string type narrowing

[meadowsys]

hi!

I want to use zod (v3) to validate a string to be one of a few strings like this:

However, the type of that property (category) is still string:

I found a way to get the right type out of it using a transform afterwards:

This feels verbose and extremely repetitive though. Is there a better way to do this?

Is there a reason for not using enum ( which is what this is for )?

z.object({
  category: z.enum(["block", "sound", "lang", "misc"]).default("block")
})

I think that's exactly what I needed. Thanks!
