Advanced Middleware Architecture

Middleware Chain System

The application uses a sophisticated middleware system for request processing:

Middleware chain configuration

export const config = {
  matcher: [
    '/api/next/search-suggest',
    '/((?!_next|bundle|Areas|_vercel|nextassets|favicon\\.ico|\\.well-known|robots\\.txt|sitemap\\.xml|sitemap-index\\.xml|149e|api)(?!.*\\.(?:js|css|css\\.map|mp3)$).*)',
  ],
};

Security Middleware

Middleware	Purpose	Implementation
setCSP	Content Security Policy enforcement	Prevents XSS and code injection
setNonce	Cryptographic nonce generation	Secure inline script execution
withCheckBotId	Bot detection and management	Protects against automated abuse
setGeoLocationHeaders	Geographic targeting	Location-based content delivery
checkRedirects	URL redirect management	SEO and URL structure optimization
withFlags	Feature flag evaluation	A/B testing and feature rollouts

Geographic and Personalization

Geographic targeting implementation

import { setGeoLocationHeaders } from './middlewares/setGeoLocationHeaders';
import { getOrGenerateVisitorId } from './middlewares/get-or-generate-visitor-id';

// Middleware for geographic targeting and visitor tracking

Feature Flag System

    status: 200,
  });
}

Cache Revalidation

Draft Content Preview

• Preview Mode: Draft content preview for content creators
• Authentication: Secure preview access control
• Real-time Updates: Live preview of content changes

Security Architecture

// Dynamic CSP with nonce-based script execution

Analytics and Monitoring

Vercel Analytics Integration

Analytics configuration

import { Analytics } from '@vercel/analytics/react';
import { SpeedInsights } from '@vercel/speed-insights/next';

// Integrated performance and usage analytics

Monitoring capabilities:

• Core Web Vitals: Performance metric tracking

  "functionFailoverRegions": ["sfo1", "cle1"],
  "git": {
    "deploymentEnabled": false
  }
}

Features:

4. Bundle Optimization: Code splitting and tree shaking
5. Asset Processing: Image and font optimization
6. Static Generation: Pre-rendered pages and assets
7. Deployment: Multi-region serverless deployment

Error Handling and Resilience

Error Boundaries

Global error handling

// src/app/error.tsx
export default function Error({
  error,
  reset,
}: {
  error: Error & { digest?: string }
  reset: () => void
}) {
  return (
    <div>
      <h2>Something went wrong!</h2>
      <button onClick={() => reset()}>Try again</button>
    </div>
  );
}

404 Handling

Custom 404 page

// src/app/not-found.tsx
export default function NotFound() {
  return (
    <div>
      <h2>Page Not Found</h2>
      <p>Could not find the requested resource.</p>
    </div>
  );
}

Common Use Cases

Content Publishing Workflow

Content management integration

// Publishing new content
const publishContent = async (contentId: string) => {
  // Validate content
  await validateContent(contentId);
  
  // Publish to CMS
  await publishToCMS(contentId);
  
  // Invalidate cache
  await revalidateContent(contentId);
  
  // Update sitemap
  await regenerateSitemap();
};

Lead Generation

Lead capture implementation

import { submitLeadForm } from '@schwab/server-actions/LeadActions';

// Server action for lead form submission
const handleLeadSubmission = async (formData: FormData) => {
  const result = await submitLeadForm(formData);
  return result;
};

Testing Strategy

Component Testing

Component testing pattern

import { render, screen } from '@testing-library/react';
import { expect, test } from '@jest/globals';

test('renders navigation component', () => {
  render(<Navigation />);
  expect(screen.getByRole('navigation')).toBeInTheDocument();
});

Integration Testing

• API Route Testing: Server-side endpoint validation
• Middleware Testing: Request/response pipeline validation
• Database Integration: Data layer testing
• External Service Mocking: Third-party API simulation

Troubleshooting

Common Issues

Issue	Cause	Solution
Port 3000 in use	Previous process running	Use kill script in dev command
CSP violations	Unsafe inline scripts	Add nonce to script tags
Feature flag errors	LaunchDarkly configuration	Verify flag key and targeting rules
Image loading fails	Invalid remote patterns	Check Next.js image configuration
Build failures	TypeScript errors	Run pnpm type-check
Test failures	Component dependencies	Verify mock configurations

Performance Issues

Core Web Vitals

Use Vercel Analytics dashboard to monitor real user performance metrics and identify optimization opportunities.

Security

Never disable CSP or bot protection in production. These security measures are critical for protecting user data and preventing abuse.
