# Code Duplication Analysis ## Photo Management Components ### Current Duplication - `PhotoGalleryComponent`, `PhotoManagerComponent`, and `FeaturedPhotoSelectorComponent` share similar: - Park model mounting logic - Photo collection handling - Basic photo management operations ### Recommendation 1. Create a base photo component trait/abstract class 2. Extract common photo loading and management logic 3. Implement specific features in child components ## Statistics Services ### Current Duplication - `StatisticsRollupService` and `StatisticsCacheService` have parallel implementations: - Similar entity iteration (areas, parks, operators) - Matching method patterns for each entity type - Redundant update/cache cycles ### Recommendation 1. Create a unified statistics processor 2. Implement the Strategy pattern for different statistics operations 3. Use a single iteration cycle for both updating and caching ## Location Components ### Current Duplication - `LocationMapComponent` and `LocationSelectorComponent` duplicate: - Location validation logic - State management for coordinates - Selection handling ### Recommendation 1. Extract common location logic to a trait 2. Create a shared location validation service 3. Implement a central location state manager ## Action Items 1. Immediate - Create base traits/abstracts for common functionality - Extract duplicate validation logic to services - Document common patterns for reuse 2. Long-term - Implement unified statistics processing - Create shared state management for locations - Establish component inheritance hierarchy ## Benefits 1. Maintainability - Single source of truth for common logic - Easier updates and bug fixes - Consistent behavior across components 2. Performance - Reduced memory usage - Optimized service calls - Better caching opportunities 3. Development - Clearer code organization - Reduced testing surface - Easier feature additions
