🎯 Tailwind CSS v4 + Vite + React Setup (The Clean Way)

If you're starting with Tailwind CSS v4, you might’ve noticed:
most tutorials and videos are still stuck in the old version. I faced it too—docs didn’t help much, and outdated commands like tailwindcss inithad me completely lost.

So here’s the step-by-step setup that finally worked for me:

✅ Tailwind v4 Setup with React + Vite

1. Create your Vite + React project:
   npm create vite@latest my-app -- --template react
cd my-app

2. Install Tailwind CSS v4 with Vite plugin:
   npm install -D tailwindcss@latest @tailwindcss/vite

3. Create and edit src/index.css:
   @import "tailwindcss";

4. Update vite.config.js:
   

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'
import tailwindcss from '@tailwindcss/vite'

export default defineConfig({
  plugins: [react(), tailwindcss()],
});

1. Make sure main.jsx imports ./index.css

2. Test it in App.jsx:
   

function App() {
  return (
    <h1 className="text-4xl font-bold text-blue-600">
      Hello Tailwind v4!
    </h1>
  );
}

1. Run your dev server: npm run dev

✅ And you’re all set with Tailwind v4 running in your React app using Vite!
