HTTP server with node js

 

const http = require('http'); // Loads the http module

http.createServer((req, res) => {

    // 1. Tell the browser everything is OK (Status code 200), and the data is in plain text

    res.writeHead(200, {

    'Content-Type': 'text/plain'

    });

    // 2. Write the announced text to the body of the page

    res.write('Hello, World!\n');

    // 3. Tell the server that all of the response headers and body have been sent

    res.end();

   

}).listen(2000); // 4. Tells the server what port to be on

console.log("server is running on port : ",2000);
