Guide to Node.js Installation on Ubuntu 22.04

Node.js is a popular open-source JavaScript runtime built on Chrome's V8 JavaScript engine. It allows you to build scalable and high-performance server-side applications using JavaScript. This guide will walk you through the installation process of Node.js on Ubuntu 22.04.

Prerequisites

  • A system running Ubuntu 22.04
  • A user account with sudo privileges
  • An internet connection

Installation Steps

  • Begin by updating your apt repository to ensure you have the latest package information and dependencies. Open a terminal and run the following command:
sudo apt update

This command will refresh the package lists and update any outdated packages on your system.

  • Install the curl utility if it's not already installed. curl is used to transfer data to or from a server using various protocols. Execute the following command in the terminal to install it:
sudo apt install curl

This command will download and install curl from the Ubuntu repositories.

  • Now, you can proceed with the installation of Node.js. Run the following command in the terminal to download and execute the Node.js setup script: (replace "version" with the version you want to install, e.g. 18)
curl -fsSL https://deb.nodesource.com/setup_version.x | sudo -E bash -

This command fetches the setup script from the NodeSource repository and pipes it to the bash shell with elevated privileges (sudo), allowing it to modify system files.

  • Once the setup script has been executed, you can install Node.js by running the following command:
sudo apt install -y nodejs

This command installs Node.js and its package manager, npm, using the package manager apt.

  • After the installation is complete, you can verify the Node.js and npm versions by running the following commands:
node --version
npm --version

You should see the version numbers of Node.js and npm printed in the terminal, indicating a successful installation.

Finished

Congratulations! You have now installed Node.js on your Ubuntu 22.04 machine. Node.js is ready to be used for developing your JavaScript applications.
