Resolving references in the structure builder for constructing a URL in Sanity.io.

Last updated: Mar 4, 2022
Hi!
I'm setting up a preview iframe pane, and creating a 
resolveProductionUrl
function, like in many of the guides suggests. I have done it before, and it works great. Usually.
However, now I want to construct the URL from a referenced field. I have an 
article
schema type, that has a reference to a 
category
type. The URL is basically 
${article.category.slug.current}/${article.slug.current}
. However, the doc passed by the 
S.view.options({ url: resolveProductionUrl })
function (where S is the structure builder) doesn't resolve references (so 
article.category
is just a regular ref object.
How can I resolve that doc?

What does your 
resolveProductionUrl
function look like?

It's pretty basic

export const resolveProductionUrl = (doc: any) => {
  const host = window.location.href.includes("localhost")
    ? "<http://localhost:3000>"
    : "<https://production.domain>";

  return `${host}/${doc.category.slug?.current}/${doc.slug.current}?preview=${process.env.SANITY_PREVIEW_SECRET}`;
};
However, 
doc.category
is just an object containing a 
_ref
to the category ID

Ah got it! So, set up that way, your function has no way to resolve the category reference. You'll have to import the client:
import client from "part:@sanity/base/client"

const sanityClient = client.withConfig({apiVersion: '2021-03-25'})
Then fetch the category values before returning the url.

Oh that’s how that’s done within the studio. Are there docs about the studio client I missed somehow?

Thanks!

I know it exists in the docs, but I can't remember where. I'll look around for it.

Well, don’t spent your time doing that. I’ll find it myself. Thanks for showing me though 😍
