WebRTC's connections requires a signalling server to resolve how peers can connect over the internet. A signaling servers job is to act as
a link in the middle of two peers that wish to connect to each other. WebRTC doesn’t specify a transport mechanism for
signaling information, so a WebSocket is used to send and receive messages from client to server.The signalling server
does not need to understand or interpret the signalling data. SDP data is sent to enable WebRTC class, but the
socket doesn’t need to worry about understanding it. What is important when the ICE instructs the websocket to send
signaling data to another peer. When the other peer receives information it knows how to receive the information and
deliver it to its ownICE subsystem. All the signalling server has to do is channel the information back and forth,
the context doesn’t matter at all to the signalling server.
- Install Git to clone the project with the repositories URL or download the .zip from the Github:
- Install Node
cd /webrtc-signalling-server- Install npm packages
npm install
- WebRTC requires a secure websocket(WSS) to allow peers to exchange data between each other so SSL certs need to be provided in order for the websocket to allow WebRTC communicate. Let's Encrypt provide SSL certs.
- Run the server
node .- Server is served on
