How to Install Node.js on Ubuntu

In this tutorial, we will guide you through the process of installing Node.js on Ubuntu. Node.js is a powerful runtime environment that allows you to run JavaScript on the server-side, enabling you to build scalable and efficient web applications.

What is Node.js?

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside of a web browser. It uses the V8 JavaScript engine from Google Chrome and provides a rich set of libraries and frameworks that make it easy to build server-side applications in JavaScript.

Installation Steps

Step 1: Update Package Index

Before installing Node.js, it’s always a good idea to update the package index and ensure that you have the latest version of packages installed on your system. You can do this by running the following command in your terminal:

sudo apt update

Step 2: Install Node.js

To install Node.js on Ubuntu, you can use the NodeSource repository. First, you need to install the NodeSource PPA and Node.js package by running the following commands:

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

Step 3: Verify Installation

To verify that Node.js has been successfully installed, you can check the version of Node.js and npm (Node Package Manager) by running the following commands:

node -v
npm -v

If you see the versions of Node.js and npm displayed in the terminal, it means that Node.js has been installed successfully on your system.

Conclusion

Congratulations! You have now successfully installed Node.js on your Ubuntu system. You can start building powerful server-side applications using JavaScript and take advantage of the vast ecosystem of Node.js libraries and frameworks.
