"Stuff" not present with Shadow Endpoints

Describe the problem

With the recent advent of shadow endpoints https://github.com/sveltejs/kit/issues/3532, it is now possible to move all database requests or other external loading to the .ts or .js file.

However:

• Shadow endpoints do not have an output of stuff like load functions.
• Therefore, a load function is still required when wanting to pass stuff to __layout.svelte files.
• While this doesn’t seem like a big deal, it is. When every page needs to pass stuff as an output - for example, for <meta> tags - then the entire point of shadow endpoints is defeated.

Describe the proposed solution

A possible solution could be to add an export of stuff to endpoint files. The complexity of this is unknown.

Alternatives considered

Require the user to provide a redundant load function on every page. However, this is suboptimal.

When every page needs to pass stuff as an output - for example, for <meta> tags - then the entire point of shadow endpoints is defeated.

Are you sure it’s that extreme?

The original issue for shadow endpoints includes an example of writing a load function easier than before when you can’t get away with not having a load function:

We could get the best of both worlds by feeding the props from the shadow endpoint into load …

For this situation, it’d be like:

<script context="module">
  /** @type {import('@sveltejs/kit').Load */
  export async function load({ props }) {
    return {
      props,
      stuff: { ... }, 
    }
  }
</script>

It is still the case, though, that you can’t send something from stuff to a shadow endpoint, but that isn’t what this issue explains.

Yes, I missed that you specified output in your description. So the only technical challenge would be merging any stuff from layouts (client-side) with stuff passed from shadow endpoints to the client. Which should be pretty straightforward.

I’ll update my comment to mention that it was a misunderstanding.
