Product Details Report

Scope

Sprint 6 implemented the product details route and UI using the frozen architecture and the existing Product Domain. No authentication, payment, bootstrap, or backend API contracts were changed.

The route and UI consume ProductFacade only. The new product details module does not use DTOs, HttpClient, environment configuration, or storage.

Implemented Route

• /product/:id

Legacy /item/:id now redirects to /product/:id for compatibility.

Implemented Module

Product Details Container

• src/app/features/website/product/containers/product-details-container.component.ts
• src/app/features/website/product/containers/product-details-container.component.html

Responsibilities implemented:

• Reads the route id.
• Loads the product through ProductFacade only.
• Handles loading, error, and missing-product states.
• Computes and passes the Product Domain Model to reusable child components.
• Loads related products from the same category through ProductFacade.
• Supports variant selection and computed price/stock updates.

• Plain description fallback

Related Products

• src/app/features/website/product/components/related-products/related-products.component.ts
• src/app/features/website/product/components/related-products/related-products.component.html
• src/app/features/website/product/components/related-products/related-products.component.scss

Features:

• Uses existing ProductFacade results
• Excludes the current product
• Reuses the shared product card

Product Domain Usage

All product details UI code uses Product Domain models and ProductFacade. Backend DTOs remain isolated to the domain/provider layer.

The container derives all view state locally from the product model:

• selected color
• selected size
• effective price
• effective currency
• effective remaining stock
• gallery selection
• related products

Navigation Updates

Updated links to use the new route surface:

• product card navigation
• carousel item links
• cart item links
• category item links
• catalog module product navigation

Validation

Completed checks:

• Product loads through ProductFacade.
• Variant changes update displayed price.
• Stock changes correctly when variant selection changes.
• Gallery works with primary and thumbnail media.
• Related products work through the same-category product query.
• Components are reusable and input/output-only.
• No DTO usage in the new product details module.
• No HttpClient in the new product details UI.
• No storage or environment usage in the new product details UI.
• Build passes.

Build validation:

npm run build
