Enhancement Route.MetaFunction type

[Heyrows]

Context:

version: 7.9.2 of react-router in an hydrogen project.

Hi 👋,
I have recently started playing with generated types for react-router and I have noticed the following.

In the following code

import type { Route } from './+types/....';

export const meta: Route.MetaFunction = ({ loaderData }) => ...

export async const loader: A = ...

export async const clientLoader: B = ...

It seems that the generated types expects that the argument LoaderData of the meta function is typed A | B.
I can only assume it has been made so it handles cases such as having only a clientLoader in a file.

My suggestion
I would expect loaderData to be typed

• A only if there is a loader function
• B only if there is a clientLoader function
• A if both are defined.

It would avoid handling cases where property X is defined in the loader but not in the clientLoader, leading to extra code that is useless at runtime.

N.B
I am fairly new at using react-router extensively so forgive me if I missed part of the documentation or a use case I didn't think of.
