junction-caps

Entity Capabilities middleware built on Junction and Node. This lets you see which additional features the user's XMPP client supports (such as audio/video chat, multi user chats, avatars, etc.). This middleware also supports Entity Capability extensions as specified in the legacy specification.

Installation

To get the stable release:

npm install junction-caps

To get the latest development version:

npm install git://github.com/Daniel15/junction-caps.git

Usage

To parse entity capabilities, use the capabilities middleware:

var capabilities = require('junction-caps').capabilities,
    capabilitiesParser = require('junction-caps').capabilitiesParser;

var app = junction.create();
app.use(capabilitiesParser());
app.use(capabilities(function(handler) {
    handler.on('capabilities', function(jid, caps) {
        console.log(jid + ' supports Multi-User chat? ' + caps.features.muc + ', XHTML? ' + caps.features.xhtml);
    })
}));

caps.features will contain a hash of user-friendly names for the most common capabilities, and whether the buddy's client supports it. caps.rawFeatures contains a list of all the raw feature namespaces.
