Socket.io P2P

Overview

Socket.IO P2P establishes a bidirectional events channel between two peers with a server fallback by setting up a WebRTC connection between peers and communicates using the socket.io-protocol.

Socket.IO is used to transport signaling data and as a fallback for clients where the WebRTC PeerConnection is not supported.

Usage

Server:

var io = require('socket.io')(server);

var p2p = require('socket.io-p2p-server').Server;

io.use(p2p);

Client:

var P2P = require('socket.io-p2p');

var io = require('socket.io-client');

var socket = io();

var p2p = new P2P(socket);

p2p.on('peer-msg', function (data) {

    console.log('From a peer %s', data);

});
