How to Install React: Step-by-Step Guide

Make sure you have the latest version of Node.js and npm installed. You can download Node.js from: https://nodejs.org

Step 1: Check Node.js and npm Version

Open your terminal or command prompt and type:

node -v

If it returns version numbers, you're good to go!

Step 2: Install React Using Vite (Fastest Method)

React apps used to be created with create-react-app, but in 2025, Vite is the modern and faster alternative. Run the following command:

npm create vite@latest my-react-app -- --template react

Or using yarn:

yarn create vite my-react-app --template react

This will scaffold a new React project named my-react-app.

Step 3: Move Into Your Project Directory

cd my-react-app

Step 4: Install Dependencies

npm install

Step 5: Run Your React App

npm run dev

Now open your browser and go to http://localhost:5173/. 🎉 You'll see your React app running!
