## 📦 Installation

### From NPM (Recommended)

```bash
# npm
npm install @flint-org/ui framer-motion tailwindcss

# pnpm
pnpm add @flint-org/ui framer-motion tailwindcss

# yarn
yarn add @flint-org/ui framer-motion tailwindcss
```

### From GitHub Packages

```bash
npm install @flint-org/ui --registry=https://npm.pkg.github.com
```

### Peer Dependencies

The library requires these peer dependencies:

- `react` >= 18.0.0
- `react-dom` >= 18.0.0
- `framer-motion` (optional, for animated components)
- `tailwindcss` >= 3.0.0 (for styling)

---

## 🚀 Quick Start

### 1. Install the package

```bash
pnpm add @flint-org/ui framer-motion tailwindcss
```

### 2. Import CSS

Add to your root layout or `_app.tsx`:

```typescript
import '@flint-org/ui/styles';
```

### 3. Configure Tailwind (Optional but recommended)

Use our preset for the full experience:

```javascript
// tailwind.config.js
import flintPreset from '@flint-org/ui/preset';

export default {
  presets: [flintPreset],
  content: [
    './app/**/*.{ts,tsx}',
    './components/**/*.{ts,tsx}',
    './node_modules/@flint-org/ui/dist/**/*.js',
  ],
};
```

### 4. Use components

```tsx
import { Button, Card, AnimatedCounter } from '@flint-org/ui';

export default function App() {
  return (
    <Card>
      <h2>Total Revenue</h2>
      <AnimatedCounter value={45231} prefix="$" />
      <Button>View Details</Button>
    </Card>
  );
}
```

## 📦 Import Strategies

@flint-org/ui supports multiple import patterns to optimize your bundle size. Choose based on your needs:

### ⚡ Optimized Imports (Recommended for Production)

Import only what you need for the smallest bundle sizes:

```tsx
// UI Primitives (~1-2KB each)
import { Button } from '@flint-org/ui/button';
import { Card } from '@flint-org/ui/card';
import { Input } from '@flint-org/ui/input';

// Custom Components
import { DataTable } from '@flint-org/ui/data-table';  // ~10KB (includes TanStack Table)
import { Navbar } from '@flint-org/ui/navbar';

// Animated Components
import { AnimatedCounter } from '@flint-org/ui/animated/animated-counter';  // ~15KB (includes Framer Motion)
import { TiltCard } from '@flint-org/ui/animated/tilt-card';

// Utilities & Hooks
import { cn } from '@flint-org/ui/utils';
import { useToast } from '@flint-org/ui/hooks';
```

### 🚀 Convenience Import (Quick Start/Prototyping)

Import from the main entry for faster development:

```tsx
// Full bundle (~76KB) - includes all components
import { Button, Card, Input, DataTable, AnimatedCounter } from '@flint-org/ui';
```

### 📊 Bundle Size Comparison

| Import Method | Bundle Size | Use Case |
|---------------|-------------|----------|
| `@flint-org/ui/button` | **~1.9KB** | ✅ Production (97% smaller!) |
| `@flint-org/ui/data-table` | **~10KB** | Complex data tables |
| `@flint-org/ui/animated/counter` | **~15KB** | Animated components |
| `@flint-org/ui` (barrel) | **~76KB** | Quick prototyping |

### 🎯 Best Practices

1. **Production apps**: Use individual imports (`@flint-org/ui/button`)
2. **Prototypes/demos**: Use barrel import (`@flint-org/ui`)
3. **Animated components**: Only import when you need animations
4. **Tree-shaking**: Works automatically with individual imports
5. **Next.js App Router**: Add `"use client"` to your page/component if needed

**Example: Optimized Next.js Page**

```tsx
'use client';

import { Button } from '@flint-org/ui/button';
import { Card, CardHeader, CardTitle, CardContent } from '@flint-org/ui/card';
import { cn } from '@flint-org/ui/utils';

export default function Dashboard() {
  return (
    <div className={cn('container mx-auto p-6')}>
      <Card>
        <CardHeader>
          <CardTitle>Dashboard</CardTitle>
        </CardHeader>
        <CardContent>
          <Button>Get Started</Button>
        </CardContent>
      </Card>
    </div>
  );
}
```

Bundle size: **~3-5KB** instead of 76KB! 🎉

## 🎨 Theming

### Dark Mode

The library includes built-in dark mode support via CSS variables:

```tsx
import { ThemeProvider } from 'next-themes';

function App({ children }) {
  return (
    <ThemeProvider attribute="class" defaultTheme="system" enableSystem>
      {children}
    </ThemeProvider>
  );
}
```

### Customization

Override CSS variables to match your brand:

```css
:root {
  --ui-primary: 262 83% 58%;
  --ui-background: 0 0% 100%;
  --ui-foreground: 222 47% 11%;
  --ui-radius: 0.5rem;
  /* ... more variables */
}

.dark {
  --ui-primary: 263 70% 50%;
  --ui-background: 224 71% 4%;
  --ui-foreground: 213 31% 91%;
  /* ... more variables */
}
```

---

## 💡 Usage Examples

import { Button } from '@flint-org/ui';

<Button variant="default" size="md">
  Click me
</Button>
```

### Data Table

```tsx
import { DataTable } from '@flint-org/ui';

const columns = [
  { accessorKey: 'name', header: 'Name' },
  { accessorKey: 'email', header: 'Email' },
];

<DataTable columns={columns} data={users} />
```

  return <Button {...props} />;
};
```

---

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

describe('Button', () => {
  it('should render with children', () => {
    render(<Button>Click me</Button>)
    expect(screen.getByRole('button')).toHaveTextContent('Click me')
