strophe.Status.CONNECTED)) {
|
|
converse.onConnected(connection)
|
|
}
|
|
});
|
|
}
|
|
);</pre>
|
|
</div>
|
|
<p><strong>Here’s what’s happening:</strong></p>
|
|
<p>The JSON data contains the user’s JID (jabber ID), RID and SID. The URL to the
|
|
BOSH connection manager is already set as a configuration setting on the
|
|
<em>converse</em> object (see ./main.js), so we can reuse it from there.</p>
|
|
<p>A new Strophe.Connection object is instantiated and then <em>attach</em> is called with
|
|
the user’s JID, the necessary tokens and a callback function.</p>
|
|
<p>In the callback function, you call <em>converse.onConnected</em> together with the
|
|
connection object.</p>

<p>If you want to work with the non-minified Javascript and CSS files you’ll soon
|
|
notice that there are references to a missing <em>components</em> folder. Please
|

follow the instructions below to create this folder and fetch Converse’s

3rd-party dependencies.</p>

<p>We use development tools (<a class="reference external" href="http://gruntjs.com">Grunt</a> and <a class="reference external" href="http://bower.io">Bower</a>)
|
|
which depend on Node.js and npm (the Node package manager).</p>
|
|
<p>If you don’t have Node.js installed, you can download and install the latest
|
|
version <a class="reference external" href="https://nodejs.org/download">here</a>.</p>
|
|
<p>Once you have Node.js installed, run the following command inside the Converse.js
|
|
directory:</p>
|
|
<div class="highlight-python"><pre>npm install</pre>
|
|
</div>
|
|
<p>This will install all the development dependencies for Converse.js. If you are
|
|
curious to know what these are, take a look at whats under the <em>devDependencies</em> key in
|
|
<cite>package.json <https://github.com/jcbrand/converse.js/blob/master/package.json></cite>.</p>

<p>After running <tt class="docutils literal"><span class="pre">npm</span> <span class="pre">install</span></tt>, you will now have Grunt and Bower installed.</p>
|
|
<p>We use Bower to manage Converse’s front-end dependencies (e.g. Javascript that

|
|
<p>To fetch these dependencies, run:</p>
|

<div class="highlight-python"><pre>grunt fetch</pre>

|
|
<p>This will call Bower in the background to fetch all the front-end

<p>Converse.js uses <a class="reference external" href="http://requirejs.org">require.js</a> to asynchronously load dependencies.</p>
|
|
<p>If you want to develop or customize converse.js, you’ll want to load the

</div>
|
|
<p>require.js will then let the main.js file be parsed (because of the <em>data-main</em>

|
<p>The included minified JS and CSS files can be used for demoing or testing, but
|
|
you’ll want to configure <em>Converse.js</em> to suit your needs before you deploy it
|
|
on your website.</p>
|
|
<p><em>Converse.js</em> is passed its configuration settings when you call its
|
|
<em>initialize</em> method.</p>
|
|
<p>You’ll most likely want to call the <em>initialize</em> method in your HTML page. For
|
|
an example of how this is done, please see the bottom of the <em>./index.html</em> page.</p>
|
|
<p>Please refer to the <a class="reference internal" href="#configuration-variables">Configuration variables</a> section below for info on
|
|
all the available configuration settings.</p>
|
|
<p>After you have configured <em>Converse.js</em>, you’ll have to regenerate the minified
|
|
JS file so that it will include the new settings. Please refer to the
|
|
<a class="reference internal" href="#minification">Minification</a> section for more info on how to do this.</p>

<p>Not recommended for servers with lots of chat rooms.</p>
|
|
<p>For each room on the server a query is made to fetch further details (e.g.

<div class="admonition note">
|
|
<p class="first admonition-title">Note</p>
|
|
<p class="last">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.</p>
|
|
</div>
|
|
<p>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.</p>
|
|
<p>The POT file contains all translateable strings extracted from converse.js.</p>
|
|
<p>To make a user facing string translateable, wrap it in the double underscore helper
|
|
function like so:</p>
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="n">__</span><span class="p">(</span><span class="s">'This string will be translated at runtime'</span><span class="p">);</span>
|
|
</pre></div>
|
|
</div>
|
|
<p>After adding the string, you’ll need to regenerate the POT file, like so:</p>
|
|
<div class="highlight-python"><pre>make pot</pre>
|
|
</div>
|
|
<p>You can then create or update the PO file for a specific language by doing the following:</p>
|
|
<div class="highlight-python"><pre>msgmerge ./locale/af/LC_MESSAGES/converse.po ./locale/converse.pot -U</pre>
|
|
</div>
|
|
<p>This PO file is then what gets translated.</p>
|
|
<p>If you’ve created a new PO file, please make sure to add the following
|
|
attributes at the top of the file (under <em>Content-Transfer-Encoding</em>). They are
|
|
required as configuration settings for Jed, the Javascript translations library
|
|
that we’re using.</p>
|
|
<div class="highlight-python"><div class="highlight"><pre><span class="s">"domain: converse</span><span class="se">\n</span><span class="s">"</span>
|
|
<span class="s">"lang: af</span><span class="se">\n</span><span class="s">"</span>
|
|
<span class="s">"plural_forms: nplurals=2; plural=(n != 1);</span><span class="se">\n</span><span class="s">"</span>
|
|
</pre></div>
|
|
</div>
|
|
<p>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.</p>
|
|
<p>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):</p>
|
|
<div class="highlight-python"><pre>npm install po2json</pre>
|
|
</div>
|
|
<p>You can then convert the translations into JSON format:</p>
|
|
<div class="highlight-python"><pre>po2json locale/af/LC_MESSAGES/converse.po locale/af/LC_MESSAGES/converse.json</pre>
|
|
</div>
|
|
<p>Now from converse.json paste the data as a value for the “locale_data” key in the
|
|
object in the language’s .js file.</p>
|
|
<p>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:</p>
|
|
<div class="highlight-python"><pre>(function (root, factory) {
|
|
define("af", ['jed'], function () {
|
|
return factory(new Jed({
|
|
"domain": "converse",
|
|
"locale_data": {
|
|
// Paste the JSON data from converse.json here
|
|
}
|
|
})
|
|
}
|
|
}(this, function (i18n) {
|
|
return i18n;
|
|
}));</pre>
|
|
</div>
|
|
<p>making sure to also paste the JSON data as value to the “locale_data” key.</p>
|
|
<div class="admonition note">
|
|
<p class="first admonition-title">Note</p>
|
|
<p class="last">If you are adding translations for a new language that is not already supported,
|
|
you’ll have to make one more edit in ./locale/locales.js to make sure the
|
|
language is loaded by require.js.</p>
|
|
</div>
|
|
<p>Congratulations, you’ve now succesfully added your translations. Sorry for all
|
|
those hoops you had to jump through.</p>
