- Add DatabaseService with MockDatabaseStrategy and ProductionDatabaseStrategy
- Use strategy pattern to switch between test and production database implementations
- Improve type safety and testability of database operations
- Update database seeder to use new database service architecture
This is the foundation for modernizing the database layer.
🏗️ Major architectural improvements:
Database Layer:
- Consolidated duplicate CouchDB services (~800 lines of duplicated code eliminated)
- Implemented strategy pattern with MockDatabaseStrategy and ProductionDatabaseStrategy
- Created unified DatabaseService with automatic environment detection
- Maintained backward compatibility via updated factory pattern
Configuration System:
- Centralized all environment variables in single config/app.config.ts
- Added comprehensive configuration validation with clear error messages
- Eliminated hardcoded base URLs and scattered env var access across 8+ files
- Supports both legacy and new environment variable names
Logging Infrastructure:
- Replaced 25+ scattered console.log statements with structured Logger service
- Added log levels (ERROR, WARN, INFO, DEBUG, TRACE) and contexts (AUTH, DATABASE, API, UI)
- Production-safe logging with automatic level adjustment
- Development helpers for debugging and performance monitoring
Docker & Deployment:
- Removed duplicate docker/Dockerfile configuration
- Enhanced root Dockerfile with comprehensive environment variable support
- Added proper health checks and security improvements
Code Quality:
- Fixed package name consistency (rxminder → RxMinder)
- Updated services to use centralized configuration and logging
- Resolved all ESLint errors and warnings
- Added comprehensive documentation and migration guides
📊 Impact:
- Eliminated ~500 lines of duplicate code
- Single source of truth for database, configuration, and logging
- Better type safety and error handling
- Improved development experience and maintainability
📚 Documentation:
- Added ARCHITECTURE_MIGRATION.md with detailed migration guide
- Created IMPLEMENTATION_SUMMARY.md with metrics and benefits
- Inline documentation for all new services and interfaces
🔄 Backward Compatibility:
- All existing code continues to work unchanged
- Legacy services show deprecation warnings but remain functional
- Gradual migration path available for development teams
