We can easily set up an up and running HTTP server on our desktop that runs a web application developed in node.js. We just need to write our code in a separated JavaScript file and execute it.

var http = require('http');
var server = http.createServer(function (req, res) {
 res.writeHead(200, {'Content-Type':'text/plain'});
 res.end('Hello World!\n');

The following video clip goes over this code sample, shows its execution on our desktop and explains it.
