Console-Based Hello World

// console_example1.js
console.log('Hello UpdateGadh');

// Run with:
// node console_example1.js

Web-Based HTTP Server

A simple Node.js web server requires just three steps: import the http module, create the server, listen on a port.

// main.js
const http = require('http');

http.createServer(function (request, response) {
  response.writeHead(200, { 'Content-Type': 'text/plain' });
  response.end('Hello World
');
}).listen(8081);

console.log('Server running at ');

Run and Test

node main.js
# Open browser at:
# 
# Output: Hello World

Modern Alternative

For production apps, use the Express framework ÔÇö it builds on http with routing, middleware, and much cleaner syntax:

const express = require('express');
const app = express();
app.get('/', (req, res) => res.send('Hello World'));
app.listen(8081);
