Socket.IO P2P provides an easy and reliable way to setup a WebRTC connection between peers and communicate using the socket.io-protocol.
Socket.IO is used to transport signaling data and as a fallback for clients where the WebRTC
PeerConnectionis not supported. Adding a simple piece of middleware to your socket.io setup enables this – no need to hand roll your own signaling exchange or set up, deploy and scale new servers.
