Setup

Step 1: Install Node.js

Download the latest LTS version of Node.js from the official website.

Once installed, open your terminal (macOS/Linux) or Command Prompt (Windows), and verify the installation with the following commands:

$ node --version
v22.14.0

$ npm --version
v11.3.0

Your versions might differ slightly — that’s perfectly fine!

Step 2: Create a New React App

Navigate to the folder where you’d like to create your project:

$ cd path/to/your/folder

Run the following command to create a new React project with TypeScript:

$ npx create-react-app my-app --template typescript <your-project-name>

This will take a few minutes to install dependencies. Once complete, navigate into your project folder:

$ cd <your-project-name>

To start the development server, run:

$ npm run start

Your React app should now be running on http://localhost:3000.
