Collaborators wanted!!

I'm too busy to improve PeerJS, but I don't want it to fall in dust so if anyone wants to become a maintainer, anyone is welcome!! I'll give support with any problem when coding and will be reviewing PRs. I'll also be in charge of the server and sysadmin things.

it is a good opportunity to gain experience too, if you think it's too big for you, don't worry! I'll be mentoring you (sometimes :) )

If you want to become a maintainer, you can write me to kidandcat@gmail.com

PeerJS: Simple peer-to-peer with WebRTC

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.

http://peerjs.com

Setup

Include the library

with modules: npm install peerjs or yarn add peerjs and the usage:

import Peer from 'peerjs';

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.

Data connections

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);
  });
});

Media calls

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) {
    // Show stream in some <video> element.
  });
}, function(err) {
  console.log('Failed to get local stream' ,err);
});

Answer

navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia || navigator.mozGetUserMedia;
peer.on('call', function(call) {
  navigator.getUserMedia({video: true, audio: true}, function(stream) {
    call.answer(stream); // Answer the call with an A/V stream.
    call.on('stream', function(remoteStream) {
      // Show stream in some <video> element.
    });
  }, function(err) {
    console.log('Failed to get local stream' ,err);
  });
});
