A simple chat system demostrating how to build chat applications based on WebRTC, socket.io & Node.js
This system including a web server, a web client, and an iOS client, supports realtime text/voice/video chat.
The iOS client supports voip socket mode which means it could receive message even in background
Note: Since voip mode is deprecated from iOS 10, so you can no longer receive messages from background anymore. Refer here.
WebRTC is an open framework for the web that enables Real Time Communications in the browser. It includes the fundamental building blocks for high-quality communications on the web, such as network, audio and video components used in voice and video chat applications.

Socket.IO is a JavaScript library for realtime web applications. It enables realtime, bi-directional communication between web clients and servers. It has two parts: a client-side library that runs in the browser, and a server-side library for node.js. Both components have a nearly identical API. Like node.js, it is event-driven.
Socket.IO primarily uses the WebSocket protocol with polling as a fallback option, while providing the same interface. Although it can be used as simply a wrapper for WebSocket, it provides many more features, including broadcasting to multiple sockets, storing data associated with each client, and asynchronous I/O.

Make sure Node is installed first, then open your terminal
cd Server
npm install
node index.js
- open localhost:3000 on your browser
- type in your nickname and submit
- install dependency with
pod install - open xcworkspace file
- build and run
- upon application launch, type in your host address(server address you are running on)
- choose anyone online and start video chat
Enjoy chating! 😄
