How to Create Server in Node js

const http = require('http');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World\n');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

Simple As it is .

We have to give Host Name and port number , and rest is the server code , that is

http.createServer(req, res)
server.listen(port, hostname) .
