Node.js is a free, open-source, cross-platform JavaScript runtime environment that can run on Linux, Windows, and macOS and is used to build server-side web applications. The top companies that favor Node.js are Netflix, Uber, PayPal, LinkedIn, and many more.

It offers various features such as asynchronization, scalability, cross-platform compatibility, a single-threaded event-driven loop, and support for JavaScript syntax.

In this article, I'll show you how to install Node.js and NPM on Ubuntu 24.04 using the default repository, NodeSource, and NVM. Aside from the first method, the other methods will allow you to install specific versions of Node.js and NVM.

Install Node.js and NPM on Ubuntu 24.04

The first method using the default repository is the simplest and most recommended for beginners, as it provides a stable (though not the latest) version of Node.js and NPM. However, if your work requires the latest or a specific version of Node.js and NPM, you can choose one of the other two NodeSource and NVM methods.

Method 1: Install Node.js and NPM Using Default Repository

1. Update the APT repository information using the following command:

$ sudo apt update


updating package database

2. Install Node.js and NPM from the default repository by running:

$ sudo apt install nodejs npm


installing nodejs and npm from default repository

3. After installation, you can run this command to check the version.

$ nodejs -v && npm -v


checking nodejs and npm version

As of now, Node.js v18 and NPM v9 are available from the default repository.

Method 2: Install Node.js and NPM Using NodeSource

This method involves adding the specific version of the Node.js NodeSource repository, then installing Node.js from the added repository. Before you follow this method, make sure that Node.js and NPM are not already installed on your system; if they are, ensure they are removed, and then follow these steps:

1. Install the required dependencies.

$ sudo apt install ca-certificates curl gnupg -y


install required dependencies for nodesource

2. NodeSource provides multiple custom scripts for different versions of Node.js, and you can find the supported versions for your system on their GitHub repo. For Ubuntu 24.04, the Node.js v22 script is available and can be added using the following command:

$ curl -fsSL | sudo -E bash -


running nodesource script

3. After running the script, you can now install Node.js (that includes NPM) corresponding to your chosen script (for now, it's v22).

$ sudo apt install nodejs


install nodejs from nodesource

4. Lastly, you can verify the version of Node.js and NPM by running:

$ nodejs -v && npm -v


checking the version of nodejs and npm installed from nodesource

This method will install NPM v10 in conjunction with Node.js v22.

Method 3: Install Node.js and NPM Using NVM

NVM (Node Version Manager) is a handy tool that allows you to seamlessly manage multiple Node.js versions concurrently without conflicts. This approach is particularly useful if you prefer using beta versions of Node.js alongside stable ones for production.

1. Run the following command to download the NVM installation script and install NVM at the specified destination.

$ curl | bash


running nvm script

2. Reloading the changes in your shell configuration file by running:

$ source ~/.bashrc


reloading the bash configuration file

You now have NVM installed on your Ubuntu 24.04 system.

3. To list all the available versions of Node.js, use the command below.

$ nvm list-remote


listing all nodejs versions

The command above will return a list of Node.js versions in the "vX.X.X" format, where you simply ignore the prefix "v" and make note of your desired "X.X.X" version.

4. Select your desired Node.js version for installation (let's say, "v18.11.0") and designate it in the following command:

$ nvm install 18.11.0


installing specific version of nodejs on ubuntu

5. Once the installation is complete, your desired Node.js version will be set as the default. Therefore, run the following command to list all installed Node.js versions:

$ nvm ls


listing all the installed nodejs version

6. I have only one version of Node.js installed, but if you've installed multiple versions, you can choose which one to keep as the default by specifying the Node.js version in the following command:

$ nvm use X.X.X

7. To avoid reverting to the previous default Node.js version in the next terminal session, simply execute the following command with your desired Node.js version:

$ nvm alias default X.X.X

Uninstall Node.js and NPM from Ubuntu 24.04

The removal process for Node.js and NPM varies based on the installation method you've selected. Nonetheless, I've included removal steps for all methods discussed in this article. Therefore, opt for the removal method corresponding to your chosen installation method.

Removing Node.js Using Default Repository

Just open your terminal and run the following command to remove Node.js and NPM:

$ sudo apt remove nodejs npm

Removing Node.js Using NodeSource

Run the following command to remove Node.js (which includes NPM), and then delete the NodeSourece repository added at the target location.

$ sudo apt purge nodejs && sudo rm -r /etc/apt/sources.list.d/nodesource.list && sudo rm -r /etc/apt/keyrings/nodesource.gpg

Removing Node.js Using NVM

First, run the following command to delete the NVM directory:

$ rm -rf "$NVM_DIR"

Open the "~/.bashrc" file, then find and delete the specified lines:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/" ] && \. "$NVM_DIR/" # This loads nvm
[[ -r $NVM_DIR/bash_completion ]] && \. $NVM_DIR/bash_completion

Here ends the article. For beginners, I recommend using the default repository to install Node.js and NPM, as it's more convenient for future updates. However, if you need to install multiple versions of Node.js and NPM, NodeSource and NVM are unbeatable options (by the way, I personally prefer NVM).
