How to discriminate queryCollection results?

[adrianrudnik]

What would be the best way to discriminate between the results of multiple queryCollection calls?

Basic usage for me is: I have many different kind of types of documents, like guides, workarounds, lists, notes, each one its own set of markdown files with only a single shared schema field: code which is unique per document, but the rest of the schema is different otherwise.

Normally I would add a literal discriminator field to the union of types, but z.literal() does not seem to be supported for the defineCollection as it throws me a Unsupported Zod type: ZodLiteral .

So instead of simply determining the type prior going into details like

<div v-if="page.tax === 'guide'">{{ page.guide_prop_a }} ... {{ page.guide_prop_b }}</div>

I now have to focus on each attribute like

<div v-if="'guide_prop_a' in page">{{ page.guide_prop_a}}</div>

Any other approach so far has led to the typescript service/validation screaming at me.
