How to transform schema to conform to z.object() shape?

[chrisjansky]

Hi,

I am very fond of using valibot in nuxt and have migrated all validator logic to it from zod. The recent v3 of nuxt/content has introduced a schema requirement for content like this:

 goods: defineCollection({
      type: "data",
      source: "goods/*.json",
      schema: z.object({
        price: z.number(),
        ...
      }),
    })

I have raised an issue in nuxt/content to offer a more generic way to define schema without relying on a specific stack, ideally through https://standardschema.dev.

Realistically that’s not going to happen any time soon, so is there any way to work around that and give nuxt/content what it needs without maintaining two sets of validator schemas (valibot application-wide, zod for nuxt/content)?

Basically a transformer function that maps it to the shape of ZodObject.

Any help appreciated 🌈

Yes, it is possible to write such a function. Valibot schemas store any information in their objects. For example, via objectSchema.entries you can access the shape of the object schema.

Quick tip: You can put a schema in JSON.stringify(Schema, null, 2) and log it to the console to see its full structure.
