useMutation in Context+Provider infinite calls

Hi all, thanks in advance for your time. I'm using react-router & tanstack query. I need a POST to get fired off upon App initialisation and I figured I could do that using a createContext and provider to then be able to access it a bit deeper down easily, that'd be useful. I am completely unable to get this to work or understand why I am getting infinite re-renders. I have tried everything chat gippity is suggesting and have googled as much as possible....

Is select callback only meant for data transformation?

I’m running into interesting side effects ( bad state updates ) when updating global stores within the select callback. Is it mostly meant to transform data?

What causes `queryClient.invalidateQueries()` to error when all requests are good?

Can `useQuery`'s result type figure out that all errors throw?

It's wonderful that the typings can reassure me that if status is neither pending nor error, I can rely on data being defined. It seems that it would be even better if they could somehow realize that because throwOnError is set, one only needs to eliminate pending in order to guarantee this state of affairs. Is this a deliberate design decision, am I doing things wrongly, or is it some sort of inherent TypeScript limitation?

Quick question about key equality and using it with gql

This might be obvious based on the docs:

Does this mean they are checked via the JSON serialised version for equality? So if I did:...

with nextjs what is the best way to architect your queries?

i have a nextjs front end with a nestjs backend with microservices. when deployed i realized that there are a myriad of apicalls that are just jhappening because htey either exist, or because the query keeps rendering on the timer. i understand i am still weak in my query approach, especially for an app that needs details on the front end. but at least how do i handle the querying properly when i am creating and updating information?...

SSE background Fetching while component unmount

So I am using react query to receiving streaming SSE api. The problem is this stream should not be canceled or stoped until a manual stop button is clicked. How can I make fetch SSE and complete it even though the component is unmounted? React query’s default behavior is canceling the quey if component is unmountrd. For the stop button, I am using query’s signal, but this makes react query to stop the streaming when component unmounted

Weird type bug when using `queryOptions` with `useQueries`

If you have a type where the only required key is name, the types of results in the combine function seems to be wrong. Any ideas on why this is? ```ts import { queryOptions, useQueries } from "@tanstack/react-query"; ...

default mutation onError fallback?

I would like to create a global useMutation error fallback, where it runs only if the specific mutation doesn't have its own onError handler, or if that error throws. I have set defaultOptions in QueryClient as so: ```ts const queryClient = new QueryClient({ defaultOptions: { mutations: {...

Reset Mutation State in onError Handler of MutationCache

Hello, guys! It’s possible to reset the mutation state inside the global onError handler for MutationCache?

using queryFn callback arguments breaks type inference (if placeholderData is a function)

Is this a known thing or potentially just a bug? It feels a bit like a bug. https://www.typescriptlang.org/play/?#code/JYWwDg9gTgLgBAbzgVwM4FMCKz1QJ4A0c2ueAwgDbDoB2MRAjjvgPJgzAQ2pwC+cAMygQQcAOQABGAENuMgMYBrAPRR00+TAC0TUmICwAKCPyuqeLvyVqdOAF44NdAHdizclVowAFAEojJmYW7vYoGCT43ghGcHCWeADS6HgAXHAA2mKoIuhJeGIAugQxcGAUGugAFhAUACa4ACLSMmlgagBu9gB8pR3FhrHxAGI0aX7diCWxajDIUDSTA7HLMJXAqACSNAK4qGliNMDy6BT5cNI8pnJTfCW8Rrz+xoZX5nAARsKKtBF4oWhYdxRErxPJpTLZEC5ZKFfqxMoVap1RrNaStDoTNrodpwuLuEZpC54GjyODeaRQADmvgm0SWsVeNXQADoKBBKeSqcz5J46E8bjM5gs6csVmtNttdvtDsdTmJzpcgjd7ksVY8jEA I'm not sure why the placeholderData callback cannot be supplied when I'm accessing the supplied value from the callback?...

Experimental streaming without prefetching in Next.js

I am using @tanstack/react-query-next-experimental and I understand that a new QueryClient is created for each server request. However, on a single frontend route, I have both the layout and the page, which are server-side, and they make the same request to the backend. Is there any alternative where I can cache these requests within the same frontend route?...

useInfiniteQuery blocks useQuery in modal

I have an infinite table using useInfiniteQuery. You can click each row to open a modal, which contains a useQuery to load additional data. My issue is that after initial load, it'll start loading the first next page, and while doing so, all useQuery calls in the modals are blocked. Upon completion, the modal loads immediately. Also, this doesn't seem to happen for subsequent next page loads. Does anyone know what might be going on? Am I not supposed to be calling useQuery from modals in...

OnSettled return void change in recent update causes error, how to solve?

We used to return a context on the onSettled to reset it to null (see screenshot) after the onSettled return type change to void | Promise<void>it started to throw an error. How can we achieve the same result now?

I want to use use, and use query mutate

I want to use use, fetch or start the on the server component and pass it to a client component and receive it with use but then when I mutate the data, in my mind there would be no key to invalidate but because use is handling the promise on the server? What would be a good pattern to be able to use mutate and use to start fetching the data right away? Or would doing this totally break the idea?...
