Svelte Query SSR doesn't work with ORPC

I try tanstack query svelte with ORPC. The SSR Example in the repo works but the SSR does not work when I use with ORPC. When I console log the query.isLoading, it log true on the server but it render the UI without waiting the prefetch query, I guess. I also await the prefetch query and also use the fetch from svelte as well. Did anyone got that issue? ```ts export const load: PageLoad = async ({ fetch, parent }) => { const orpc = getApiClient(fetch); const { queryClient } = await parent();...

Caching response in layout files

Hey! I’ve set up a main +layout.svelte file where I fetch my data. The problem is that every time I navigate to another subpage that uses this layout, the data gets fetched again. Is there a way to configure Svelte Query so that it caches the data in the layout instead of refetching it on each navigation?

Bug: Making a query returns `process not defined` on CSR application

Problem: I'm trying to implement SvelteQuery into our Svelte application which is using Routify for routing. We have only client side rendering and I am wrapping the app with QueryClientProvider and trying to make a request with createQuery. When I do that I get the error ReferenceError: process is not defined. This seems like a Node error, and we don't do any server side rendering for now. I tried changing imports from @tanstack/svelte-query to @sveltestack/svelte-query so that I use sveltestack's library and when I use that one it works, so I don't see anything specific from our app being a problem. ...
