WebRTC Mesh Demo (1:1 & group)

What this project contains

• server.js: simple Express + Socket.IO signaling server
• public/index.html: client UI
• public/client.js: client logic building RTCPeerConnections (mesh topology)

Run

1. npm install
2. npm start
3. Open http://localhost:3000 in multiple browser windows or devices and use the same room name to connect.

Notes

• This demo uses a mesh topology: every participant creates a PeerConnection to every other participant. Works well for small groups (<=4). For larger groups, use an SFU (mediasoup, Janus, Jitsi, or commercial SFUs) to reduce upstream bandwidth and CPU.
• You can add a TURN server in RTCPeerConnection iceServers for better NAT traversal.
• This is a minimal demo. For production, add auth, HTTPS, TURN, reconnection logic, proper UI and bandwidth controls.
