[rajputomsingh]

Overview

Refactors the Marketplace module into a service-oriented architecture by extracting business logic from API routes, centralizing Prisma queries, introducing shared validation and response utilities, and adding a reusable caching layer.

Highlights

• Introduced lib/marketplace service layer
• Centralized Prisma queries with optimized selects
• Removed duplicated bidding logic
• Added shared DTO transformers and validation schemas
• Standardized API responses and logging
• Implemented Redis-backed caching with fallback support
• Simplified Marketplace hooks and UI components
• Consolidated Marketplace types into a single module
• Removed legacy marketplace utilities and duplicate code

Impact

• ~3,000+ lines of legacy code removed
• Thin API routes focused on request/response handling
• Better maintainability and separation of concerns
• Reduced database overfetching
• Improved cache utilization and API response times

Validation

• ✅ ESLint
• ✅ TypeScript
• ✅ Production Build
• ✅ Vercel Deployment

With the Marketplace architecture now modularized, upcoming work can focus on new features instead of infrastructure. This refactor provides a cleaner, more scalable foundation for the Catalyst release.
