## 🛠️ Installation & Setup

### NPM

## 🌐 API Support

Works with any Bitcoin Ordinals API:
- **Recursive endpoints** (recommended) - No Bitcoin node required
- **Standard endpoints** - Fallback support
- **Custom servers** - Configure your own endpoints

## 🚀 Service Worker Caching

The library includes an optional service worker for intelligent caching and offline support. The service worker provides:

- **Smart Caching** - Automatic caching of inscription content and metadata
- **Offline Support** - View previously loaded inscriptions without internet
- **Performance** - Dramatically faster load times for cached content
- **Bandwidth Savings** - Reduce API calls and data usage

### In-Memory Caching

The library includes built-in in-memory caching for improved performance:

```jsx
import { useInscriptionCache } from 'bitcoin-inscription-viewer';

function App() {
  const { 
    cachedData,
    cacheSize,
    clearCache,
    getCachedData,
    setCachedData
  } = useInscriptionCache();

  return (
    <div>
      <div>Cache Size: {Object.keys(cachedData).length} entries</div>
      <button onClick={clearCache}>Clear Cache</button>
      {/* Your inscription components */}
    </div>
  );
}
```

### Caching Features

- **Automatic Caching** - Content is automatically cached after first load
- **LRU Eviction** - Least recently used items are removed when cache is full
- **Memory Efficient** - Configurable cache size limits
- **Manual Control** - Programmatic cache management
- **Performance Monitoring** - Cache hit/miss statistics

The caching system improves load times for frequently viewed inscriptions and reduces API requests.
