# Getting Started with TikTok Video Player

## 🚀 Quick Start

The TikTok Video Player is now ready to use! Here's how to get started:

### 1. **Test the Playground**
```bash
npm run playground
```
Open [http://localhost:3000](http://localhost:3000) to see the player in action.

### 2. **Features You'll See**
- ✅ **Infinite Scroll** - Scroll up/down to navigate videos
- ✅ **Auto-play** - Videos play automatically when in view
- ✅ **Keyboard Controls** - Space (play/pause), Arrow keys (navigate)
- ✅ **Action Bar** - Like, comment, share buttons with realistic counters
- ✅ **TikTok UI** - Exact replica of TikTok's design and interactions

### 3. **Integration with Mux**

Replace the mock video URLs with your Mux playback IDs:

```tsx
// In playground/src/App.tsx, replace MOCK_VIDEOS with:
const MOCK_VIDEOS = [
  {
    id: 'video_1',
    src: 'https://stream.mux.com/YOUR_PLAYBACK_ID.m3u8', // Your Mux URL
    poster: 'https://image.mux.com/YOUR_PLAYBACK_ID/thumbnail.jpg',
    author: '@your_creator',
    description: 'Your video description #hashtag',
    likes: 12500,
    comments: 234,
    shares: 89
  }
  // ... more videos
];
```

### 4. **Backend Integration**

The player is designed to work with your existing backend:

```tsx
// Load more videos from your API
const handleLoadMore = async () => {
  const response = await fetch('/api/videos?offset=' + videos.length);
  const newVideos = await response.json();
  setVideos(prev => [...prev, ...newVideos]);
};

// Handle user interactions
const handleLike = async (videoId: string) => {
  await fetch(`/api/videos/${videoId}/like`, { method: 'POST' });
  // Update UI optimistically
};
```

### 5. **Customization**

The player uses Tailwind CSS and can be fully customized:

```tsx
// Custom colors in tailwind.config.js
colors: {
  'your-brand-red': '#FF0000',
  'your-brand-blue': '#0000FF',
}

// Custom animations
animation: {
  'your-custom-spin': 'spin 2s linear infinite',
}
```
