Note: Requires HTTPS or localhost environment.

Overview

This section ties together everything you've learned: local media capture → create connection → signaling exchange → remote video playback. Core flow is about 80 lines of code.

Notes

• HTTPS: Must use HTTPS outside localhost; can use ngrok or Cloudflare Tunnel to expose local services
• STUN server: stun.l.google.com:19302 is Google's public STUN, for demo only; build or buy TURN service for production
• TURN relay: In strict network environments (enterprise network, symmetric NAT), STUN is not enough, must configure TURN server; otherwise connection failed
• Echo issue: This example has local video with muted, remote audio without — if still getting echo, check system sound card settings or use headphones
