A Short Introduction to NPM

Node Package management, or NPM, is a package manager for JavaScript. 

It includes Node.js, a runtime environment for executing JavaScript code outside a web browser. 

NPM has evolved into a critical tool in the JavaScript ecosystem, allowing developers to take advantage of the vast JS package ecosystem to streamline the development process. 

Here are a few NPM characteristics that make it such a powerful JS development component:

Package Management 

NPM simplifies installing, managing, and updating Node.js packages and dependencies. It offers access to a large and mature ecosystem of open-source packages you can use in your apps.

Command Line Interface

NPM includes a command-line interface (CLI) that allows you to communicate with the package management. You can manage packages using npm install, update, and uninstall commands.


NPM keeps track of your project’s dependencies, scripts, and other metadata in a file called package.json. This file acts as a manifest for your project and lets you specify the required packages and dependencies.

Easy Version Naming 

NPM employs semantic versioning, consisting of three integers separated by dots (1.2.3). These numbers denote the major, minor, and patch versions. You may define version ranges for your dependencies using NPM, allowing you control over which versions to install.

Support for Custom Scripting

In the package.json file, developers may define custom scripts. These scripts may be launched using the NPM CLI to automate basic operations like running tests, creating assets, launching a development server, and more.

Huge Package Registry

The npm Registry is NPM’s default registry, which holds millions of packages. If necessary, you can also create private registrations or use other registrars.

NPM is a powerful tool for managing JavaScript packages and dependencies in your Node.js projects. It simplifies integrating third-party code into your applications and helps ensure your project remains up-to-date and secure.

After that brief introduction to NPM, let’s discuss the various options for installing Node.js on an Ubuntu machine.

Before trying out any of the three methods, you need a Ubuntu 22.04 server and a non-root account with sudo privileges. 


Three Ways You Can Install Node.js on Ubuntu 22.04

Installing Node.js on Ubuntu 22.04 is a very flexible process, and you can opt for several methods to carry out the installation. Let’s discuss three ways to install Node.js on an Ubuntu 22.04 server easily. 

Method 1: Install Node.js From the Official Repository on Ubuntu 22.04

The default Ubuntu repositories include Node.js and npm. As a result, you can easily install them using the APT package manager. 

Start by updating the Ubuntu package index with the following command:

# apt update

Next, install Node.js and NPM with the following command. The APT package manager will download and unpack the involved packages.

# apt install nodejs npm -y


Once the installation finishes, we recommend checking the Node.js installation by printing out the version information:

# node -v


Method 2: Install a Specific Node.js Version with NodeSource

The method mentioned above installs the Node.js version in the official Ubuntu repository.

However, if you wish to install a different Node.js version on Ubuntu 22.04 server, you can use a PPA supplied by NodeSource to install a different version of Node.js. These PPAs have more Node.js versions than the official Ubuntu repository. 

As of this writing, Node.js v14, v16, and v18 are all accessible.

To demonstrate the method, we’ll install Node.js version 20.x. You can install other versions, such as 18 or 19, using this method. 

Start with the following curl command that gets the desired repository from NodeSource:

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


The PPA from NodeSource will be added to the settings, and your local package cache will be automatically updated. 

Start the installation process by calling up the setup script in the terminal. 

# bash nodesource_setup.sh 


Next, install Node.js with the following command: 

# apt install nodejs

Once the process finishes, you can verify the installation by printing the version details. 

# node -v


Method 3: Install Node.js and NPM Using NVM

If you have multiple Node.js versions on your server, you can use Node Version Manager or NVM to manage these versions. 

You can use NVM to install NodeJS and NPM on your machine.

Start by taking a look at the following script:  

# curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh


  • To download and install NVM, run the following script:

# curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash


Next, run the following commands to load NVM: 

# export NVM_DIR="$HOME/.nvm"

# [ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

# [ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"

Once these commands finish, NVM will be installed on your server. Next, check the version: 

# nvm -v


Now, to install the available versions, use the following command: 

# nvm ls-remote


Install the latest Node.js version with the following command:

# nvm install node


Include the version number in the command if you wish to install a specific version. For instance, if you wish to install version 17.1.0, you can use the following command with the version: 

# nvm install v17.1.0

Use NPM to Simplify Node.js Management on Ubuntu 22.04

Experts advise installing NPM alongside Node.js because NPM simplifies the management of the Node.js service. For instance, you can use the following NPM commands to manage the interaction with the packages: 

  • npm ls: List the installed packages to see whether you need to install something before running it.
  • npm run-script: Executes a given script.
  • npm start: Launches a package.
  • npm stop: Terminates the execution of a package.
  • npm restart: Restarts a package. This kicks off the stop-start cycle for the package.

How to Secure Node.js?

Unfortunately, Node.js provides a powerful scripting engine that is easy to abuse. That’s why installing Node.js without following the recommended practices is a surefire invitation for cyberattacks.

Securing a Node.js application involves implementing various best practices and security measures. Here are some crucial steps to secure a Node.js application:

  1. The root user(s) should not launch Node.js service: Running code as the root user gives any hacker an excellent resource for disassembling everything else. We highly recommend launching Node.js with only the required permissions for the application.
  2. Update dependencies: Regularly update your application’s dependencies, including the Node.js runtime and external libraries. This is essential for closing off any vulnerabilities in dependencies that you might overlook in a manual patching or update process. 
  3. Use robust authentication: Your application’s first line of defense is to guarantee that the user is not a hacker. It is best to utilize a solution like Authenticator or SecureAuth for authentication.
  4. Use a reverse proxy: A reverse proxy is a type of web server that allows you to limit the number of requests a Node.js application may get. Essentially, the reverse proxy accepts the user request, validates it, and only then transmits it to the Node.js application.
  5. Set package access levels: One of the reasons for using package management like NPM is to regulate who can (and, more importantly, can’t) access packages. 
  6. Enable Transport Layer Security (TLS): Use HTTPS with a valid SSL/TLS certificate to encrypt communication between the client and server. This helps protect sensitive data from interception and tampering.
  7. Secure the production environment: Ensure that your production environment is properly secured. Restrict server access, turn off unnecessary services and ports, use secure SSH configurations, and monitor system logs for suspicious activities regularly. 

How to Remove Node.js from Ubuntu Server?

You can remove Node.js with apt or nvm depending on how you 

installed it.

If you used the APT to install it, use the apt remove command to remove the Node.js version from the system repositories:

# apt remove nodejs


By default, the apt remove command keeps any local configuration files. If you don’t wish to keep the configuration files, run the apt purge command:

# apt purge nodejs

If you used NVM to install Node.js, you should first establish if it is the currently active version:

# nvm current


Now, before installing the Node.js version, you need to deactivate it with the following command:

# nvm deactivate 


Finally, uninstall the currently active version with the following command: 

# nvm uninstall node_current_verion
