If you want to Install Node.js Ubuntu systems for web development or backend applications, Ubuntu 20.04 offers several reliable installation methods. Node.js is widely used for building scalable APIs, real-time applications, and modern JavaScript services, while npm helps developers manage packages and dependencies efficiently.
Whether you are a beginner setting up your first server or a developer managing multiple Node.js versions, Ubuntu makes the process straightforward.
Node.js allows JavaScript code to run outside the browser, making it ideal for backend development and automation tasks. Many popular frameworks, including Express.js and Next.js, depend on Node.js.
Installing Node.js on Ubuntu provides several advantages:
Depending on your workflow, you can choose between NodeSource repositories, NVM, or Ubuntu’s default packages.
One of the most recommended methods is using the official NodeSource repository. This option provides newer and actively supported Node.js releases compared to Ubuntu’s default packages.
Start by updating your system and installing required dependencies:
sudo apt updatesudo apt install ca-certificates curl gnupg
Next, import the NodeSource GPG key:
sudo mkdir -p /etc/apt/keyringscurl -fsSL https://deb.nodesource.com/gpgkey/nodesource-repo.gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/nodesource.gpg
Add the NodeSource repository for Node.js 20:
NODE_MAJOR=20echo "deb [signed-by=/etc/apt/keyrings/nodesource.gpg] https://deb.nodesource.com/node_$NODE_MAJOR.x nodistro main" | sudo tee /etc/apt/sources.list.d/nodesource.list
Finally, install Node.js and npm:
sudo apt updatesudo apt install nodejs
Verify the installation:
node --versionnpm --version
Developers who need multiple Node.js versions often prefer NVM (Node Version Manager). It allows quick switching between versions without affecting the entire system.
Install NVM using:
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash
After restarting the terminal, verify the installation:
nvm --version
Install the latest Node.js release:
nvm install node
You can also install specific versions:
nvm install 20nvm install 18
Switch between versions easily:
nvm use 20
This method is especially useful for testing applications across multiple Node.js environments.
Ubuntu 20.04 also includes Node.js packages in its default repositories. However, the available version is older and no longer recommended for production workloads.
Install it with:
sudo apt updatesudo apt install nodejs npm
While simple, this approach is best suited for lightweight testing environments rather than modern production deployments.
Choosing the right way to Install Node.js Ubuntu systems depends on your development needs. NodeSource offers stable and updated packages, while NVM provides maximum flexibility for developers handling multiple Node.js versions. Although Ubuntu’s default repositories are easy to use, newer Node.js releases are better suited for secure and production-ready applications.
