Best way to infer loaderData types from a route?

[merthanmerter]

When I want to type props based on another route’s loader data, I’m currently doing

initialValues?: typeof SomeRoute.types.loaderData

Is there a more concise or alternative way to infer the type?

If not, what do you think about using a helper type like this?

type LoaderData<T> = T extends { types: { loaderData: infer L } } ? L : never;

Then it could be used like:

initialValues?: LoaderData<typeof SomeRoute>;

Would love to hear if there’s an official recommendation or if people are doing something similar!
