A Comprehensive Guide to Updating NodeJS Using NVM (Node Version Manager)

NodeJS, the robust server-side JavaScript runtime, often rolls out new versions with improved features, bug fixes, and enhanced performance. To benefit from these updates, it’s essential to keep NodeJS updated. One of the best tools for this task is NVM, short for Node Version Manager.

What Makes NVM Unique?

Flexibility is a hallmark feature of NVM. This tool not only facilitates seamless updates to the latest NodeJS version but also empowers users to effortlessly oversee and transition between various NodeJS versions.

  • Independence: No need to rely on the system’s default package manager. NVM offers an independent route to manage NodeJS versions;
  • Customizability: You can select specific versions, making it easy to test applications with different NodeJS releases.

Initial Steps Before Updating NodeJS via NVM

Before diving into the actual update process, ensure that your system’s package lists are synchronized with their sources:

$ sudo apt update

This command fetches all the upgradable packages, setting the stage for a seamless update.

Step-by-Step Guide to Update NodeJS Using NVM:

Installing NVM via curl

Instead of fetching NVM from package repositories, it’s often installed directly using the curl method:

$ curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

At this point, NVM should be on your Linux machine.

To confirm the installation of NVM, it’s imperative to refresh the terminal beforehand. You have two viable options to achieve this:

Utilize the ‘source’ command as follows:

$ source ~/.bashrc

Alternatively, you can opt for a straightforward approach by closing the current terminal session and subsequently reopening it.

Once the terminal has been refreshed, proceed to validate the successful NVM installation by inspecting its version:

$ nvm --version

Ensure to execute these steps meticulously to ascertain the proper functioning of NVM.

$ nvm --version

Identify Currently Installed NodeJS Version

Before updating, it’s always a good practice to identify the current NodeJS version. This assists in maintaining version control and making informed decisions about the update:

$ nvm ls

Displaying the Array of NodeJS Versions Ready for Updating

A standout feature of NVM lies in its ability to present a comprehensive array of accessible NodeJS versions, encompassing the archaic iterations as well as the latest and most cutting-edge releases. To peruse this comprehensive list, simply execute the following command:

$ nvm ls-remote

Once you pinpoint the specific version that aligns with your requirements, which is often the most recent stable iteration, take note of its version number.

Initiating the Installation and Update Process for Your Chosen NodeJS Version

Armed with the version number of your preference, proceed to utilize the installation command. This command serves a dual purpose, enabling you to not only download but also seamlessly transition to the chosen NodeJS version:

$ nvm install [version_number]

For instance, to update to version 19.8.1:

$ nvm install 19.8.1

With the steps outlined above, NodeJS is now updated on your machine. While NVM remains a top method for this process, there are alternative routes to explore. Stick around to delve into other strategies to manage and update NodeJS.

How to Update Node.js Using NPM (Node Package Manager)

NPM, which stands for Node Package Manager, plays a pivotal role as a versatile utility within the Node.js ecosystem. Its role extends beyond just overseeing the various iterations of Node.js; it empowers users to effortlessly install, update, and uninstall Node.js packages. Whether you’re looking to keep your Node.js installation up-to-date or keen on delving into the latest enhancements, NPM emerges as the ultimate preference. This comprehensive guide unveils the steps to efficiently upgrade your Node.js via the remarkable NPM tool.

Preparation: Clearing the NPM Cache

Before diving into the actual update process, ensuring a smooth path is crucial. Begin by cleaning out the NPM cache to prevent any unwanted errors.

Command to Execute:

$ sudo npm cache clean -f

What does it do?

sudo: Grants administrator privileges.

-f: Forces a clear cache operation.

Outcome:

Upon executing, the NPM cache will be cleared, setting the stage for the subsequent steps.

Step 1: Introducing Node’s Version Manager – “n”

The Node.js update through NPM requires the installation of a version manager called “n”.

Command to Execute:

$ sudo npm install -g n

What is the significance of this? 

Employing a version manager offers a seamless transition between various iterations of Node.js, simplifying the process of updating or downgrading as needed. 

As a next step, prioritize stability by upgrading to the most recent stable release of Node.js.

For a seamless Node.js experience without unexpected bugs or issues, it’s wise to install the most recent stable version.

Command to Execute:

$ sudo n stable

Key Insights:

  • Stable versions undergo extensive testing, ensuring minimal errors;
  • It’s advisable to lean towards stable versions for production environments.

Adventure Awaits: Installing the Latest (Yet Unstable) Version of Node.js

For the enthusiasts eager to try out the newest Node.js features (with an acceptance of potential bugs), the latest version beckons.

Command to Execute:

$ sudo n latest

Points to Note:

  • At a certain point, the stable version was 18.15.0. However, with the ‘latest’ tag, one might end up with a version like 19.8.1;
  • Using the ‘latest’ tag introduces users to the bleeding-edge features of Node.js, though stability isn’t guaranteed.

Customized Updates: Manually Selecting a Specific Node.js Version

Sometimes, the need arises to install a particular version of Node.js, whether to sidestep compatibility issues or address other concerns.

Command to Execute:

$ sudo n 19.8.1

Conclusion

In conclusion, updating your Node.js version on Ubuntu is a crucial task for any developer or system administrator. Node.js continues to evolve, offering improved performance, security enhancements, and access to the latest features and libraries. By following the steps outlined in this article, you can ensure that your Node.js environment is up-to-date and optimized for your projects.

Keep in mind that staying current with Node.js versions not only benefits your applications but also helps you stay in sync with the broader developer community. As new releases become available, developers can leverage the latest capabilities, fix compatibility issues, and take advantage of enhanced performance, ultimately leading to more robust and efficient web applications.
