How to use sanityImage('string') in q.object?

[multiplehats]

Hey guys! Thanks for the awesome library.

One thing I can't figure out for the life of me is how to use sanityImage inside q.object().

import { type Selection, type TypeFromSelection, q, sanityImage } from 'groqd';

const gqField = q.object({
    s3_fileName: q.string().optional(),
    s3_id: q.string().optional(),
    createdAt: q.date(),
    image: sanityImage('image')
    // ^^ error: Type 'EntityQuery<FromSelection<{ readonly _key: ZodNullable<ZodString>; readonly _type: ZodString; } 
    // & { asset: EntityQuery<FromSelection<{ _ref: ZodString; _type: ZodLiteral<"reference">; }>>; }>>' 
    // is missing the following properties from type 'ZodType<any, any, any>': _type, _output, _input, _def, and 30 more.(2740)
})

const gqFields = {
    desktop: q.array(gqField),
    mobile: q.array(gqField),
} satisfies Selection;

export const gqPageFields = {
    id: ['_id', q.string()],
    name: q.string(),
    _updatedAt: q.date(),
    _createdAt: q.date(),
    images: q.object({
        one: q.object(gqFields),
        two: q.object(gqFields),
    })
} satisfies Selection;

export type PageFields = TypeFromSelection<typeof gqPageFields>;

Am I missing something?

Ahh – the Zod/TS errors are not at all comprehensible. The core issue, I believe, is that the fields inside q.object() are looking for zod-compatible types (like q.string(), q.number(), etc.), but the sanityImage helper actually returns back a Groqd EntityQuery instance (basically, a groq sub-query with associated schema). So, the sanityImage – as it stands – will only work inside of a .grab() statement.

I believe the rationale for returning a groqd query from sanityImage (instead of a more simple zod schema) is that to get image assets, you have to deref a field or two (I believe you have to do something like a asset→ call to get asset details. You can't do that without a groq query somewhere in there.

Not sure if it's feasible, but you could probably achieve this by refactoring to using nested .grab() calls instead of q.object().

@multiplehats any solution?
I'm facing the same issue.

I think I got it working after a little trial and error, using nested .grab() calls per @gksander's suggestion.

So instead of this (which is how I expected groqd to work):

q("*")
  .filter("_type == 'page'")
  .grab$({
    hero: q.object({
      heading: q.string(),
      image: sanityImage("image", { withAsset: ["base", "blurHash"] }),
      content: q.contentBlocks(),
    }),
    sections: q.array(
      q.object({
        heading: q.string(),
        image: sanityImage("image", { withAsset: ["base", "blurHash"] }),
        content: q.contentBlocks(),
      })
    ),
  })

I used this:

q("*")
  .filter("_type == 'page'")
  .grab$({
    hero: q("hero").grab$({
      heading: q.string(),
      image: sanityImage("image", { withAsset: ["base", "blurHash"] }),
      content: q.contentBlocks(),
    }),
    sections: q("sections")
      .filter() // turns it into an array query
      .grab$({
        heading: q.string(),
        image: sanityImage("image", { withAsset: ["base", "blurHash"] }),
        content: q.contentBlocks(),
      }),
  })

It seems to give me both the right data and types. Happy to hear suggestions if there are better approaches.
