WebRTC relay-инфраструктура, которая просто работает

const iceServers = await fetch('https://api.turnpipe.io/v1/credentials', {
  headers: { 'Authorization': `Bearer ${API_KEY}` }
});

const pc = new RTCPeerConnection({
  iceServers: [
    {
      urls: 'stun:global.stun.turnpipe.io:3478'
    },
    {
      urls: 'turn:eu-west.relay.turnpipe.io:443?transport=tcp',
      username: 'tp_1a2b3c',
      credential: 'secret_token'
    }
  ]
});
