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.
#About WebRTC 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.

#About Socket.io 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.

#Deploy steps ##run your server Make sure Node is installed first, then open your terminal
cd Server
npm install
node index.js
##run your web client
- open localhost:3000 on your browser
- type in your nickname and submit
##run your iOS client
- 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! 😄
