webRTC-over-websockets

Small demo of webRTC over websockets, using node.js and HTML5. It allows you to setup peer2peer and group chat calls. You can also add new users on the fly (but not rooms, there are predefined - see data directory).

Ideally, would be best to use XMPP (with strophe.js library) for signaling since it has presence and roster support, with BOSH or even better websockets over XMPP.

Files

Data

• data/people.json this is the roster file, where people are defined.
• data/rooms.json this is where rooms are defined

JS files

• js/main.js this is the file responsible for UI updates
• js/webrtc.js this is the webrtc wrapper
• js/signaling.js signalling client, implemented using websockets
• js/bandwitdh.js this is the file for bandwith estimation
• js/adapter.js this is the file used in webrtc demo's, it wraps browser dependencies

Server

• websocket-server.js this is the websocket server, used by node.js. It requires websocket library, you can install it using the following command :
• $ npm install websocket

After this you can run the server with: $ node server.js [settings.json]

• index.html portal page (see settings below)

Settings

Defined in settings.json, in case you don't provide it:

• refreshRate [default 5s], refresh presence rate to all connected users
• autoCall [default true], whether to call all people in the room as soon as you connect to it
• acceptNewUsers [default false], whether to accept users that are not defined in people.json file

Things to change if you install the app on your server:

• in js/main.js change the websocket address to point to your server
• change json files data/people.json and data/rooms.json with your address book
• change images
