🚀 Current Work

Phase: Phase 4 - Cart (Shopping Cart) COMPLETED (2025-11-03)

Deliverables Summary:

Completed comprehensive shopping cart implementation with both desktop and mobile-optimized UI:

API Endpoints (4):

  • GET /api/cart - Fetch user/guest cart with calculated totals
  • POST /api/cart/items - Add products to cart with validation
  • PATCH /api/cart/items/[id] - Update item quantities with stock checking
  • DELETE /api/cart/items/[id] - Remove items from cart

State Management:

  • useCart composable: Full CRUD operations for cart management
    • Functions: fetchCart(), addItem(), updateItem(), removeItem(), clearCart()
    • Computed properties: items, total, itemCount
    • Reactive state management with automatic API calls

UI Components (2):

  • CartItem.vue: Display product with quantity controls and remove option
  • CartSummary.vue: Show subtotal, VAT, total with "Zur Kasse" button

Pages:

  • pages/warenkorb.vue: Full cart display page with empty state handling

Key Features Implemented:

  • Session-based cart for guests (session_id storage)
  • Database-persistent cart for authenticated users (user_id storage)
  • 30-day cart persistence with automatic cleanup
  • Real-time total calculation (subtotal, 7% VAT, final total)
  • Product availability validation
  • Role-based visibility enforcement
  • Responsive design (desktop + mobile)

Design Implementation:

  • Desktop: Right-side sidebar (400px) with sticky header/footer
  • Mobile: Floating Action Button (FAB) with Bottom Sheet integration
  • Conditional FAB: Only renders on product pages when cart not empty
  • Badge display: Shows cart item count in real-time

Quality Assurance:

  • Full CRUD operation testing
  • Cart persistence validation across page reloads
  • Stock validation and error handling
  • Performance optimization (efficient queries, no N+1 issues)
  • Documentation of cart logic and data flow

Phase: Phase 3 - Authentication VALIDATED & COMPLETED (2025-11-01)

Validation Summary:

  • Login flow tested with Playwright - SUCCESS
  • User created in database with experimenta_id (Cidaas sub: 97dcde33-d12e-4275-a0d5-e01cfbea37c2)
  • Email, first name, last name correctly stored in users table
  • Session management functional
  • Timestamps (created_at, updated_at) working
  • Test credentials documented in .env.example
  • Documentation updated to reflect Password Grant Flow implementation

Implementation Note: Actual implementation uses Password Grant Flow (not Authorization Code Flow with PKCE). This was a deliberate choice for MVP simplicity. Authorization Code Flow can be added later for SSO/Social login support.

Tasks Completed (18/18):

  • Install nuxt-auth-utils + jose
  • Configure Cidaas environment variables in .env
  • Add Cidaas config to nuxt.config.ts runtimeConfig
  • Create Cidaas API client utility (server/utils/cidaas.ts) with loginWithPassword()
  • Create JWT validation utility (server/utils/jwt.ts)
  • Create /api/auth/login.post.ts endpoint (Password Grant)
  • Create /api/auth/register.post.ts endpoint
  • Create /api/auth/logout.post.ts endpoint
  • Create /api/auth/me.get.ts endpoint
  • Create useAuth composable (composables/useAuth.ts)
  • Create LoginForm component (components/Auth/LoginForm.vue)
  • Create RegisterForm component (components/Auth/RegisterForm.vue)
  • Create auth page with tabs (pages/auth.vue)
  • Create auth middleware (middleware/auth.ts)
  • Create rate-limit middleware (server/middleware/rate-limit.ts)
  • Test authentication flow end-to-end (VALIDATED 2025-11-01)
  • Validate database user creation (VALIDATED 2025-11-01)
  • Update documentation to reflect actual implementation

Next Steps:

  1. PRIORITY: Begin Phase 5 - Checkout (Forms & Flow):

    • Read tasks/05-checkout.md
    • Create checkout schema (Zod) with billing address validation
    • Build CheckoutForm and AddressForm components
    • Implement address pre-fill from user profile
    • Add form validation with VeeValidate
    • Test complete checkout flow
  2. PRIORITY: Then Phase 6 - Products (Display & List):

    • Read tasks/06-products.md
    • Create product API endpoints (/api/products)
    • Build ProductCard and ProductList components
    • Implement product detail pages
    • Add product images handling
    • Test product display and filtering

🎉 Next Steps

  1. PRIORITY: Start Phase 5 - Checkout (Forms & Flow)

    • Read tasks/05-checkout.md for detailed tasks
    • Create checkout schema (Zod) with billing address validation
    • Build CheckoutForm and AddressForm components
    • Implement address pre-fill from user profile
    • Add form validation with VeeValidate
    • Create checkout page with multi-step form
    • Create /api/checkout/validate endpoint
    • Test complete checkout flow end-to-end
  2. PRIORITY: Then Phase 6 - Products (Display & List)

    • Read tasks/06-products.md for detailed tasks
    • Create /api/products/index.get.ts endpoint (list all products with role filtering)
    • Create /api/products/[id].get.ts endpoint (product details)
    • Build ProductCard component for product listings
    • Build ProductList component for product grid
    • Create ProductDetail page for individual product pages
    • Implement product image handling
    • Test product display with role-based visibility
    • Add product filtering and sorting

Rationale: The cart functionality is now complete. Next, we complete the checkout flow to finalize the purchase workflow, then implement product display to ensure users can see and select products. This sequence (cart → checkout → products) allows for incremental testing of the complete e-commerce flow.


Let's build this! 🚀
