domain-modeling

Define domain model discriminated unions using Schema.TaggedStruct to generate automatic _tag fields and typed variants. This approach enforces invariants at compile time while producing production-ready structures for entities, value objects, and events.

Schema.Data wraps your schema to provide automatic structural equality and efficient comparisons for domain models. This enables reliable value object matching without manually implementing custom equality logic.

Expose constructors via Schema.decodeSync to enforce runtime validation and safe creation of domain entities. This guarantees that invalid states are rejected immediately during object instantiation.

Yes, pattern matching with Match.typeTags enables exhaustive variant handling for discriminated unions. This ensures every domain state like Pending or Active is processed without missing edge cases.

Use Schema.TaggedStruct to define event variants and Schema.decodeSync constructors to validate state transitions. This delivers a production-grade structure for event-sourced entities with clear exports and documentation.

Yes, you need an understanding of Effect schemas to define variants, apply Schema.Data, and pipe schema transformations. Familiarity with TypeScript discriminated unions is also required to structure the models correctly.
