2. Performance Instrumentation: Add timing logs (if needed)

   • Queue load times
   • Action completion times
   • Time: ~30 minutes

Migration Guide

For New Admin Pages

import { useAdminGuard } from '@/hooks/useAdminGuard';
import { LoadingGate } from '@/components/common/LoadingGate';

export default function NewAdminPage() {
  const { isLoading, isAuthorized, needsMFA } = useAdminGuard();

  return (
    <AdminLayout>
      <LoadingGate
        isLoading={isLoading}
        isAuthorized={isAuthorized}
        needsMFA={needsMFA}
      >
        <YourPageContent />
      </LoadingGate>
    </AdminLayout>
  );
}

For Forms with Validation

import { emailSchema, validateEmail } from '@/lib/adminValidation';

// Simple validation
const result = validateEmail(input);
if (!result.valid) {
  toast({ title: 'Error', description: result.error });
}

// Form validation with react-hook-form
const form = useForm({
  resolver: zodResolver(emailSchema)
});

For Sorting Controls

import { SortControls } from '@/components/common/SortControls';

<SortControls
  sortConfig={sortConfig}
  onSortChange={handleSortChange}
  options={[
    { field: 'created_at', label: 'Date' },
    { field: 'username', label: 'User' },
  ]}
/>

Lessons Learned

What Worked Well

1. Phased Approach: Breaking work into 4 clear phases allowed focused effort
2. Comprehensive Documentation: Each phase documented for future reference
3. Type Safety First: Eliminating any types prevented many runtime errors
4. Reusable Components: Investment in components pays off quickly
5. Database Indexes: Massive performance improvement with minimal effort

What Could Be Improved

1. Earlier Testing: Unit tests would have caught some issues sooner
2. Performance Monitoring: Should have instrumentation from day 1
3. Component Planning: Some components could be split earlier
4. Migration Communication: Better coordination on breaking changes

Best Practices Established

1. Always use useAdminGuard: No more duplicate auth logic
2. Wrap localStorage: Always use try-catch for storage operations
3. Memoize callbacks: Prevent unnecessary re-renders
4. Type everything: Avoid any at all costs
5. Document decisions: Why is as important as what
