Module System Integration Summary

Date: December 26, 2025
Status: ✅ Complete

Overview

All module-related features have been wired to check module status before displaying. When a module is disabled, its features are completely hidden from both admin and customer interfaces.

4. Subscription Module (subscription)

Status: Not yet implemented (module registered, no features built)

---

5. Licensing Module (licensing)

Status: Not yet implemented (module registered, no features built)

Implementation Pattern

Frontend Check (React)

import { useModules } from '@/hooks/useModules';

export default function MyComponent() {
  const { isEnabled } = useModules();
  
  if (!isEnabled('my_module')) {
    return <DisabledStateUI />;
  }
  
  // Normal component render
}

Backend Check (PHP)

use WooNooW\Core\ModuleRegistry;

public function my_endpoint($request) {
    if (!ModuleRegistry::is_enabled('my_module')) {
        return new WP_Error('module_disabled', 'Module is disabled', ['status' => 403]);
    }
    
    // Process request
}

Navigation Check (PHP)

// In NavigationRegistry.php
if (ModuleRegistry::is_enabled('my_module')) {
    $children[] = ['label' => 'My Feature', 'path' => '/my-feature'];
}

---

Files Modified

Admin SPA (1 file)

1. admin-spa/src/routes/Marketing/Newsletter.tsx - Newsletter page module check

Customer SPA (4 files)

1. customer-spa/src/pages/Account/Wishlist.tsx - Wishlist page module check
2. customer-spa/src/pages/Product/index.tsx - Product page wishlist button
3. customer-spa/src/components/ProductCard.tsx - Product card wishlist hearts
4. customer-spa/src/pages/Account/components/AccountLayout.tsx - Account menu filtering

Backend (2 files)

1. includes/Frontend/WishlistController.php - API endpoint protection
2. includes/Compat/NavigationRegistry.php - Navigation filtering

---

Testing Checklist

Newsletter Module

• Toggle newsletter OFF in Settings > Modules
• Verify "Newsletter" menu item disappears from Marketing
• Try accessing /marketing/newsletter directly
• Expected: Shows disabled message with link to settings
• Toggle newsletter ON
• Verify menu item reappears

Wishlist Module

• Toggle wishlist OFF in Settings > Modules
• Visit shop page
• Expected: No heart icons on product cards
• Visit product page
• Expected: No wishlist button
• Visit My Account
• Expected: No "Wishlist" menu item
• Try accessing /my-account/wishlist directly
• Expected: Shows disabled message
• Try API call: GET /woonoow/v1/account/wishlist
• Expected: 403 error "Wishlist module is disabled"
• Toggle wishlist ON
• Verify all features reappear

---

Performance Impact

Caching

• Module status cached for 5 minutes via React Query
• Navigation tree rebuilt automatically when modules toggled
• Minimal overhead (~1 DB query per page load)

Bundle Size

• No impact - features still in bundle, just conditionally rendered
• Future: Could implement code splitting for disabled modules

---

Future Enhancements

Phase 2

1. Code Splitting: Lazy load module components when enabled
2. Module Dependencies: Prevent disabling if other modules depend on it
3. Bulk Operations: Enable/disable multiple modules at once
4. Module Analytics: Track which modules are most used

Phase 3

1. Third-party Modules: Allow installing external modules
2. Module Marketplace: Browse and install community modules
3. Module Updates: Version management for modules
4. Module Settings: Per-module configuration pages

---

Developer Notes

Adding Module Checks to New Features

1. Import the hook:

   import { useModules } from '@/hooks/useModules';
   

2. Check module status:

   const { isEnabled } = useModules();
   if (!isEnabled('module_id')) return null;
   

3. Backend protection:

   if (!ModuleRegistry::is_enabled('module_id')) {
       return new WP_Error('module_disabled', 'Module disabled', ['status' => 403]);
   }
   

4. Navigation filtering:

   if (ModuleRegistry::is_enabled('module_id')) {
       $children[] = ['label' => 'Feature', 'path' => '/feature'];
   }
   

Common Pitfalls

1. Don't forget backend checks - Frontend checks can be bypassed
2. Check both module + settings - Some features have dual toggles
3. Update navigation version - Increment when adding/removing menu items
4. Clear cache on toggle - ModuleRegistry auto-clears navigation cache
