## 📖 Frameworks Supported

### Express.js
```javascript
const express = require('express');
const { createSecKavMiddleware } = require('@seckav/security-sdk');

const app = express();
app.use(createSecKavMiddleware({
  apiKey: 'your_api_key',
  organizationId: 'your_org_id'
}));
```

### Next.js
```javascript
// middleware.js
import { createSecKavNextMiddleware } from '@seckav/security-sdk';

export default createSecKavNextMiddleware({
  apiKey: 'your_api_key',
  organizationId: 'your_org_id'
});

export const config = {
  matcher: '/api/:path*'
};
```

### TypeScript
```typescript
import { createSecKavMiddleware, SecKavConfig } from '@seckav/security-sdk';

const config: SecKavConfig = {
  apiKey: 'your_api_key',
  organizationId: 'your_org_id',
  features: {
    rateLimit: true,
    security: true,
    analytics: true
  }
};

app.use(createSecKavMiddleware(config));
```

## ⚙️ Configuration Options

```javascript
const config = {
  // Required
  apiKey: 'your_api_key',
  organizationId: 'your_org_id',
  
  // Optional
  apiUrl: 'https://api.seckav.com',  // Custom API endpoint
  timeout: 5000,                     // Request timeout (ms)
  debug: false,                      // Enable debug logging
  
  // Features
  features: {
    rateLimit: true,                 // Enable rate limiting
    security: true,                  // Enable threat detection
    analytics: true,                 // Enable usage analytics
    encryption: false,               // Enable E2E encryption
    misconfigurationScanning: false  // Enable config scanning
  },
  
  // Error handling
  onError: (error) => {
    console.log('Security error:', error);
  }
};
```

## 🔧 Advanced Usage

### Custom Rate Limiting
```javascript
const sdk = new SecKavSDK({
  apiKey: 'your_api_key',
  organizationId: 'your_org_id'
});

// Check rate limit manually
const result = await sdk.checkRateLimit('/api/endpoint', 'GET', 'client-id');
if (!result.allowed) {
  return res.status(429).json({ error: 'Rate limited' });
}
```

### Security Settings
```javascript
const securitySettings = await sdk.getSecuritySettings('your_jwt_token');
console.log('Current security configuration:', securitySettings);
```

### Analytics Data
```javascript
// Get SDK information
const info = sdk.getInfo();
console.log('Enabled features:', info.enabledFeatures);
console.log('SDK version:', info.version);
```

## 🚨 Error Handling

The SDK uses a **fail-open** architecture - if there's an error, your API continues to work:

```javascript
app.use(createSecKavMiddleware({
  apiKey: 'your_api_key',
  organizationId: 'your_org_id',
  onError: (error) => {
    // Log errors but don't break the application
    console.error('SecKav error:', error.message);
    
    // Optional: Send to your monitoring service
    monitoring.reportError(error);
  }
}));
```
