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 react-native-webrtc according to their install guide. Then add react-native-peerjs:
yarn add react-native-peerjs
Just refer to the PeerJS documentation. Here is an example:
importPeerfrom'react-native-peerjs';constlocalPeer=newPeer();localPeer.on('error',console.log);localPeer.on('open',localPeerId=>{console.log('Local peer open with ID',localPeerId);constremotePeer=newPeer();remotePeer.on('error',console.log);remotePeer.on('open',remotePeerId=>{console.log('Remote peer open with ID',remotePeerId);constconn=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!');});});
