rtcfire (WIP)

A simple WebRTC + Firebase Realtime Database JS library for multi-user video chat.

WARNING: This library is experimental, and not battle-tested. Bug reports and PRs welcome.

See demos

Installation

Install with npm:

npm install rtcfire

Dependencies

The only dependency is the Firebase JS SDK (npm install firebase), which is a peer dependency and not directly required by this library.

Usage

import { rtcFireSession } from 'rtcfire';

let session = rtcFireSession({
  // list of user IDs, including your own!
  // when the set of participants changes, call:
  //   session.participants = [user.uid, 'uid1'];
  participants: [user.uid, 'uid1', 'uid2', ...],
  // the current user's uid, probably from Firebase Auth
  myId: user.uid,
  // root path for WebRTC negotiation
  // (don't forget to protect these behind security rules!)
  // (call firebase.initializeApp(config) before calling this)
  negotiationRef: firebase.database().ref('rtcnegotiations'),
  // Set the local <video> stream
  onMyStream: stream => myVideo.srcObject = stream,
  // Set the <video> stream for the given participant
  onParticipantStream: (pid, stream) => videos[pid].srcObject = stream,
});

Security rules

Don't forget to write appropriate security rules for your Realtime Database! See example_rtdb_rules.rules for an example that uses the default negotiationRef paths.
