Creating a NodeJS Server

With the http module in Nodejs:

var http = require('http');

http.createServer(function (req, res) {
res.write('Teknosos');
res.end();
}).listen(8080);

With Expressjs:

To install Express:

npm i express

const express = require('express')
const app = express()
const port = 3000

app.get('/', (req, res) => res.send('Teknosos'))

app.listen(port, () => console.log(`My sample application is running on ${port}!`))
