Working with a Git repository

We have cloned the Samplerepository on our local machine. Now we will see how to work with the Git repository:

1. Create a Node.js Hello World application that will create an HTTP server and respond to all requests on port 8080 with the string Hello World. Here is the sample code for the Node.js application:

var http = require("http"); 
 
http.createServer(function (request, response) { 
 
   // Send the HTTP header  
   // HTTP Status 200 OK 
   // Content Type is text/plain 
   response.writeHead(200, {'Content-Type': 'text/plain'}); 
    
   // Send response body as "Hello World" 
   response.end('Hello World\n'); 
}).listen(8080); 
 
// Print message 
console.log('Server running at http://127.0.0.1:8080/'); 

2. Save the code in  main.js and add this file to our Git repository.
3. Check untracked changes in our Git repository with following command:

$git status 
On branch master 
Your branch is up to date with 'origin/master'.
