npm and TypeScript Setup Guide for macOS

Follow these steps to install Node.js (which includes npm) and the TypeScript compiler on macOS.

Method 1: Using the Official Installer

1. Download Node.js:

   • Go to the official Node.js website: https://nodejs.org/
   • Download the LTS (Long-Term Support) version.
   • Command to open the website (optional, run in Terminal):

     open [https://nodejs.org/](https://nodejs.org/)

2. Install Node.js:

   • Run the downloaded .pkg installer and follow the on-screen instructions.

3. Verify Node.js and npm Installation:

   • Open Terminal (search for "Terminal" in Spotlight or find it in /Applications/Utilities/).

   • Run the following commands to check the installed versions:

     node -v

     Expected Output: A version number (e.g., v18.16.0)

     npm -v

     Expected Output: A version number (e.g., 9.5.1)

Method 2: Using Homebrew (Recommended)

1. Install Homebrew (if you don't have it):

   • Open Terminal and run:

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

     Follow the prompts to install Homebrew.

2. Install Node.js:

   • In Terminal, run:

     brew update
     brew install node

3. Verify Node.js and npm Installation:

   • In Terminal, run:

     node -v

     Expected Output: A version number (e.g., v18.16.0)

     npm -v

     Expected Output: A version number (e.g., 9.5.1)

Install TypeScript Compiler (for both methods):

1. Open Terminal and run the following command to install TypeScript globally:

   npm install -g typescript

2. Verify TypeScript Installation:

   • Run the following command to check the installed version of the TypeScript compiler:

     tsc -v

     Expected Output: A version number (e.g., Version 5.0.4)

Now you have npm and the TypeScript compiler installed on your macOS system.
