- Create service layer for email generation (PaymentMethodService, OrderTransformerService, EmailBuilderService)
- Extract all hardcoded values to configuration files
- Add proper TypeScript types for all email data structures
- Update GraphQL subscription to include transactions and events
- Refactor order-created, order-cancelled templates to use new architecture
- Payment method now dynamically detected from order transactions
This makes the email system:
- Testable: Each service can be unit tested independently
- Configurable: All values in config.ts, no hardcoding
- Extensible: Easy to add new languages or payment methods
- Maintainable: Clear separation of concerns
