Greetings! I don't understand why it's generating two fetches when I render this component. Any ideas? It's supposed to do just 1 fetch, not 2 T.T

hm where do you have a query with the key tags? seems to be a different one. It's also inactive, maybe it's from the previous page? ah you mean two network requests

edard3v 🦀OP•2w ago

2 net

Jasmin•2w ago

and both are GET requests? one isn't an option request?

edard3v 🦀OP•2w ago

GET both

I don't understand what could be happening. I don't know if it has anything to do with the tanStack configuration with localStorage. I changed from session Storage to localStorage and it seems to do only 1 fetch when reloading the page, but if I navigate it does 2. I don't understand Well, I made a build and in build it only does 1 fetch xD... Now I don't know if it's Astro or Solid hahaha or TanStack... crazy @Jasmin

hm interesting

edard3v 🦀OP•2w ago

It works fine in production, but it seems really strange to me what's happening in dev.

Jasmin•2w ago

I don't know if tanstack query does something different in dev mode

edard3v 🦀OP•2w ago

Well, I was scared. It doesn't seem serious, if it works in production xD

a dev different from production is the source of all evil https://github.com/solidjs/solid/issues/2454 the original issue, is not the same as yours but it looks like the double fetching is a repeating pattern in solid see this comment https://github.com/solidjs/solid/issues/2454#issuecomment-2744431865

I've never understood why they do it. It's like React's strict mode, I don't see the point xD, but hey, who am I? The same old thing.

zulu•2w ago

interesting maybe they do that for the same reason react does, didn't think about that

edard3v 🦀OP•2w ago

When I use re-r-re-re-re-re-re-re-re-re-re-react I always remove it xD

It's like React's strict mode, I don't see the point xD.

It literally was introduced to stop people fetching in useEffect. https://github.com/facebook/react/issues/24502#issuecomment-1118867879 Ryan Florence went on at length about it at Reactathon 2022 “When to fetch”. Using React Query was actually one of the proposed solutions.

a dev different from production is the source of all evil

Try to explain to everyone that their desire for DX is the source of all evil; HMR doesn't contribute anything to production but is the greatest reason that dev and production are different.

Just as an aside: The TanStack example makes liberal use of Suspense which is likely preferrable to

{ query.isLoading && <Loading class="absolute_center" /> }

{ query.isLoading && <Loading class="absolute_center" /> }

and

{ query.isError && <ErrIcon class="absolute_center" /> }

{ query.isError && <ErrIcon class="absolute_center" /> }

is likely better served with Show: So I imagine something along the lines of:

<article class={css.cards}>
  <Suspense fallback={<Loading class="absolute_center" />}>
    <Show
      when={!query.isError && query.data}
      fallback={<ErrIcon class="absolute_center" />}
    >
      {(data) => <div>{data().id}</div>}
    </Show>
  </Suspense>
</article>

<article class={css.cards}>
  <Suspense fallback={<Loading class="absolute_center" />}>
    <Show
      when={!query.isError && query.data}
      fallback={<ErrIcon class="absolute_center" />}
    >
      {(data) => <div>{data().id}</div>}
    </Show>
  </Suspense>
</article>

Controversial xD I think I read it better as I have it.

ryansolid•2w ago

I haven't had a chance to look at that one yet but I wouldn't say this is something I've commonly(ever?) seen in the past 5 years we've been doing SSR. Just clarify I imagine this behavior is not expected.
