How to Install Latest Node.js on Ubuntu

If you’ve been exploring the world of front-end and JavaScript, you might have come across Node.js. It is a server-side framework that uses Google’s V8 engine to execute JavaScript code. Developers can use Node.js as it provides them with an easy way to build fast and scalable network applications, using single-threaded asynchronous events.

In this article, we will see how to install Node.js on Ubuntu and its derivatives via a new official PPA repository. If you are new to Ubuntu or any other Linux operating system, then be sure to check out our beginner’s guide first.

You can also use the popular Node Version Manager (NVM) for installing specific Node.js version on your system.

Step 1 – Configuring Node.Js PPA

Node.js releases are available in two types, one is the LTS release, and the other is the current release. Choose any one version of your choice or as per the project requirements. Let’s add the PPA to your system to install Nodejs on Ubuntu.

• Use Current Release –
During the last update of this tutorial, Node.js 18 is the current Node.js version available.

sudo apt-get install curl 
curl -sL https://deb.nodesource.com/setup_18.x | sudo -E bash - 

sudo apt-get install curl 
curl -sL https://deb.nodesource.com/setup_16.x | sudo -E bash - 

For this tutorial, I am using the latest current release and added their PPA to my system.

Step 2 – Install Node.js on Ubuntu

You have successfully configured Node.js PPA in your Ubuntu system. Now execute the below command to install Node on and Ubuntu using apt-get. This will also install NPM with node.js. This command also installs many other dependent packages on your system.

sudo apt install nodejs 

That’s it. This will install Node.js on your Ubuntu system.

Step 3 – Check Node.js and NPM Version

After installing node.js verify and check the installed version. You can find more details about current version on node.js official website.

node -v  

v16.15.1

Also, check the npm version

npm -v  

7.13.0

Step 4 – Create Demo Web Server (Optional)

This is an optional step. Suppose you want to test your node.js install. Let’s create a web server with “Hello World!” text. Create a file server.js

sudo nano server.js 

and add the following content

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello Worldn');
}).listen(3000, "127.0.0.1");
console.log('Server running at http://127.0.0.1:3000/');

Save the file and close. Then start the Node application using the following command.

node server.js 

debugger listening on port 5858
Server running at http://127.0.0.1:3000/

You can also start the application with debugging enabled with the following commands.

node --inspect server.js 

Debugger listening on ws://127.0.0.1:9229/938cf97a-a9e6-4672-922d-a22479ce4e29
For help, see: https://nodejs.org/en/docs/inspector
Server running at http://127.0.0.1:3000/

The web server has been started on port 3000. Now access http://127.0.0.1:3000/ URL in browser. Now you will need to configure a front-end server for your app.
