strophe.disco.js

Plugin for strophe.js to provide Service Discovery (XEP-0030).

Install

npm install strophejs-plugin-disco

There are two plugins available.

Plugin A (default)

This plugin allows to send disco queries and registers handlers that respond to incoming queries.

Usage

var c = new Strophe.Connection('bosh-service');
c.connect(jid,pw);
c.disco.info(jid,callback);

Run Specs

use node with jasmine-node plugin to run the specs

ToDo

• cleanup stanza specs using Strophe.Builder instead of strings

Plugin B

The plugin facilitates client and server side handling of discovery messages.

Client Side

The plugin provides to methods (info and items) on top of the disco object that is added to the connection. You use them as follows

var c = new Strophe.Connection('http://localhost/xmpp-httpbind');
c.connect('andi@psi/strophe','andi');
c.disco.info('andi@psi/psi');

You can also pass a node, success and error handlers to the method. The items method behaves in the same way. Just make sure that your success and error handlers are passed after the node (if any).

Server Side

The module adds response handlers to info and item queries. The disco object added to the connection has members for features and identity that will be used to populate the disco#info response.

 <iq xmlns='jabber:client' from='andi@psi/strophe' to='andi@psi/strophe2' type='result' id='4774:sendIQ'><query xmlns='http://jabber.org/protocol/disco#info'><identity name='strophe'/><feature var='http://jabber.org/protocol/disco#info'/><feature var='http://jabber.org/protocol/disco#items'/></query></iq>

You can additional nodes using addNode, e.g. c.disco.addNode('aNode', { items: [{node: 'aNode', name: 'aName'}] });

and then query for them using the items method

c1.disco.items('andi@psi/strophe', 'aNode', function(s) { console.log(Strophe.serialize(s)) ; } )

See the specs for details.

Tests

To run the specs you should install jasmine-tool for nodejs via npm and update the references to the external libraries (Strophe, jQuery) in jasmine.json. After that you run

$> jasmine mon

and navigate your browser to http://localhost:8124 to view the specs executing.
