A lightweight WebSocket-based signaling server for WebRTC applications, built with Swift and Vapor.

This signaling server facilitates WebRTC peer connections by:

• Relaying signaling messages between WebRTC peers
• Managing user presence and connection events
• Handling WebRTC signaling protocol (offers, answers, ICE candidates)

swift build
swift run

The server will be available at http://localhost:8080.

Connect to the WebSocket endpoint at /signals to exchange WebRTC signaling data.

The server supports the following event types:

• user-joined: Announces when a new user joins
• offer: Contains SDP offer for establishing connection
• answer: Contains SDP answer in response to an offer
• ice-candidate-generated: Shares ICE candidates for connection
• ice-candidates-removed: Notifies when ICE candidates are removed

• Built on Swift Vapor framework
• Uses Swift Concurrency (async/await)
• Utilizes Swift NIO for non-blocking networking
• Actor-based client management for thread safety

Clients should:

1. Connect to the WebSocket endpoint
2. Announce themselves with a user-joined event
3. Listen for other peers joining
4. Exchange WebRTC offers/answers and ICE candidates
5. Establish direct peer connections once signaling is complete
