rough outline for RSC prefetching

[phryneas]

This would enable manual endpoint prefetching from Server Components:

function Page() { return ( <PrefetchEndpoints baseQuery={baseQuery} run={async (prefetch) => { // immediate prefetching const promise1 = prefetch(api.endpoints.foo, 'bar') const promise2 = prefetch(api.endpoints.foo, 'baz') // and a "dependent endpoint" that can only be prefetched with the result of the first two const result1 = await promise1 const result2 = await promise2 prefetch(api.endpoints.foo, result1 + result2) }} > foo </PrefetchEndpoints> ) }

Drawbacks:

• as RTK currently doesn't have suspense, this will still render a loading state in SSR. We could add a "blocking" boolean option that could be set on the RSC side e.g. when a crawler request is detected to finish all requests before handing off to client components, so the SSR run would render the final data
