How to Install Node.js and NPM with macOS Terminal (zsh)

*Title: How to Install Node.js and NPM with macOS Terminal (zsh) | Step-by-Step Guide* *Description:* In this video, we will show you how to install Node.js and npm (Node Package Manager) on macOS using the Terminal with the `zsh` shell. Whether you're just starting with web development or you want to build scalable applications using JavaScript, having Node.js and npm installed on your Mac is essential. This step-by-step guide will help you install Node.js on macOS using Homebrew, one of the most popular package managers for Mac. We’ll also walk you through verifying your installation and running your first Node.js application. What You’ll Learn: *Installing Homebrew on macOS:* If you don’t have Homebrew installed, we’ll show you how to install it. Homebrew is a package manager that simplifies the installation of software on macOS, and it's one of the easiest ways to install Node.js. *Installing Node.js and npm Using Homebrew:* We’ll guide you through the installation process using Homebrew commands in your Terminal (zsh). Both Node.js and npm will be installed with one simple command. *Verifying Node.js and npm Installation:* After installation, we’ll show you how to check that both Node.js and npm are properly installed by running version checks in the Terminal. *Running Your First Node.js Program:* To ensure everything is working, we’ll create a simple "Hello, World!" Node.js program, run it from the Terminal, and confirm the output. Key Steps: 1. *Install Homebrew (if not already installed):* Homebrew is a package manager for macOS that makes it easy to install software. If you don’t already have it installed, open the Terminal and run the following command: ```bash /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Hom...)" ``` Once installed, update Homebrew: ```bash brew update ``` 2. *Install Node.js and npm Using Homebrew:* With Homebrew installed, you can install Node.js (which includes npm) by running the following command: ```bash brew install node ``` This command will install both Node.js and npm on your Mac, so you can start developing with JavaScript. 3. *Verify Installation:* After the installation is complete, verify that Node.js and npm are installed correctly by checking their versions: ```bash node -v ``` This will show the installed version of Node.js. Similarly, check the version of npm: ```bash npm -v ``` Both commands should return version numbers, confirming that Node.js and npm are installed. 4. *Running a Simple Node.js Program:* To make sure everything is set up correctly, we’ll create a simple Node.js program: Open your favorite text editor and create a file called `app.js`. Add the following code: ```javascript console.log("Hello, Node.js on macOS!"); ``` Save the file and return to the Terminal. In the Terminal, navigate to the directory where the `app.js` file is located and run the following command to execute the Node.js script: ```bash node app.js ``` If everything is set up correctly, you should see the message "Hello, Node.js on macOS!" printed in the Terminal. 5. *Installing Global npm Packages:* If you want to install npm packages globally, you can do so using the following command: ```bash npm install -g package-name ``` For example, to install `express`, a popular web framework for Node.js, run: ```bash npm install -g express ``` 6. *Optional - Updating Node.js and npm:* You can update Node.js and npm using Homebrew whenever a new version is released. Run the following commands to update: ```bash brew update brew upgrade node ``` Key Features: *Complete Installation Process:* From installing Homebrew to verifying Node.js and npm installations, we guide you through every step. *Beginner-Friendly:* Whether you're new to programming or just new to macOS, this guide is perfect for anyone looking to set up Node.js in a few simple steps. *Efficient Workflow:* Learn how to set up your development environment quickly and efficiently, allowing you to focus on building applications with Node.js. By the end of this tutorial, you’ll have Node.js and npm installed and ready to use on your Mac. You’ll also know how to write and run Node.js programs directly from the Terminal using `zsh`.
