Node.js is an open-source platform built on Chrome’s JavaScript runtime environment to help developers build fast and scalable network applications. It runs on the V8 engine and executes JavaScript code outside a web browser. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.

Once we have installed Node.js, let’s build our first web server. Create a file named app.js:
vim app.jsThe add:
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');
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});Then run your web server using the following command:
$ node app.jsThis runs the service on port 3000:
$ sudo ss -tuenlp | grep 3000
tcp LISTEN 0 128 127.0.0.1:3000 0.0.0.0:* users:(("node",pid=13377,fd=18)) ino:50295 sk:7 <-> Visit http://localhost:3000 and you will see a message saying “Hello World“.
