Node.js is a popular technology that enables developers to build fast, scalable and highly reliable web applications. It is important to note that NodeJS runs on the server side and not in the browser like JavaScript does.

In this tutorial, you will learn how to install NodeJS on Ubuntu from the NodeSource repository. Basically there are 4 easy Steps to Install Node JS in Ubuntu 20.04 from NodeSource repository

Step 1 – Update Your System

The first step is to update the package list, which will make sure that your system is up-to-date with all the latest bug fixes and security patches.

To update the package list, open a terminal window and type the following command:

# sudo apt update && sudo apt upgrade -y

Step 2 – Add Node Repository and Update Package List for Node JS

In this step, you will need to add a new repository to your system. This is because the default repositories are not up-to-date with the latest version of Node.js. The repository you will be adding is called nodejs.org and it will include the latest version of Node.js, which is 18.x at the time of writing this tutorial.

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