Your Comprehensive Guide to Installing NPM on Ubuntu 24.04

Are you looking to enhance your backend development using JavaScript? The Node Package Manager (NPM) is essential for managing JavaScript packages, and its installation on Ubuntu 24.04 can be done effortlessly. This detailed guide will walk you through two robust methods for installing NPM, ensuring you are well-equipped to manage your Node.js projects efficiently. Read on to discover the steps and tips for leveraging NPM optimally!

Understanding the Basics: What is NPM?

NPM stands for Node Package Manager and is a vital tool for JavaScript developers. It not only allows you to install and manage packages but also helps in maintaining dependencies in your Node.js applications. To embark on your journey, the first step is to install Node.js on your system since NPM comes bundled with it.

Why Choose Ubuntu 24.04 for Your Node.js Development?

Ubuntu 24.04 is a user-friendly Linux distribution that provides a stable environment for both beginners and experienced developers. The ease of package management and extensive community support make it an ideal choice for running Node.js applications.

Method 1: Install NPM on Ubuntu 24.04 via APT

If you prefer simplicity and don’t require a specific version of Node.js, using the default Ubuntu repository is the easiest method to install both Node.js and NPM. Follow these steps:

1. First, update your package list:

$ sudo apt update

2. Next, install Node.js:

$ sudo apt install nodejs

3. To check that Node.js is installed correctly, verify its version:

$ node -v

4. Finally, install NPM with the command:

$ sudo apt install npm

5. To confirm NPM installation, check its version:

$ npm -v

Congratulations! You now have Node.js and NPM installed on your Ubuntu 24.04 system, ready for programmatic tweaks and package management!

Method 2: Install NPM Using NodeSource PPA

If your project requires a specific version of Node.js, using the NodeSource PPA (Personal Package Archive) is the most efficient way to ensure you have the correct setup without unnecessary hassle:

1. First, visit the Node.js website to decide which version suits your needs.
2. Use curl to download the setup script, as shown below (this example uses version 20.x):

$ curl -sL https://deb.nodesource.com/setup_20.x -o nodesource_setup.sh

3. After downloading, view the script to confirm legitimacy:

$ nano nodesource_setup.sh

4. Run the script with:

$ sudo bash nodesource_setup.sh

5. If you previously installed Node.js using APT, uninstall it to avoid conflicts:

$ sudo apt autoremove nodejs npm

6. Now, install Node.js (including NPM) from the NodeSource repository:

$ sudo apt install nodejs

7. To verify the installations, check the versions:

$ node -v

$ npm -v

By using the NodeSource PPA, you benefit from NPM versions that may be more current than those available through the default repository.

Conclusion

With these two comprehensive methods for installing NPM and Node.js on Ubuntu 24.04, you can easily manage your backend applications. Whether you choose to use the APT method for simplicity or the NodeSource PPA for targeted version control, both options facilitate effective package management for your projects.
