This guide provides a step-by-step walkthrough of installing TypeScript on your macOS machine.

How to Install TypeScript on macOS

Step 1: Install Node.js

You have two options for installing Node.js:

Option 1: Using the Installer

• Download Node.js: Visit the official Node.js website (https://nodejs.org) and download the latest Long Term Support (LTS) version for macOS.
• Run the Installer: Double-click the downloaded package file and follow the installation wizard.

Option 2: Using Homebrew

• Install Homebrew (if you don’t have it): Open Terminal and run the following command:

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

• Install Node.js LTS: In Terminal, run:

 brew install node@lts

• Add Node.js to PATH (if needed):
  • Open your shell configuration file (.zshrc or .bashrc) in a text editor.
  • Add the following line at the end of the file:

export PATH="/usr/local/opt/node@lts/bin:$PATH"

• Save the file.
• Restart Terminal or run source ~/.zshrc (or source ~/.bashrc).

Verify Node.js Installation:

• In Terminal, type node -v and press Enter. This should display the installed Node.js version.

node -v 

Step 2: Install TypeScript

• Open Terminal: If you closed it, open a new Terminal window.
• Install TypeScript Globally: Run the following command:

npm install -g typescript

• Verify TypeScript Installation:
  • In Terminal, type tsc -v and press Enter to display the installed TypeScript version.

Step 3: (Optional) Update TypeScript

To update to a newer version of TypeScript in the future, run:

npm update -g typescript

That’s it! You’ve successfully installed TypeScript on your macOS machine and are ready to start developing!
