Quick Reference

How to Use Redirects

Test a redirect:

curl -i http://localhost:3000/privacy-policy
# Expected: 308 redirect to /privacy

Add a new redirect:

// In src/lib/redirectManagement.ts
export const MY_REDIRECTS: RedirectRule[] = [
  {
    from: '/old-url',
    to: '/new-url',
    status: 308,
    preserveQuery: true,
    isLegacy: true,
  },
];

// Add to ALL_REDIRECTS:
export const ALL_REDIRECTS: RedirectRule[] = [...PRIVACY_POLICY_REDIRECTS, ...MY_REDIRECTS];

Run tests:

# Unit tests
pnpm test src/lib/__tests__/redirectManagement.test.ts

# Integration tests
pnpm test src/middleware/__tests__/redirectManagement.test.ts

# Component tests
pnpm test src/app/privacy/__tests__/privacy-page.test.tsx

# All tests
pnpm test

View Privacy Policy:
