Node.js is a cross-platform JavaScript runtime built on Chrome’s V8 engine that lets you run JavaScript outside the browser. It powers everything from REST APIs and microservices to full-stack web applications and CLI tools. Node.js 22 LTS (codename “Jod”) is the current long-term support release, maintained through April 2027.<\/p>\n\n\n\n
This guide covers three methods to install Node.js 22 LTS on Ubuntu 24.04 and Debian 13 – the NodeSource repository (recommended for production), default apt packages, and nvm for managing multiple versions. We also cover npm and yarn package management plus firewall configuration for Node.js applications.<\/p>\n\n\n\n
The NodeSource<\/a> repository provides the latest Node.js 22 LTS builds packaged for Debian-based systems. This is the recommended method for production servers since you get timely security updates through apt.<\/p>\n\n\n\n First, update your package index and install the required dependencies:<\/p>\n\n\n\n Download and run the NodeSource setup script for Node.js 22:<\/p>\n\n\n\n The script adds the NodeSource GPG signing key and configures the apt repository. You should see confirmation that the repository was added successfully:<\/p>\n\n\n\n Now install Node.js 22 LTS:<\/p>\n\n\n\n Verify the installation by checking the Node.js and npm versions:<\/p>\n\n\n\n The output confirms Node.js 22 LTS is installed:<\/p>\n\n\n\n Check the bundled npm version:<\/p>\n\n\n\n npm ships bundled with Node.js – you should see version 10.x or later:<\/p>\n\n\n\n Ubuntu 24.04 and Debian 13 include Node.js in their default repositories. The version may be older than the latest Node.js 22 LTS, but this method requires no external repositories.<\/p>\n\n\n\n Install Node.js and npm from the default repos:<\/p>\n\n\n\n Check the installed version:<\/p>\n\n\n\n The default repository version is typically older than NodeSource. If you need the latest Node.js 22 LTS features, use Method 1 (NodeSource) or Method 3 (nvm) instead.<\/p>\n\n\n\n nvm lets you install and switch between multiple Node.js versions on the same machine. This is ideal for development environments where different projects need different Node.js versions. If you need to run multiple versions of Node.js<\/a> side by side, nvm is the right tool.<\/p>\n\n\n\n Download and run the nvm install script (v0.40.4 at the time of writing):<\/p>\n\n\n\n The script clones the nvm repository to Verify nvm is working:<\/p>\n\n\n\n You should see the nvm version number confirmed:<\/p>\n\n\n\n Install Node.js 22 LTS using nvm:<\/p>\n\n\n\n nvm downloads and installs the latest Node.js 22 release along with npm:<\/p>\n\n\n\n Set Node.js 22 as the default version for new shell sessions:<\/p>\n\n\n\n Confirm the active version:<\/p>\n\n\n\n npm is the default package manager for Node.js. It handles dependency installation, script execution, and package publishing. Here are the essential npm operations you need to know.<\/p>\n\n\n\n Create a new project directory and initialize it with a The Local packages are installed in the project’s For development-only dependencies like testing frameworks or linters:<\/p>\n\n\n\n Global packages provide CLI tools available system-wide. Use global installs sparingly – only for tools you run from the command line, not project dependencies:<\/p>\n\n\n\n List all globally installed packages:<\/p>\n\n\n\n The output shows the globally installed packages and their versions:<\/p>\n\n\n\n Update all packages in a project to their latest compatible versions:<\/p>\n\n\n\n Remove a package:<\/p>\n\n\n\n Check for outdated packages:<\/p>\n\n\n\n Audit your dependencies for known security vulnerabilities:<\/p>\n\n\n\n Yarn is an alternative package manager that some projects prefer for its speed and deterministic installs. Node.js 22 ships with Corepack, which manages Yarn without a separate install step.<\/p>\n\n\n\n Enable Corepack to activate Yarn:<\/p>\n\n\n\n Verify Yarn is available:<\/p>\n\n\n\n The version output confirms Yarn is ready to use:<\/p>\n\n\n\n To use Yarn 4 (Berry) in a project, set the version inside the project directory:<\/p>\n\n\n\n Basic Yarn commands mirror npm closely:<\/p>\n\n\n\n If your Node.js application serves traffic, you need to open the appropriate port in the firewall. Ubuntu 24.04 and Debian 13 use UFW (Uncomplicated Firewall).<\/p>\n\n\n\n For a typical Node.js app running on port 3000:<\/p>\n\n\n\n If your app uses port 8080:<\/p>\n\n\n\n Enable UFW if it is not already active:<\/p>\n\n\n\n Verify the firewall rules are in place:<\/p>\n\n\n\n The output shows the allowed ports and their status:<\/p>\n\n\n\n For production deployments, run your Node.js app behind a reverse proxy like Nginx<\/a> rather than exposing the Node.js port directly. The reverse proxy handles SSL termination, load balancing, and static file serving. You can pair it with a process manager like PM2 to keep your app running across restarts.<\/p>\n\n\n\n To confirm everything works end to end, create a simple HTTP server. Create a file called Add the following code:<\/p>\n\n\n\n Start the server:<\/p>\n\n\n\n The server starts listening on port 3000:<\/p>\n\n\n\n Open a second terminal and test with curl:<\/p>\n\n\n\n You should get back the response confirming Node.js is working:<\/p>\n\n\n\n Press If you installed Node.js via NodeSource or the default repos and need to remove it:<\/p>\n\n\n\n If you used nvm, uninstall the Node.js version and optionally remove nvm itself:<\/p>\n\n\n\n Node.js 22 LTS is now installed on your Ubuntu 24.04 or Debian 13 system. The NodeSource repository gives you the latest stable releases with standard apt updates, while nvm is better suited for development machines where you juggle multiple Node.js versions. You can also manage containers for your Node.js apps – see how to install Docker on Ubuntu<\/a> for container-based deployments.<\/p>\n\n\n\n For production deployments, put your Node.js app behind Nginx as a reverse proxy, use PM2 as a process manager, and enable SSL with Let’s Encrypt. Monitor your application logs and set up SSH access<\/a> for secure remote management.<\/p>\n","protected":false},"excerpt":{"rendered":" Node.js is a cross-platform JavaScript runtime built on Chrome’s V8 engine that lets you run JavaScript outside the browser.
