Video-chat-app

This is a video chat app using WebRTC and WebSockets. It is built using Node.js, Express, and Socket.io.

We implemented a signaling server using Socket.io to exchange the WebRTC signaling messages (offer, answer, and candidate) between the peers. The signaling server is also responsible for broadcasting the list of active users to all connected users.

The WebRTC peer-to-peer communication requires an ICE server to establish a connection between the peers. In this app, we used the Google STUN server.

Getting started

• npm start
