RTC Data Connection

A slightly simplified and smoothed-over wrapper around the native WebRTC peer connection and data channels APIs. This is for data connections only - no audio/video streams. See simple-rtc-data-connection for an even simpler version and example stuffs.

Installation

npm install rtc-data-connection

Usage

var RTCDataConnection = require('rtc-data-connection');
var dataConnection = new RTCDataConnection();

dataConnection.on('offer', function (offer) {
    // send offer to peer
    socket.emit('offer', offer);
})
dataConnection.on('answer', function (answer) {
    // send answer to peer
    socket.emit('answer', answer);
})
dataConnection.on('candidate', function (candidate) {
    // send candidate to peer
    socket.emit('candidate', candidate);
})
dataConnection.on('open', function () {
    // connection opened!
    this.send('hello, world!');
})

// assume a websocket signaling server
socket.on('offer', function (offer) {
    // set local description and create an answer
    dataConnection.setDescription(offer);
    dataConnection.createAnswer();
});
socket.on('answer', function (answer) {
    dataConnection.setDescription(answer);
});
socket.on('candidate', function (candidate) {
    dataConnection.addCandidate(candidate);
});

// someone needs to be the first to offer...
dataConnection.createOffer();

Using in node w/ wrtc

This package was originally built for the browser, but it also works in node by leveraging the wrtc module. The module just needs to be installed and rtc-data-connection will use it.
