PeerJS provides a complete, configurable, and easy-to-use peer-to-peer API built on top of WebRTC, supporting both data channels and media streams.
Include the library
<script src="http://cdn.peerjs.com/0.3/peer.js"></script>Create a Peer
Get a free API key. Your id only needs to be unique to the namespace of your API key.
var peer = new Peer('pick-an-id', {key: 'myapikey'});
// You can pick your own id or omit the id if you want to get a random one from the server.Connect
var conn = peer.connect('another-peers-id');
conn.on('open', function(){
conn.send('hi!');
});Receive
peer.on('connection', function(conn) {
conn.on('data', function(data){
// Will print 'hi!'
console.log(data);
});
});Call
navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;
navigator.getUserMedia({video: true, audio: true}, function(stream) {
var call = peer.call('another-peers-id', stream);
call.on('stream', function(remoteStream) {
