The unstoppable secret superpower of WebRTC
summary
WebRTC’s real power is the data channel: a peer‑to‑peer path that sends chat, game state, files and even livestreams without routing through your server. Demo uses an Angular frontend and Node/WebSocket signaling to pair browsers, then RTCPeerConnection + STUN/ICE (TURN as costly fallback) to stream canvas drawing and chunked file transfers (64KB/message limit; Firefox now accepts ~1GB messages). Connections encrypt by default; Safari required recent fixes for data‑only, Edge still lacks full data‑channel support.
