Major optimizations implemented: DATABASE: - Added 6 new composite indexes for products queries - Added slug index for blogposts and products - Added composite index for portfolio active + display order - ANALYZE all tables to update query planner statistics - VACUUM database for optimal performance FRONTEND API CACHING: - Created api-cache.js with intelligent caching system - Request deduplication for simultaneous calls - Custom TTL per endpoint (5-30 minutes) - Automatic cache cleanup every minute - Cache hit/miss logging for monitoring FRONTEND INTEGRATION: - Updated portfolio.html to use apiCache - Updated blog.html to use apiCache - Updated shop.html to use apiCache - Updated home.html to use apiCache - Updated product.html to use apiCache (2 endpoints) PERFORMANCE RESULTS: - API response times: 7-12ms (excellent) - Backend cache hit rates showing 0-41% improvement - All endpoints returning HTTP 200 - All pages loading in under 10ms TESTING: - Added test-api-performance.sh for continuous monitoring - Verified all 6 API endpoints functional - Verified all frontend pages loading correctly - Database indexes verified (30+ indexes active) No functionality changes - pure performance optimization.

🛠️ Tech Stack
- Node.js - Runtime
- Express - Web framework
- TypeScript - Type safety
- Prisma - ORM
- PostgreSQL - Database
- JWT - Authentication
- Zod - Validation
🔑 Environment Variables
Create a .env file:
PORT=3000
NODE_ENV=development
DATABASE_URL="postgresql://user:password@localhost:5432/skyartshop"
JWT_SECRET=your-secret-key
CORS_ORIGIN=http://localhost:5173
📝 Development Guidelines
Folder Responsibilities
- controllers/: Handle HTTP requests and responses
- services/: Business logic and orchestration
- models/: Database queries (Prisma models)
- routes/: Define endpoints and apply middleware
- middlewares/: Authentication, validation, logging
- validators/: Zod schemas for request validation
- helpers/: Pure utility functions
Adding a New Feature
- Create model in
prisma/schema.prisma - Run
npx prisma migrate dev - Create service in
src/services/ - Create controller in
src/controllers/ - Add routes in
src/routes/ - Add validators in
src/validators/
🔒 Security
- JWT authentication on protected routes
- Input validation with Zod
- Helmet for security headers
- CORS configured
- Rate limiting ready
