Install Node.js Ubuntu 20.04 Using Easy Methods

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.

Why Install Node.js Ubuntu Systems?

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:

• Fast and scalable server-side development
• Large npm package ecosystem
• Cross-platform compatibility
• Strong community support
• Efficient asynchronous processing

Depending on your workflow, you can choose between NodeSource repositories, NVM, or Ubuntu’s default packages.

Install Node.js Ubuntu with NodeSource

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

Install Node.js Ubuntu Using NVM

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.

Using Ubuntu Repository Packages

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.

Conclusion

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.
