Shared schema and contracts
Define each domain model once as a Zod schema. SwallowKit uses it to generate TypeScript types, validation, BFF routes, backend handlers, and API contracts — so they stay consistent as the application grows.
Keep your Next.js frontend, BFF, Azure Functions backend, and infrastructure aligned through shared Zod schemas.

In full-stack applications, the same domain model is repeated across frontend forms, client validation, BFF types, backend DTOs, API contracts, database entities, and infrastructure config. These definitions drift apart as the project grows.
AI tools can generate code quickly, but they do not automatically maintain consistency across these layers. Frameworks can hide complexity, but production applications still need explicit architecture that developers can read and change.
SwallowKit addresses this by placing a shared Zod schema at the center and generating the surrounding application structure from it. It is a scaffolding toolkit — not a runtime framework. Generated code can be read, edited, and replaced.
