Please check actual situation here

Integrated WebSocket Client & Server is available, which can be used separately or for signaling.

For an example usage, check here

import nodeDataChannel from 'node-datachannel';

// Log Level
nodeDataChannel.initLogger('Debug');

// Integrated WebSocket available and can be used for signaling etc
// const ws = new nodeDataChannel.WebSocket();

let dc1 = null;
let dc2 = null;

let peer1 = new nodeDataChannel.PeerConnection('Peer1', {
  iceServers: ['stun:stun.l.google.com:19302'],
});

peer1.onLocalDescription((sdp, type) => {
  peer2.setRemoteDescription(sdp, type);
});
peer1.onLocalCandidate((candidate, mid) => {
  peer2.addRemoteCandidate(candidate, mid);
});

let peer2 = new nodeDataChannel.PeerConnection('Peer2', {
  iceServers: ['stun:stun.l.google.com:19302'],
});

peer2.onLocalDescription((sdp, type) => {
  peer1.setRemoteDescription(sdp, type);
});
peer2.onLocalCandidate((candidate, mid) => {
  peer1.addRemoteCandidate(candidate, mid);
});
peer2.onDataChannel((dc) => {
  dc2 = dc;
  dc2.onMessage((msg) => {
    console.log('Peer2 Received Msg:', msg);
  });
  dc2.sendMessage('Hello From Peer2');
});

dc1 = peer1.createDataChannel('test');

dc1.onOpen(() => {
  dc1.sendMessage('Hello from Peer1');
});

dc1.onMessage((msg) => {
  console.log('Peer1 Received Msg:', msg);
});
