covenixZod-powered decorators for Express

Typed routes, runtime validation, and accurate OpenAPI from a single source of truth.

One source of truth

The same Zod schema validates each request and produces its OpenAPI definition, so the two can never drift.

Zod parses, coerces, and defaults every request before your handler runs. Handlers receive clean, typed data.

Generate a swagger.json straight from your decorators via z.toJSONSchema — no build step, no config file, no codegen.
