## Why RizzUI?

RizzUI is designed for developers who want **beautiful, accessible components** without the bloat. Built with React 19 and Tailwind CSS v4, it provides everything you need to ship faster:

- 🎨 **Modern Design** - Clean, minimal components that look great out of the box
- ⚡️ **Lightweight** - Tree-shakeable exports, import only what you need
- 🎯 **Type-Safe** - Full TypeScript support with excellent autocomplete
- ♿️ **Accessible** - Built with accessibility in mind, following WCAG guidelines
- 🎭 **Customizable** - Easy theming with CSS variables, no config files needed
- 🌙 **Dark Mode** - Built-in dark mode support that just works
- 📦 **Zero Config** - Works with Tailwind CSS v4's CSS-first approach
- 🚀 **React 19 Ready** - Built for the latest React features

<br />

## Quick Start

### Requirements

- **React**: 19.1.0 or higher
- **Node.js**: 18.0.0 or higher
- **Package Manager**: pnpm 9.0.0+ (recommended), npm, yarn, or bun

### Installation

Install RizzUI and its peer dependencies:

```bash
# Using pnpm (recommended)
pnpm add rizzui @headlessui/react @floating-ui/react

# Using npm
npm install rizzui @headlessui/react @floating-ui/react

# Using yarn
yarn add rizzui @headlessui/react @floating-ui/react

# Using bun
bun add rizzui @headlessui/react @floating-ui/react
```

### Install Tailwind CSS

Before configuring RizzUI, you need to install Tailwind CSS v4. Follow the [official Tailwind CSS installation guide](https://tailwindcss.com/docs/installation/using-vite) for your build tool.

### Configure Tailwind CSS v4

RizzUI 2.0 uses **Tailwind CSS v4** with CSS-first configuration. No `tailwind.config.js` needed! 🎉

Create or update your `app/globals.css` (or `src/app/globals.css` for Next.js):

```css
@import 'tailwindcss';
@source '../../node_modules/rizzui/dist';
@plugin '@tailwindcss/forms';

/* ⚠️ Required: Dark mode variant */
@custom-variant dark (&:where([data-theme=dark], [data-theme=dark] *));

### PostCSS Configuration

Update your `postcss.config.mjs`:

```js
const config = {
  plugins: {
    '@tailwindcss/postcss': {},
  },
};
export default config;
```

## Usage

That's it! You're ready to use RizzUI components. Import them individually for optimal tree-shaking:

```jsx
import { Button } from 'rizzui/button';
import { Input } from 'rizzui/input';

export default function App() {
  return (
    <div>
      <Button>Click me</Button>
      <Input placeholder="Enter your name" />
    </div>
  );
}
```

**💡 Tip**: Import from specific paths (e.g., `rizzui/button`) instead of the main entry point for better tree-shaking and smaller bundle sizes.

<br />

## Theme Support

### Theme Provider Setup

RizzUI works seamlessly with `next-themes` for theme switching:

```jsx
'use client';

import { ThemeProvider as NextThemeProvider } from 'next-themes';

export function ThemeProvider({ children }: React.PropsWithChildren<{}>) {
  return (
    <NextThemeProvider
      enableSystem
      defaultTheme="system"
      disableTransitionOnChange
    >
      {children}
    </NextThemeProvider>
  );
}
```

### Theme Switcher Component

Here's a ready-to-use theme switcher:

```jsx
'use client';

import React from 'react';
import { useTheme } from 'next-themes';
import { ActionIcon } from 'rizzui/action-icon';
import { Dropdown } from 'rizzui/dropdown';
import { MoonIcon, SunIcon } from '@heroicons/react/24/outline';

export function ThemeSwitcher() {
  const { setTheme } = useTheme();

  return (
    <Dropdown>
      <Dropdown.Trigger>
        <ActionIcon variant="outline">
          <SunIcon className="size-5 dark:hidden" />
          <MoonIcon className="absolute hidden size-5 dark:block" />
          <span className="sr-only">Toggle theme</span>
        </ActionIcon>
      </Dropdown.Trigger>
      <Dropdown.Menu>
        <Dropdown.Item onClick={() => setTheme('light')}>Light</Dropdown.Item>
        <Dropdown.Item onClick={() => setTheme('dark')}>Dark</Dropdown.Item>
        <Dropdown.Item onClick={() => setTheme('system')}>System</Dropdown.Item>
      </Dropdown.Menu>
    </Dropdown>
  );
}
```
