# Modularization Progress Report
|
||
|
|
|
||
|
|
## Completed Tasks ✅
|
||
|
|
|
||
|
|
### Phase 1: Foundation (COMPLETED)
|
||
|
|
|
||
|
|
1. ✅ **Core Interfaces Created**
|
||
|
|
- `/src/core/interfaces/repositories/` - All repository interfaces
|
||
|
|
- `/src/core/interfaces/services/` - All service interfaces
|
||
|
|
- Clean exports via index.ts files
|
||
|
|
|
||
|
|
2. ✅ **Repository Implementations**
|
||
|
|
- `PaymentRepository` - Full CRUD for payments
|
||
|
|
- `MessageRepository` - ISO message data access
|
||
|
|
- `OperatorRepository` - Operator management
|
||
|
|
- `SettlementRepository` - Settlement tracking
|
||
|
|
|
||
|
|
3. ✅ **Services Converted to Instance-Based with DI**
|
||
|
|
- `MessageService` - Now uses repositories, accepts dependencies via constructor
|
||
|
|
- `TransportService` - Now accepts IMessageService via constructor
|
||
|
|
- `LedgerService` - Now uses PaymentRepository, accepts adapter via constructor
|
||
|
|
- `ScreeningService` - New instance-based service (replaces ScreeningEngine)
|
||
|
|
|
||
|
|
4. ✅ **Simple DI Container**
|
||
|
|
- `ServiceContainer` class for service registration and resolution
|
||
|
|
- Factory pattern support
|
||
|
|
|
||
|
|
## In Progress 🔄
|
||
|
|
|
||
|
|
### Phase 2: Core Orchestration
|
||
|
|
|
||
|
|
- **PaymentWorkflow** - Needs to be refactored to accept all services via constructor
|
||
|
|
- **DI Container Setup** - Need to wire all services together
|
||
|
|
- **Route Updates** - Update route handlers to use DI container
|
||
|
|
|
||
|
|
## Remaining Tasks 📋
|
||
|
|
|
||
|
|
### Critical
|
||
|
|
1. **Refactor PaymentWorkflow**
|
||
|
|
- Accept all services via constructor (ILedgerService, IMessageService, ITransportService, IScreeningService)
|
||
|
|
- Replace direct database queries with repository calls
|
||
|
|
- Update all static method calls
|
||
|
|
|
||
|
|
2. **Update Route Handlers**
|
||
|
|
- Wire services via DI container
|
||
|
|
- Update PaymentWorkflow instantiation
|
||
|
|
- Update all static service calls
|
||
|
|
|
||
|
|
3. **Create Service Initialization**
|
||
|
|
- Setup function to initialize all repositories
|
||
|
|
- Setup function to initialize all services
|
||
|
|
- Wire dependencies correctly
|
||
|
|
|
||
|
|
### Important
|
||
|
|
4. **Add Index Files**
|
||
|
|
- Create index.ts files for all modules for clean exports
|
||
|
|
- Update imports to use path aliases consistently
|
||
|
|
|
||
|
|
5. **Testing**
|
||
|
|
- Update existing tests to use new structure
|
||
|
|
- Create mock repositories for testing
|
||
|
|
|
||
|
|
## Migration Notes
|
||
|
|
|
||
|
|
- Old static `ScreeningEngine` is preserved for backward compatibility
|
||
|
|
- New `ScreeningService` provides instance-based implementation
|
||
|
|
- All services now implement their respective interfaces
|
||
|
|
- Repository pattern separates data access from business logic
|
||
|
|
|
||
|
|
## Breaking Changes
|
||
|
|
|
||
|
|
⚠️ **Services are no longer static** - All service methods must be called on instances
|
||
|
|
⚠️ **Constructor injection required** - Services must be instantiated with dependencies
|
||
|
|
⚠️ **Repository pattern** - Database queries are now in repositories, not services
|
||
|
|
|
||
|
|
## Next Steps
|
||
|
|
|
||
|
|
1. Complete PaymentWorkflow refactoring
|
||
|
|
2. Create service initialization/bootstrap file
|
||
|
|
3. Update app.ts to use DI container
|
||
|
|
4. Update all route files
|
||
|
|
5. Test thoroughly
|
||
|
|
6. Update documentation
