## 🚀 Quick Start

### Installation

```bash
# Install core package
npm install @scrubbe-auth/analytics

# Or install all modules
npm install @scrubbe-auth/analytics @scrubbe-auth/device-fingerprint @scrubbe-auth/location-tracker @scrubbe-auth/network-info @scrubbe-auth/user-tracker



## Basic Usage
```import { Analytics } from '@scrubbe-auth/analytics';

 Initialize with minimal configuration
const analytics = new Analytics({
  projectId: 'your-project-id',
  apiKey: 'your-api-key'
});

 Start tracking
   await analytics.init();

Track events
  analytics.track('button_click', {
  buttonId: 'cta-signup',
  page: '/landing'
}); ```


## Advanced Setup
``` import { Analytics } from '@scrubbe-auth/analytics';
import { DeviceFingerprint } from '@scrubbe-auth/device-fingerprint';
import { LocationTracker } from '@scrubbe-auth/location-tracker';

const analytics = new Analytics({
  projectId: 'your-project-id',
  apiKey: 'your-api-key',
  autoTrack: true,
  privacy: {
    respectDNT: true,
    anonymizeIP: true
  }
});

// Add advanced tracking modules
const deviceFP = new DeviceFingerprint({
  enableCanvas: true,
  enableWebGL: true
});

const locationTracker = new LocationTracker({
  enableGPS: false, // Requires user permission
  enableIP: true
});

// Integrate modules
analytics.use(deviceFP);
analytics.use(locationTracker);

// Start comprehensive tracking
await analytics.start(); ```



## 📊 Usage Examples

### Event Tracking

```// Page views
analytics.page('/dashboard', {
  category: 'app',
  userId: 'user_123'
});

// Custom events
analytics.track('purchase_completed', {
  orderId: 'order_456',
  revenue: 99.99,
  currency: 'USD'
});

// User identification
analytics.identify('user_123', {
  email: 'user@example.com',
  plan: 'premium'
}); ```


### Device Fingerprinting

``` import { DeviceFingerprint } from '@scrubbe-auth/device-fingerprint';

const deviceFP = new DeviceFingerprint({
  enableCanvas: true,
  enableWebGL: true,
  enableAudio: false // Disable for better performance
});

const fingerprint = await deviceFP.generate();
console.log('Unique Device ID:', fingerprint.deviceId);
console.log('Confidence Score:', fingerprint.confidence); ```


### Location Tracking 
``` import { LocationTracker } from '@scrubbe-auth/location-tracker';

const locationTracker = new LocationTracker({
  enableGPS: true,
  accuracy: 'high'
});

const location = await locationTracker.getLocation();
console.log('Location:', location.city, location.country);  ```



## ⚙️ Configuration

### Environment Variables

# Required
scrubbe-auth_PROJECT_ID=your-project-id
scrubbe-auth_API_KEY=your-api-key

# Optional
scrubbe-auth_ENVIRONMENT=production
scrubbe-auth_DEBUG=false
scrubbe-auth_BATCH_SIZE=100



### Privacy Settings

``` const analytics = new Analytics({
  projectId: 'your-project-id',
  apiKey: 'your-api-key',
  privacy: {
    respectDNT: true,        // Honor Do Not Track
    anonymizeIP: true,       // Anonymize IP addresses
    consentRequired: true,   // Require explicit consent
    cookieConsent: true      // Cookie consent integration
  }
});   ```


### Performance Optimization

``` const analytics = new Analytics({
  projectId: 'your-project-id',
  apiKey: 'your-api-key',
  batchSize: 100,           // Events per batch
  flushInterval: 5000,      // Flush every 5 seconds
  transport: {
    compression: true,      // Enable data compression
    retries: 3             // Retry failed requests
  }
});  ```
