Require one of two fields

Similar to this Yup issue: https://github.com/jquense/yup/issues/176

I’d like to conditionally validate at least one of n values are set. Yup and Joi solve this problem with a .when method.

Does Zod currently have a solution to this problem?

Feel the need to comment on this as I keep running into cases this is needed.

I have large schema that needs to require one or another field. A nested partial Zod object with superRefine works for this (as shown above).

What I want to be able to do however, is to do conditional requirement on 1 or 2 fields without making the entire object partial and while having access to all of the fields in the object.

Ex: I have a required enum that has two values: “ValueA” and “ValueB”

Upon “ValueA” then someOtherFieldA is required. Upon “ValueB” then someOtherFieldB is required.

There are also other required fields within the schema that should remain required without explicitly checking them in something like superRefine.

Is there any way to do this? Any plans for something like .when in Yup?
