FE/BE - Unite Them!

The article addresses 'model drift' — the divergence between frontend and backend conceptual models when teams are split by specialization, causing the frontend to think in API shapes rather than domain concepts. It argues the domain model, not the API contract or DB schema, should be the single source of truth, with UI, API, and persistence treated as projections of that model. The proposed solution involves defining an explicit domain layer with named domain objects, clear invariants, and shared terminology, then deriving API schemas from domain concepts.
