openapi-zodtyped-express

openapi-zodtyped-express keeps your endpoints documented using OPENAPI with just one single source of truth defined in the endpoints with zod schemas

• Generate OpenAPI API documentation
• Compile time validations - Infer Typescript static types out of the box
• Runtime validate each of your HTTP request with user-friendly error messages

All of this is done with a single higher-order-function used in the express endpoints. So you can just simply wrap your handler with the apiDoc(...) and initialize project via initApiDocs()

Important info

• every transform in a zod schema has to be piped with z.pipe() into a output validator like this: pipe(z.number()) as zods toJSONSchema cant get the output type of a transform.
• at the moment it is not possible to chain more zod on the zDual type (everything has to be done in the two internal schemas of ZDual)
