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

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

/* src/index.css */

Component Example

// src/components/Button.tsx
interface ButtonProps {
  variant?: 'primary' | 'secondary' | 'outline'
  size?: 'sm' | 'md' | 'lg'
  children: React.ReactNode
  onClick?: () => void

  )
}

Next.js

Setup (App Router)

# Create Next.js project (Tailwind included by default)
npx create-next-app@latest my-app
cd my-app

If adding to existing project:

npm install -D tailwindcss @tailwindcss/postcss

Configuration

// postcss.config.mjs
export default {
  plugins: {
    '@tailwindcss/postcss': {}
  }
}

/* app/globals.css */
@import "tailwindcss";

@theme {
  --color-primary: oklch(0.6 0.2 250);
}

// app/layout.tsx
import './globals.css'

export default function RootLayout({
  children
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body className="bg-white dark:bg-gray-900">{children}</body>
    </html>
  )
}

Server Components

Tailwind works seamlessly with React Server Components:

// app/page.tsx (Server Component)
export default function Home() {
  return (
    <main className="container mx-auto px-4 py-8">
      <h1 className="text-4xl font-bold text-gray-900 dark:text-white">
        Welcome
      </h1>
      <p className="mt-4 text-gray-600 dark:text-gray-300">
        Server-rendered with Tailwind
      </p>
    </main>
  )
}

Dark Mode with next-themes

npm install next-themes

// app/providers.tsx
'use client'

import { ThemeProvider } from 'next-themes'

export function Providers({ children }: { children: React.ReactNode }) {
  return (
    <ThemeProvider attribute="class" defaultTheme="system" enableSystem>
      {children}
    </ThemeProvider>
  )
}

// app/layout.tsx
import { Providers } from './providers'
import './globals.css'

export default function RootLayout({
  children
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en" suppressHydrationWarning>
      <body>
        <Providers>{children}</Providers>
      </body>
    </html>
  )
}

/* globals.css - Add dark mode variant */
@import "tailwindcss";
@custom-variant dark (&:where(.dark, .dark *));

Vue 3

Setup with Vite

npm create vue@latest my-app
cd my-app

npm install -D tailwindcss @tailwindcss/vite

})

/* src/assets/main.css */
@import "tailwindcss";

// src/main.ts
import { createApp } from 'vue'
import App from './App.vue'
import './assets/main.css'

createApp(App).mount('#app')

Component Example

<!-- src/components/Button.vue -->
<script setup lang="ts">
defineProps<{
  variant?: 'primary' | 'secondary'
}>()
</script>

  <button
    class="px-4 py-2 rounded-lg font-medium transition-colors"
    :class="{
      'bg-blue-600 text-white hover:bg-blue-700': variant === 'primary',
      'bg-gray-200 text-gray-900 hover:bg-gray-300': variant === 'secondary'
    }"
  >
    <slot />
  </button>
</template>

</template>

<style scoped>
/* Reference global Tailwind definitions */

}
</style>

Alternative: CSS Variables

<template>
  <h1>Hello world!</h1>
</template>

<style scoped>
h1 {
  /* Use CSS variables directly - better performance */
  font-size: var(--text-2xl);
  font-weight: var(--font-bold);

Best Practices for All Frameworks

1. Use the Prettier Plugin

npm install -D prettier prettier-plugin-tailwindcss

// .prettierrc
{
  "plugins": ["prettier-plugin-tailwindcss"]
}

2. Install VS Code Extension

code --install-extension bradlc.vscode-tailwindcss

3. Create Reusable Components

Don't repeat long class strings—extract components:

// Instead of repeating this everywhere:
<button className="px-4 py-2 bg-blue-600 text-white rounded-lg hover:bg-blue-700 transition-colors">

// Create a component:
<Button variant="primary">Click me</Button>

4. Use clsx or tailwind-merge for Conditional Classes

npm install clsx tailwind-merge

import { clsx } from 'clsx'
import { twMerge } from 'tailwind-merge'

function cn(...inputs: ClassValue[]) {
  return twMerge(clsx(inputs))
}

// Usage
<div className={cn(
  "base-class",
  isActive && "active-class",
  disabled && "opacity-50"
)} />

5. Configure Path Aliases

// tsconfig.json
{
  "compilerOptions": {
    "paths": {
      "@/*": ["./src/*"],
      "@/components/*": ["./src/components/*"]
    }
  }
}

import { Button } from '@/components/Button'
