Updating Node.js on a Mac

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside of a web browser. It is widely used for building server-side applications, command-line tools, and other applications. Over time, Node.js releases new versions with bug fixes, security updates, and new features. Keeping your Node.js version up to date is important for security and stability.

In this article, we will explain how to update Node.js to a specific version on a Mac using several methods.

Method 1: Using NVM (Node Version Manager)

NVM (Node Version Manager) is a tool that allows you to manage multiple Node.js versions on a single machine. It provides a simple and flexible way to switch between different Node.js versions and manage dependencies.

1. Install NVM: To install NVM, open a terminal window and run the following command:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.2/install.sh | bash

2. Load NVM: Load NVM into your shell by running the following command in your terminal window:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"  # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"  # This loads nvm bash_completion

3. List available Node.js versions: You can list all available Node.js versions by running the following command:

nvm ls-remote

4. Install a specific Node.js version: To install a specific version of Node.js, run the following command, replacing [version] with the desired version number:

nvm install [version]

5. Use a specific Node.js version: To use a specific version of Node.js, run the following command, replacing [version] with the desired version number:

nvm use [version]

Method 2: Using Homebrew

Homebrew is a package manager for MacOS that makes it easy to install and manage software packages. It also provides a convenient way to update Node.js.

1. Install Homebrew: To install Homebrew, open a terminal window and run the following command:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

2. Install Node.js: To install Node.js using Homebrew, run the following command:

brew install node

3. Update Node.js: To update Node.js to the latest version using Homebrew, run the following command:
