Using the key of string enum using nativeEnum?

[hls-app]

So I have been using this Country enum and wondering if we can validate the keys instead of the value?

Currently, the nativeEnum validates the value and could not find an option to make it validate the key instead.

Currently using this as I cannot flip the enum just for Zod

z.string().length(2).regex(/^[A-Z]{2}$/, 'Invalid country code').nullable()

[nabil-rady]

This how I did it

z.enum(Object.keys(Enum) as [keyof typeof Enum, ...(keyof typeof Enum[]])

Let me know if you have a better idea than this.
