How do I update Node.js?

 

Guidelines To Update Node.js:

Introduction

  1. Node.js is a powerful, open-source runtime environment for running JavaScript on the server side. Keeping Node.js updated ensures you’re benefiting from the latest features, bug fixes, security patches, and performance improvements. In this guide, we’ll walk you through the process of updating Node.js on different operating systems.

1. Check Your Current Node.js Version

Before updating, it’s good to know which version of Node.js is currently installed. To check, open your terminal or command prompt and run:

node -v

The output will display the version number, like v16.15.0.

2. Methods to Update Node.js

There are several ways to update Node.js depending on your operating system and personal preference.

Using Node Version Manager (NVM)

NVM is one of the most popular tools for managing multiple Node.js versions on the same system.

Steps for Linux/MacOS Users:

1. Install or update NVM (if not installed):

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash

2. Reload your shell configuration file:

source ~/.bashrc # Or ~/.zshrc for Zsh users

3. Install the desired Node.js version:

nvm install <version>

Replace <version> with the version number (e.g., 18.17.0) or use nvm install –lts for the latest long-term support version.

4. Set the default version:

nvm alias default <version>

For Windows Users:

1. Install nvm-windows.

2. Follow the same steps to install and manage Node.js versions as above using the nvm command.

Updating via Package Manager

If you installed Node.js through a package manager, you can update it using the same tool.
