webrtc-signal-server

A general WebRTC signal server for peer-to-peer communication, written in Rust and powered by async networking and WebSockets.

Features

• Simple WebSocket-based signaling for WebRTC peers
• Peer registration and discovery
• Message relay between peers
• Asynchronous, scalable, and easy to deploy

Usage

Add to your workspace or build as a standalone binary:

cargo build --release

Run the server (default port: 9000):

cargo run --release

The server listens for WebSocket connections on 0.0.0.0:9000.

Protocol

Clients communicate with the server using JSON messages:

{ "type": "register", "peer_id": "your-unique-id" }

List Peers

{ "type": "list_peers" }

Relay Message

{ "type": "relay", "to": "target-peer-id", "data": { ... } }

Server Responses

• List of peers:

  { "type": "peers", "peers": ["peer1", "peer2"] }
  

• Relayed message:

  { "type": "relay", "from": "peer1", "data": { ... } }
  

• Error:
