Questions tagged [simplewebrtc]

SimpleWebRTC is an open source javascript library for joining and managing mesh p2p WebRTC conferences. Questions using this tag should be specific to this library.

Questions about the SimpleWebRTC library should use the simplewebrtc tag.

WebRTC is a technology stack for establishing (S)RTP and SCTP streams between peers. Peers are normally browser sessions.

p2p means "peer to peer," indicative of a transport between peers without a server or translation layer in the middle.

SimpleWebRTC normalizes browser API differences for peer connections and user media access. The library manages multiple RTCPeerConnections to provide a clean API for joining mesh (fully connected graph of p2p sessions) "rooms."

See https://simplewebrtc.com/ for more information and demos. See https://github.com/andyet/simplewebrtc for source code and issues.
