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
