Input and Response Types

[samchungy]

Zod Schemas have some methods which generate different input and output types.

We need to add some logic to tell us we're in input generating mode versus output generating mode. This will help us generate parameters versus responses.

eg. with a transform we have an input type available but not an output type.

eg. z.string().transform((str) => str.length) we can tell we have a string input but not an output as we cannot infer the type of the transform.

Likewise with preprocess we can't tell what input we have but we know the output.

Same logic can be applied with .pipe
