How to Update Node.js: Safely Upgrading to the Latest Stable Version

Introduction

Keeping Node.js updated is important for getting the recent features, performance increases, and security fixes. Regular updates remove vulnerabilities and make sure that your application runs without an issue. But the question remains: how to update NodeJS safely without breaking existing setups?

Updating Node.js involves knowing the right tools and methods, like NVM, Homebrew, or package managers. This guide will show you the best ways to update Node.js while keeping your development environment intact.

And thinking about removing Node.js from your system? Then hire NodeJS developers to assist with your web app development!

Preparing for the Update

Before starting the update, you should back up your current Node.js applications. Now then, you won’t lose important data in case something goes wrong. Also, ensure your development environment is stable and that you’re not working on a major project.  This precaution can save you time if anything needs to be rolled back.

To update Node.js easily, use NVM (Node Version Manager). It helps you manage and switch between different Node.js versions, keeping your projects compatible.

Let’s update Node.js with NVM on Windows:

1. First off, go to the nvm-windows repository. Click on the “Download Now!” button to get the NVM utility.
2. After the download completes, install the .exe file of the recent release after selecting ‘nvm-setup.exe’.
3. Open the file that is downloaded & follow the instructions in the installation wizard to complete the setup correctly.

To confirm that NVM has been installed correctly, open your terminal and run:

nvm-v

This command should display the NVM version installed.

Managing Node.js Versions Using NVM:

Once NVM is installed, you can start installing, uninstalling, and switching between different Node.js versions with the following commands:

• To install a particular version of Node.js, run:

nvm install node-version

For example:

nvm install 16.16.0

This will install the specified version. After installation, you can switch to that version by using:

nvm use node-version

For instance:

nvm use 16.16.0

Considering the impact of NodeJS developers in real-time web app development, keeping your environment updated is crucial for maintaining optimal performance.

• To uninstall a version of Node.js that is no longer needed, use:

nvm uninstall node-version

For example:

nvm uninstall 16.16.0

• To see all the installed Node.js versions on your system, run:

nvm list

This command shows all the Node.js versions installed on your system, letting you switch between them easily. With NVM, you can keep multiple Node.js versions and ensure compatibility for different projects, making it great for managing environments with varying version requirements.

Conclusion

Now, do you understand why it is important to know how to update NodeJS? It is important because by updating it we can maintain a very safe and efficient development environment. You can easily keep Node.js updated and access the latest features using NVM, Homebrew, or package managers.
