WebRTC connection

Provides a tool to create pool of WebRTC peer connections using different types of signaling.

Installation

npm install webrtc-connection

Signaling

WebSockets signaling

const signaling = new SocketIoSignaling('https://signaler.local:8881', 'abc');
await signaling.prepare();
const connectionsPool = new WebRtcConnectionsPool();
const connection = connectionsPool.connect(signaling);
connection.addOnOpenCallback(() => {
    // A peer has been connected
});
 
connectionsPool.sendMessage('Hi!');

Manual signaling

const signaling = new ManualSignaling();
const connectionsPool = new WebRtcConnectionsPool();
const connection = connectionsPool.connect(signaling);
connection.addOnOpenCallback(() => {
    // A peer has been connected
});
 
signaling.bindOnOutgoingDataCallback((message) => {
    // Send this signaling message manually to any other user
});
 
// Apply a signaling message which was received from another user
signaling.applyRemoteResponse(remoteMessage);
 
connectionsPool.sendMessage('Hi!');

Local signaling

Connects several peers on the same page from the same browser

const signaling = new LocalSignaling();
const connectionsPool = new WebRtcConnectionsPool();
connectionsPool.connect(signaling);
signaling.initiate(2); // 2 - connections number
connectionsPool.sendMessage('Hi!');

Using pool

Send to all connected peers

const connectionsPool = new WebRtcConnectionsPool();
connectionsPool.sendMessage('Hi!')

Receive messages

const connectionsPool = new WebRtcConnectionsPool();
connectionsPool.addOnMessageCallback((message, peerId) => {
    // console.log(message)
})
