Introduction

Setting Up a Project

You need Node.js installed. Then create a project with Vite, a fast build tool:

npm create vite@latest my-app -- --template react
cd my-app
npm install
npm run dev

Open the address it prints (usually http://localhost:5173). Edit src/App.jsx and the page updates instantly.

Project structure

File	Purpose
`index.html`	The single HTML page
`src/main.jsx`	Starts React and renders `<App />` into the page
`src/App.jsx`	Your root component
`package.json`	Project info and dependencies
