PDP: backend-integrated product details, reviews, recommendations

Summary

This PR replaces the mock data in the Product Details Page (PDP) with real backend integration using Drizzle ORM. Key changes include:

  • New Server Actions: Added getProductReviews() and getRecommendedProducts() with complex SQL queries
  • Real Data Integration: Updated PDP to fetch actual product data including variants, images, and metadata
  • Suspense Loading: Wrapped reviews and recommendations in Suspense boundaries for non-blocking rendering
  • Not Found Handling: Added graceful error state for missing/invalid products
  • Type Safety: Introduced explicit TypeScript interfaces for Review and RecommendedProduct

The recommendation algorithm prioritizes products by category similarity first, then brand, then gender, using a weighted scoring system.

Review & Testing Checklist for Human

⚠️ IMPORTANT: This PR could not be fully tested locally due to missing DATABASE_URL configuration.

  • End-to-end PDP testing: Navigate to /products/[valid-id] and verify product details, pricing, variants, and images display correctly
  • Recommendation quality: Check that "You Might Also Like" shows relevant products (same category/brand/gender priority)
  • Reviews functionality: Verify reviews section loads and displays user ratings/comments with proper formatting
  • Edge case handling: Test with invalid product ID to confirm Not Found state renders properly
  • Performance monitoring: Check database query performance for the new complex joins and window functions
  • Loading states: Verify Suspense fallbacks appear correctly while reviews/recommendations load
  • Mobile responsiveness: Test PDP layout on different screen sizes

Recommended Test Plan:

  1. Set up DATABASE_URL in environment
  2. Run npm run db:push to sync schema
  3. Navigate to /products and click into several different product cards
  4. Test with both existing and non-existent product IDs
  5. Monitor network tab for query performance

Notes

  • Session Info: Requested by Adrian | JS Mastery (@adrianhajdin)
  • Session Link: https://app.devin.ai/sessions/37afa59494a841d785786fa174383da7
  • Database Schema: Uses existing schema without modifications (products, variants, images, reviews, users)
  • Query Optimization: New queries use window functions and joins that should be monitored for performance
  • Fallback Behavior: Empty reviews/recommendations return empty arrays rather than dummy data

Summary by CodeRabbit

Poem

A rabbit taps its paw with glee,
Links now hop to “/products/:id”, whee!
Reviews burrow in via Suspense,
Recommendations fence-to-fence.
Prices shimmer, galleries gleam—
Data-fed carrots fuel the theme.
Thump-thump: shipped like a dream. 🥕✨
