## Installation

```bash
npm install strata-storage
```

Or using yarn:

```bash
yarn add strata-storage
```

Or using pnpm:

```bash
pnpm add strata-storage
```

## Quick Start

### Basic Usage

```typescript
import { Strata } from 'strata-storage';

// Create and initialize storage
const storage = new Strata();
await storage.initialize();

// Store data
await storage.set('username', 'john_doe');
await storage.set('user', {
  id: 123,
  name: 'John Doe',
  email: 'john@example.com'
});

// Retrieve data
const username = await storage.get('username');
const user = await storage.get('user');

// Remove data
await storage.remove('username');

// Clear all data
await storage.clear();
```

### Advanced Features

#### Encryption

```typescript
const storage = new Strata({
  encryption: {
    enabled: true,
    password: 'your-secure-password'
  }
});

await storage.initialize();
await storage.set('sensitiveData', { token: 'secret' });
```

#### Time-To-Live (TTL)

```typescript
// Data expires in 1 hour
await storage.set('sessionData', data, {
  ttl: 60 * 60 * 1000
});
```

#### Compression

```typescript
const storage = new Strata({
  compression: {
    enabled: true,
    threshold: 1024 // Compress data larger than 1KB
  }
});

await storage.initialize();
await storage.set('largeData', bigObject);
```

#### Cross-Tab Sync

```typescript
const storage = new Strata({
  sync: { enabled: true }
});

await storage.initialize();

// Subscribe to changes from other tabs
storage.subscribe((change) => {
  console.log(`Key ${change.key} changed to:`, change.newValue);
});
```

## Platform Support

### Web Browsers
- **localStorage** - Simple key-value storage
- **sessionStorage** - Session-scoped storage
- **IndexedDB** - Large structured data
- **Cookies** - Cookie-based storage
- **Cache API** - HTTP cache storage
- **Memory** - In-memory storage

### iOS (via Capacitor)
- **UserDefaults** - User preferences
- **Keychain** - Secure credential storage
- **SQLite** - Database storage
- **FileManager** - File-based storage

### Android (via Capacitor)
- **SharedPreferences** - Simple key-value storage
- **EncryptedSharedPreferences** - Secure storage
- **SQLite** - Database storage
- **File Storage** - File-based storage

## Framework Integrations

### React

```typescript
import { useStrata } from 'strata-storage/react';

function MyComponent() {
  const { data, loading, set, remove } = useStrata('myKey');

  return (
    <div>
      <p>{data}</p>
      <button onClick={() => set('newValue')}>Update</button>
    </div>
  );
}
```

### Vue

```typescript
import { useStrata } from 'strata-storage/vue';

export default {
  setup() {
    const { data, loading, set, remove } = useStrata('myKey');

    return { data, loading, set, remove };
  }
};
```

### Angular

```typescript
import { StrataService } from 'strata-storage/angular';

@Component({ /* ... */ })
export class MyComponent {
  constructor(private storage: StrataService) {}

  async saveData() {
    await this.storage.set('key', 'value');
  }
}
```

| `cache` | Web | HTTP cache |
| `memory` | All | Temporary in-memory |
| `preferences` | Mobile | User preferences (UserDefaults/SharedPreferences) |
| `secure` | Mobile | Encrypted storage (Keychain/EncryptedSharedPreferences) |
| `sqlite` | Mobile | Database storage |
| `filesystem` | Mobile | File-based storage |

## Requirements

## Why Strata Storage?

### Zero Dependencies
Unlike other storage solutions that depend on multiple packages, Strata Storage has **zero runtime dependencies**. Everything is built from scratch, ensuring:
- Smaller bundle size
- No dependency conflicts
- Better security
- Full control over implementation

### Universal API
One API works everywhere. No need to learn different APIs for web and mobile, or switch between libraries:

```typescript
// Same code works on web, iOS, and Android
await storage.set('key', 'value');
const value = await storage.get('key');
```

### Built-in Features
Advanced features included out of the box:
- Encryption (Web Crypto API / Native Crypto)
- Compression (LZ-string algorithm)
- TTL/Expiration
- Cross-tab sync
- Advanced queries
- Data migrations
