Refactoring queries

I'm working on a big enterprise project that grew out of a startup. Just like any other startup, it has all the same problems—fast-growing, constantly changing requirements, tons of code, different architectural approaches, etc. With a growing codebase, I started to observe query key collisions, and I want to clean this mess up, as it's becoming harder to maintain and catch bugs. I was looking into 2 possible solutions: 1. query-key-factory 2. query options To give you an example of the code, everywhere in the project we use custom hooks like this one:...

Looking for work as a Frontend developer

As an Angular/Vue.js developer with 6 years' experience, I craft fast web apps using RxJS/NgRx and Composition API/Pinia for state management. Modern TypeScript/JavaScript drives these implementations, paired with MUI/Tailwind CSS for polished interfaces. Seamless REST/GraphQL API connections bridge to backends, occasionally enhanced with Node.js/.NET support and SQL/MongoDB databases. Recent projects incorporate AI tools like OpenAI/ChatGPT for smart features in Angular/Vue environments....

Does the queryFn need to have a stable reference?

When providing useQuery with a queryFn, will the query fire each time it receives a new queryFn reference? E.g., when defining a function inline: ```ts function useFoo() { const queryFn = () => Promise.resolve("ok");...

Next.js (16.0.3) | useMutation | An unexpected response was received from the server.

Hey guys, I am trying to move from next 15.3.4 -> 16.0.3 and react 19 -> 19.2 and I have been experiencing some errors that I can't figure out how to solve. What was working before the version bump, now throws the error you can see commented out and skips the onSuccess. The only way I have managed to bypass the problem is to switch to onSettled but that doesn't feel like the right solution...

Infinite query's fetchNextPage manual hasNextPage check

Hi, I was wondering why fetchNextPage doesn't automatically check if there is a next page to fetch. For example the docs give this example. I get why isFetching is not automatically checked but I can't find any logical reason for the hasNextPage not automatically be included in the fetchNextPage. ...

Idea: add pendingMs / minPendingMs for mutation isPending

Hello! I was wondering if it could make sense to add pendingMs and minPendingMs (similar to what exists in TanStack Router) for the isPending state (or more likely a derived state, I don't know) in TanStack Query. For context, I generally avoid optimistic updates (complexity and other reasons lol), so I use the onSuccess callback of mutations to update the data. While a mutation is in progress, I disable parts of my UI (like reduce opacityor show a loading state) so the user knows something is happening....

Is there a reason MutationObserver.#updateResult is private?

Hey! I made a MobX adapter for TanStack Query v4. It works great - we have a MobxQuery, MobxMutation and MobxQueries that are same as the corresponding React hooks, reactivity works, everything is well. When trying to upgrade to v5, MobxMutation no longer works. The reason is, at some point in the lifecycle, I called the "private" function updateResult on my local MutationObserver instance. In v4 it was just a Typescript "private" so calling it worked on runtime. Not optimal but fits my needs. Now in v5 it's actually nonexistent outside of the class. My adapter behavior relies on calling this. ...

React query + TanStack forms for immediate mutations instead of on submit

Hi, I have a form where I would like to save the edits to the fields immediately (or in case of text inputs with a debounce) to the server instead of when the user hits submit. So basically this should work like an autosave feature. The tanstack form onChange + onChangeDebounceMs api seems ideal for this. How should I handle rapid API calls that lead to potential race conditions and how do I notice when the form state and server state get out of sync?...

Is this best practice or what is the best way to achieve this?

What I want; - fetch all data in the beginning as batch and only once - merge batch with initial data, that needs to load immedtiately, because fetched data belongs with initialdata , but initialdata needs to be present immediately - provide a o(1) lookup of each spice, individual data, to make it easy and accessible to set new data, check/look it up and get it, I can’t use maps, since they don’t serialize well and objects are clunky. ...

Calling dependent queries declaratively and imperatively

Hi, is there any good way to be able to call dependent queries both via hooks and imperatively? For independent queries, it's great that you can do this ```ts const projectsOpts = (userId: string) => ({ queryKey: ['user', userId, 'projects'], queryFn: () => fetchProjects(userId),...

Is it bad practice to use useMutation or useQuery inside a service class (React Query + TypeScript)?

I’ve built an authentication flow using React Query and TypeScript, and everything works fine. But I’m not sure if calling useMutation() inside a service class is considered a bad practice, instead of defining it directly inside the React component. Does this approach break any React rules ?...

Benchmarking experimental persist plugin

The experimental_createQueryPersister seems to be slower compared to the <PersistQueryClientProvider /> one. I get that experimental_createQueryPersister restores from disk when needed, while <PersistQueryClientProvider /> restores the whole cache over RQ's in-memory cache. I am asking if there are any known methods of benchmarking the plugin. I am trying to use op-sqlite's KV storage too, so I want to rule out the possibility of the KV storage being too slow....

Performance Question. useQuery in each component or pass the data in as a prop to each?

From a performance standpoint, if I have a list of 500 items that all need a big object that is in the query cache, is it better for me to have a useQuery call in each of the 500 components or have one call in the parent and pass the whole object as a prop to each of the 500 items.
