Validation

Validate requests and responses with any Standard Schema-compatible library.

Nooh’s validation system is built on Standard Schema — a shared interface that Zod, Valibot, ArkType, and others all implement. You pick your library; Nooh generates the correct TypeScript types for the request context and response body.

How Nooh uses Standard Schema and which libraries are supported.

Request validation

Validate JSON bodies, form data, query strings, headers, and cookies.

Response validation

Validate and type the response body at runtime.
