Core Implementation

Vercel Configuration

Advanced Features

Edge Caching Strategy

// Intelligent caching middleware
export class EdgeCacheManager {
  async getResponse(req: NextRequest): Promise<NextResponse | null> {
    const cacheKey = this.generateCacheKey(req);
    const cached = await caches.default.match(cacheKey);

    if (cached) {
      return cached;
    }

    return null;
  }

  async setResponse(req: NextRequest, response: NextResponse, ttl: number = 3600): Promise<void> {
    const cacheKey = this.generateCacheKey(req);
    response.headers.set('Cache-Control', `s-maxage=${ttl}, stale-while-revalidate=${ttl * 2}`);

    const cacheResponse = new Response(response.body, {
      status: response.status,
      statusText: response.statusText,
      headers: response.headers
    });

    await caches.default.put(cacheKey, cacheResponse);
  }

  private generateCacheKey(req: NextRequest): string {
    const url = new URL(req.url);
    return `${req.method}:${url.pathname}:${url.search}`;
  }
}

Global Load Balancing

// Geographic routing optimization
export function getOptimalRegion(req: NextRequest): string {
  const country = req.headers.get('x-vercel-ip-country');
  const regionMap: Record<string, string> = {
    'US': 'iad1',  // East Coast US
    'CA': 'hnd1',  // West Coast US
    'GB': 'lhr1',  // United Kingdom
    'DE': 'fra1',  // Germany
    'FR': 'cdg1',  // France
  };

  return regionMap[country || 'US'] || 'iad1';
}

Performance Optimization

Bundle Size Reduction

// Dynamic imports for code splitting
const AdminPanel = dynamic(() => import('./components/AdminPanel'), {
  loading: () => <div>Loading admin panel...</div>
});

const AnalyticsChart = dynamic(() => import('./components/AnalyticsChart'), {
  ssr: false  // Client-side only
});

Image Optimization

// Optimized image component
import Image from 'next/image';

export function OptimizedImage({ src, alt, width, height }: ImageProps) {
  return (
    <Image
      src={src}
      alt={alt}
      width={width}
      height={height}
      placeholder="blur"
      blurDataURL="data:image/jpeg;base64,..."
      priority={width > 800}
    />
  );
}

Monitoring & Analytics

Real-time Performance

// Performance tracking setup
export function setupPerformanceTracking() {
  const monitoring = new VercelMonitoring();

  // Track Web Vitals
  if (typeof window !== 'undefined') {
    import('web-vitals').then(({ getCLS, getFID, getFCP, getLCP, getTTFB }) => {
      getCLS((metric) => monitoring.recordVital('CLS', metric.value));
      getFID((metric) => monitoring.recordVital('FID', metric.value));
      getFCP((metric) => monitoring.recordVital('FCP', metric.value));
      getLCP((metric) => monitoring.recordVital('LCP', metric.value));
      getTTFB((metric) => monitoring.recordVital('TTFB', metric.value));
    });
  }
}

Best Practices

Security

• Implement rate limiting on all edge functions
• Use security headers (CSP, HSTS, X-Frame-Options)
• Validate all input data
• Use environment variables for secrets

Performance

• Leverage edge caching aggressively
• Optimize bundle size with dynamic imports
• Use Next.js Image component for automatic optimization
• Monitor Core Web Vitals

Deployment

• Use preview deployments for testing
• Implement rollback strategies
• Monitor error rates and performance
• Use feature flags for safe rollouts
