What problem does it solve?
When adding a new value to a domain union type (for example CalculationBase), the change can cause a build break because the same union value is hardcoded in the infrastructure layer (API request/response models). The domain type compiles, but the adapter that maps domain models to API requests may fail with a type mismatch.
Core Features & Use Cases
- Synchronize domain union values across domains/models and infrastructure/api to prevent drift.
- Provide a disciplined approach to propagate changes safely, reducing build failures and runtime errors.
- Use in a DDD-style project when evolving domain unions that must stay in sync with API models.
Quick Start
Update a domain union type and then search the codebase for all occurrences to ensure domain and infrastructure references are updated consistently.
