React Native PeerJS

react-native-webrtc has brought WebRTC to React Native. PeerJS is a simple API to work with WebRTC in the Browser.

I made it so that PeerJS works with react-native-webrtc in a React Native application.

Install

Install react-native-webrtc according to their install guide. Then add react-native-peerjs:

yarn add react-native-peerjs

Usage

Just refer to the PeerJS documentation. Here is an example:

import Peer from 'react-native-peerjs';
 
const localPeer = new Peer();
localPeer.on('error', console.log);
 
localPeer.on('open', localPeerId => {
  console.log('Local peer open with ID', localPeerId);
 
  const remotePeer = new Peer();
  remotePeer.on('error', console.log);
  remotePeer.on('open', remotePeerId => {
    console.log('Remote peer open with ID', remotePeerId);
 
    const conn = remotePeer.connect(localPeerId);
    conn.on('error', console.log);
    conn.on('open', () => {
      console.log('Remote peer has opened connection.');
      console.log('conn', conn);
      conn.on('data', data => console.log('Received from local peer', data));
      console.log('Remote peer sending data.');
      conn.send('Hello, this is the REMOTE peer!');
    });
  });
});
 
localPeer.on('connection', conn => {
  console.log('Local peer has received connection.');
  conn.on('error', console.log);
  conn.on('open', () => {
    console.log('Local peer has opened connection.');
    console.log('conn', conn);
    conn.on('data', data => console.log('Received from remote peer', data));
    console.log('Local peer sending data.');
    conn.send('Hello, this is the LOCAL peer!');
  });
});
