PeerJS is a JavaScript library that wraps WebRTC in a simple API, letting you implement peer-to-peer data transfer and voice and video calls between browsers in a few lines of code. A broker server called PeerServer handles WebRTC's complex signaling (SDP exchange, ICE candidate delivery), and each peer finds and connects to others by ID. You can use the public PeerServer or run your own server with Node.js, and the actual media and data travel directly between peers without passing through the server.
simplifies WebRTC peer-to-peer data, video, and audio calls.
