A small demo on the use of socket io and express to make a simple chatting app
to run it simply type the following commands in the terminal.
git clone https://github.com/Poufy/chattingapp.git
npm install --save express
npm install --save socket.io
node index.js
and open your browser on http://localhost:3000/
#TODO Instead of using the map for the user names just send the username to the server and emit it to all the other clients and handle the printing there.
