This tutorial is going to take you through on how to Install Node.js on Ubuntu 22.04. Node.js is a cross-platform, open-source back-end JavaScript runtime environment that uses the V8 engine to execute JavaScript code outside of a web browser. Node.js allows developers to utilize JavaScript to create command-line tools and server-side scripting, which involves running scripts on the server before sending the page to the user’s browser. As a result, Node.js symbolizes a “JavaScript everywhere” paradigm, bringing web application development together around a single programming language rather than separate languages for server-side and client-side scripts.
The event-driven architecture of Node.js allows for asynchronous I/O.
These design choices are intended to improve throughput and scalability in web applications that have a lot of input/output activities, as well as for real-time Web applications (e.g., real-time communication programs and browser games).

- In case you have several versions installed, you can switch to specific version e.g.
nvm use 16.14.2Introduction to Node.js on Ubuntu 22.04
- Fire up your favorite text editor, in this example I will use nano.
nano demo.jsThen paste the sample code below.
const http = require('http');
const hostname = '127.0.0.1';
const port = 5000;
const server = http.createServer((req, res) => {
res.statusCode = 200;
res.setHeader('Content-Type', 'text/plain');
res.end('Hello from itnixpro');
});
server.listen(port, hostname, () => {
console.log(`Server running at http://${hostname}:${port}/`);
});
- Save the file by pressing
ctrl+sthen close it by pressingctrl+xif you are using nano text editor in your example. - Start your server by running the command node followed by your file name as shown below.
node demo.js- If everything goes well, you should be able to access your page in the browser through URL and port that was specified in the code above e.g.
