chatroom demo

Until now, I have to abandon create-react-app frame, for port conflict.

I have solved the conflict between the client-side port 3000 and server-side port 3001, by adding proxy: http://localhost:3001 to the package.json, but I have no idea how to solve CORS caused by socket.io, which listening on port 3000.

Migrate to pure express, and try to use webpack myself.

Chatroom demo with limited functions. To get it to work as expected will need more works, but it fulfills my initial purpose to try to use socket.io.Continuing.

Add online/offline state tommorrow, together with some small modifications.

In this demo, I have learnt how to use socket.io and how to create single page web application with React. It meets my current needs. So just stop here, and I will find something else to learn.

Integrate with react-router. After this, hot-module-reload can't work as expected, for react-router's routing mechanism conflicts with browsers' refreshing mechanism. Besides this, the way to inject state is not perfect(/src/pages/js/BasePage.js).
