This tutorial will help a user to create an http server in Node.js and run an applications at server side.

Follow the steps as below:

1. Install Node.js
2. Lets create a file test.js which we will place in the root directory of our application

To create an http server we will use a module of Node named server in our file test.js

// the builtin function require helps to use any module of Node.js   

var testhttp = require("http"); 

// In the below line createServer is a function in http module of Node.js    

var server = testhttp.createServer(on_Request);

function on_Request(request, response) {

// In the below line writeHead is a function of response object

   response.writeHead(200, {"Content-Type": "text/plain"});

// In the below line write is a function of response object

response.write("Yes my testhttp server is working..");

//end function of response object ends the response
response.end();    

}

// listen is a function of the object that is returned by the function createServer
// the listen function needs one paramater that represent the port number on which the testhttp server //will listen the reqeusts.

server.listen(8831);

3-Now go to the terminal and execute the following command

user@username:~$ cd /var/www/html/project_root_directory

user@username:/var/www/html/project_root_directory$ nodejs test.js

4- Now open a browser and write the following url:

http://localhost:8831/test.js

output on the browser: Yes my testhttp server is working..
output on the terminal:  testhttp server has started
