What is Node JS?

Node.js, often referred to simply as Node, is an open-source, cross-platform JavaScript runtime environment that allows developers to run JavaScript code outside of a web browser. It’s built on the Chrome V8 JavaScript engine, providing a fast and efficient runtime for executing JavaScript code. Node.js enables developers to build scalable and high-performance applications, particularly on the server side. With its event-driven architecture and non-blocking I/O model, Node.js is well-suited for handling asynchronous operations, making it ideal for building real-time web applications, APIs, and microservices. 

Additionally, Node.js comes with a vast ecosystem of modules and packages available through npm, the Node.js package manager, which further enhances its versatility and productivity for developers. Overall, Node.js empowers developers to write JavaScript code for both frontend and backend development, streamlining the development process and fostering code reusability across different layers of a web application.

Why Install Nodejs on Mac?

Step 3: Verify Node Installation

To confirm the successful Node installation on your macOS system, execute the following command in your terminal:

node -v //This command checks the version of the nodejs

Step 4: Update NPM version

Node.js does not update the npm version automatically.

Execute the provided command to update your npm version.

$ sudo npm install npm –global //Update the npm CLI client

Boom! Node.js is installed on your system. Sounds interesting, isn’t it? Let’s move it further. 

How to Install Nodejs Using “Homebrew”?

Homebrew, a free and open-source software package management system, handles the Node installation process on macOS and Linux. It places packages into their designated directories and their associated files within /usr/local .

Here’s how you can install Node JS on macOS using Homebrew. Follow these steps:

1. Install Homebrew: If you haven’t already installed Homebrew, you can do so by opening Terminal and executing the following command:

/bin/bash -c “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)”

2. Update Homebrew: It’s a good practice to ensure Homebrew is up to date before installing any packages. Run the following command:

brew update

3. Install Node on Mac: Once Homebrew is installed and updated, you can install Node Mac by running the following command:

brew install node

4. Verify Installation: After the installation is complete, you can verify that Node.js and npm (Node Package Manager) have been installed successfully by running:

node -v npm -v

These commands should display the installed versions of Node.js and npm, respectively.

Uninstalling Nodejs from Mac

Uninstalling Node.js from a Mac can be done using several methods. Here are a few options:

1. Using Homebrew (if installed via Homebrew):

• Open Terminal.
• Run the following command to uninstall Node.js:

brew uninstall node

• This command removes Node.js and npm installed via Homebrew.

2. Manual Removal:

• Open Terminal.
• Run the following command to remove npm (if it was installed separately):

sudo rm -rf /usr/local/{lib/node{,/.npm,_modules},bin,share/man}/{npm*,node*,man1/node*}

• Run the following command to remove Node.js itself:

sudo rm -rf /usr/local/lib/node_modules/npm

• Additionally, you may want to delete any global npm packages you’ve installed. 

You can list them using:

npm list -g –depth=0

And then manually remove each package you want to uninstall.

• Verify that Node.js and npm have been removed by running:

node -v npm -v

These commands should return an error indicating that the commands are not found, which confirms the removal.

3. Using a Node Version Manager (nvm):

• If you’ve installed Node.js using nvm, you can uninstall it by first uninstalling nvm itself and then manually removing any installed Node.js versions.
• To uninstall nvm, follow the instructions provided in the nvm documentation or run the appropriate uninstall command if you installed nvm via a package manager like Homebrew.
