A multi-user real-time audio and video communication application based on WebRTC. See the demo at: https://world-meeting.herokuapp.com

• Join/leave room
• Call with video/audio
• Send messages/files

Frontend:

yarn
cd frontend
yarn
yarn dev

Then open: https://localhost/#/

Backend:

cd backend
yarn
yarn dev

1. Download ngrok

2. Run the http command to forward the local dev server to public network

   ngrok http 443

3. Inspect the app using the xxx.ngrok.io link

• Use native RTCPeerConnection to form a Mesh topology network in a single room
  • Each client maintains (n - 1) RTCPeerConnection to connect with different users in the same room
• Use Socket.IO backend as a signal to help discover different users, passing signals, user updates and messages
