How to Downgrade Node Version 21.5.0 or 20.10.0 LTS

Software downgrading may be just as difficult as updating it, but not with NVM. This utility makes switching Node.js versions simple.

To downgrade Node.js to a specific version, you can use a version manager like nvm (Node Version Manager) or n (Node version manager). I’ll provide instructions for NVM, as it’s a popular choice.

What is Node?

What is Node

Node is an open-source, cross-platform JavaScript runtime environment that allows developers to execute JavaScript code outside of a web browser. It is also known as Node.js. Node.js was created in 2009 by Ryan Dahl and is based on the V8 JavaScript engine, which runs the Google Chrome browser.

Key features and aspects of Node.js include:

  • Asynchronous and Event-Driven: One of the defining characteristics of Node.js is its asynchronous, non-blocking I/O model. This enables handling multiple connections simultaneously without the need for multi-threading, making it well-suited for scalable network applications.
  • JavaScript Everywhere: Node.js allows developers to use JavaScript for both server-side and client-side programming, creating a unified development environment. This facilitates the sharing of code and knowledge between server and client applications.
  • NPM (Node Package Manager): Node.js comes with a package manager called npm, which is one of the largest ecosystems of open-source libraries. Developers can easily install, share, and manage third-party packages and dependencies using npm.
  • Server-Side Development: Node.js is commonly used for server-side development to build scalable and high-performance web applications. It is often employed for building APIs, handling HTTP requests, and managing server-side logic.
  • Real-Time Applications: Node.js is well-suited for building real-time applications such as chat applications, online gaming, and collaborative tools due to its event-driven architecture and support for WebSockets.
  • Cross-Platform: Node.js is designed to be cross-platform, which means it can run on various operating systems, including Windows, macOS, and Linux.

Node.js has grown in popularity in the development community, and it is still frequently used for developing a wide range of applications, from small-scale projects to large-scale business systems. Because of its adaptability and efficiency, it is an excellent choice for current web development.

What is Downgrading Node version?

What is Downgrading Node version

Downgrading Node.js version refers to the act of installing and switching to a lower or older version of the Node.js runtime on your computer. This might be required for a variety of reasons, including:

  • Compatibility: Your project may require a specific Node.js version to work correctly with certain dependencies or frameworks.
  • Legacy Code: If you are working on an older project that was developed with an earlier Node.js version, you might need to downgrade to run that code.
  • Package Compatibility: Some npm packages or modules may not be compatible with the latest Node.js version, so downgrading can be a solution.
  • Testing and Development: Developers often need to test their applications on different Node.js versions to ensure compatibility and identify potential issues.

You may use a version manager such as nvm (Node Version Manager) or n (Node Version Manager) to downgrade Node.js. These utilities make it simple to switch between Node.js versions and manage the versions installed on your machine.

Downgrading usually entails installing the desired Node.js version and making it the active version. After downgrading, make sure that the transition was successful and that your project still works with the previous Node.js version.

How to Downgrade Node Version

To downgrade to a previous version of Node.js, you can use a version manager like nvm (Node Version Manager). Here are the steps to downgrade Windows, macOS, and Linux Node.js using nvm:

Using nvm (Node Version Manager):

Using nvm (Node Version Manager)

  1. Install nvm: If you don’t have nvm installed, you can install it by following the instructions on the official GitHub repository.
  2. List installed Node.js versions: Open a terminal and run the following command to see the list of Node.js versions installed on your machine:
    nvm ls
  3. Choose a version: Identify the version you want to switch to and note its version number.
  4. Install the desired version: Use the following command to install a specific Node.js version:
    nvm install <version_number>

    Replace <version_number> with the actual version number you want to install.

  5. Switch to the installed version: Once the installation is complete, set the desired version as the default using the following command:
    nvm use <version_number>

    Replace <version_number> with the version number you installed.

  6. Verify the version: Check if the Node.js version has been switched successfully:
    node -v

    This should display the version you just installed.

That’s it! You have successfully downgraded your Node.js version using nvm. Keep in mind that you might need to restart your terminal or open a new terminal window for the changes to take effect.
