A ready-to-go pluggable transport utilizing WebRTC datachannel written in Go.
A Config defines the behavior of the transport. A Config could be used to configure:
- Automatic signalling when establishing the PeerConnection
- IP addresses to be used for ICE candidates
- Port range for ICE candidates
- UDP Mux for serving multiple connections over one UDP socket
A Dialer is created from a Config and is used to dial one or more Conn backed by WebRTC DataChannel.
On its first call to Dial, the Dialer will create a new PeerConnection and DataChannel. On subsequent calls, the Dialer will reuse the existing PeerConnection and DataChannel.
A Listener is created from a Config and is used to listen for incoming Conn backed by WebRTC DataChannel. It looks for incoming SDP offers to establish new PeerConnections and also looks for incoming DataChannels on existing PeerConnections.
One Listener can maintain multiple PeerConnections and on each PeerConnection multiple DataChannels may co-exist.
A Listener requires a valid SignalMethod to function.
A Conn is created from a Dialer and is used to send and receive messages. Each Conn is backed by a single WebRTC DataChannel.
