-## Monitoring and Logging
-
-### Sentry Integration
-
-```typescript
-// sentry.client.config.ts
-import * as Sentry from '@sentry/nextjs';

-});
-
-// sentry.server.config.ts
-import * as Sentry from '@sentry/nextjs';

- tracesSampleRate: 0.1,
- environment: process.env.NODE_ENV,
-});
-```
-
-### Health Check Endpoint
-
-```typescript
-// app/api/health/route.ts
-import { NextResponse } from 'next/server';
-
-export async function GET() {
- try {
- // Check database connection
- await prisma.$queryRaw`SELECT 1`;
-
- return NextResponse.json({
- status: 'healthy',
- timestamp: new Date().toISOString(),
- uptime: process.uptime(),
- });
- } catch (error) {

- { status: 503 }
- );
- }

-## Performance Optimization Checklist
-
-- [ ] Enable output: 'standalone' for smaller Docker images
-- [ ] Configure CDN for static assets
-- [ ] Implement proper caching headers
-- [ ] Enable gzip/brotli compression
-- [ ] Optimize images with next/image
-- [ ] Minimize environment variables in client bundle
-- [ ] Set up monitoring and error tracking
-- [ ] Configure rate limiting
-- [ ] Implement health checks
-- [ ] Set up proper logging
-
-Always test deployments in staging environment before production and implement proper rollback strategies.
