javascript - Web server not starting -

I'm trying to implement

The problem I am facing is: I downloaded and followed the command: npm install socket.io , I get this message: (Sorry for the link to the drive, but I have There is no necessary repops yet to post magazines)
After that I command node server JS

Server.js:

  // Created by coffee script 1.9.1 (function () {var io; io = require ('Socket.io'). Listen (4000); io.sockets .on ('connection', function (socket) {});}). Call (this);  

which is running at CMD prompts but moves forever . Any help would really be appreciated.

It should run forever. This node.js works how this node process is Your server will connect your client application through your port 4000.
