Running a node.js Hello World.

Now that node is installed, we can create a simple Hello World application. Here is the code for creating this:

var http = require("http")

http.createServer(function (request, response) {

    // Send the HTTP header
    // HTTP Status: 200 : OK
    // Content Type: text/plain
    response.writeHead(200, {'Content-Type': 'text/plain'})

    // Send the response body as "Hello World"
    response.end('Hello World\n')
}).listen(3000)

// Console will print the message
console.log('Server running')
