Hook Misuse in Data Fetch

hook-misuse-in-data-fetch

A recurring shape where React routing hooks (e.g., usePathname/useSearchParams) are read or invoked as if they were plain values or callable from non-hook helpers, leading to undefined semantics or hook/runtime errors during async fetches.

MATCHESSolution

Refactor so that hooks are called only inside the custom hook or at the component level, and return plain functions that do not call hooks (e.g., compute/set needed state without invoking hooks in the returned callback). Alternatively restructure the custom hook to expose non-hook handlers or move the hook invocation to component initialization and pass the resulting setters.

MATCHESSolution

handle a scenario when the code is fine but backend went offline — prefetching data with usePrefetchQuery. Tension: prefetch works.

MATCHESSolution

Function components cannot be given refs. — when I'm trying to use this as a slot for other MUI component. Tension: Attempts to access this ref will fail. Outcome: Did you mean to use React.forwardRef()?

MATCHESSolution

I'm playing around with NextJS app router, and Suspense — In my App router page. Tension: this suspense boundary won't do anything.

MATCHESSolution

I try putting a setName(data.name) inside a useEffect that runs only when "isLoading" changes, and it works — edit/change the "name" retrieved by the query. Tension: I would think there is a better and more clean way to do it. Outcome: use a `useEffect` hook to "synchronize" a React state to an external source.

MATCHESSolution

Update to pass the fetching function as the mutation's `mutationFn` property. — `const { mutate } = useMutation({ mutationFn: (title) => axios.post("/api/posts/addPost", { title }),. Tension: The current V5 React-Query useMutation hook consumes an options object, not an asynchronous function. Outcome: const { mutate } = useMutation({ mutationFn: (title) => axios.post("/api/posts/addPost", { title }), onSuccess: (data) => { console.log('Post added successfully:', data); }, onError: (error) => { console.error('Error adding post:', error); }, });.

MATCHESSolution

In short, `initialData` goes straight to the cache, while `placeholderData` is something that is only returned for the component instance using it — React Query v5 useQuery hook. Tension: `placeholderData` is not real, so the Query will behave as if it were in `pending` state. Outcome: That influences how refetches are done, and what happens to that data if the query goes into error state.

MATCHESSolution

return response.data; — queryFn: async () => { const response = await fetchMaterial();. Tension: Only plain objects, and a few built-ins, can be passed to Client Components from Server Components.

MATCHESSolution

Remove the catch handlers or re-throw the error after handling it so useMutation can trigger onError

MATCHESSolution

Move usePathname() into the component or a custom hook, pass the pathname into getData(), and keep fetchData as a plain async function

MATCHESSolution

Wrap you components that rely on React Query data — React Query data. Outcome: with Suspense and HydrationBoundary.

MATCHESSolution

use hash-based routing — react + tanstack router + github pages. Tension: The default "browser" routing will exhibit the behaviour you describe.

MATCHESSolution

Add a force reload flag — Next.js App Router API route. Tension: ensure functions aren't reused. Outcome: export const dynamic = 'force-dynamic'; export const revalidate = 0;.

MATCHESSolution

Use fetch instead of Axios

MATCHESSolution

Recommended way is to `useSearchParams` ref — when doing `npm run build`. Tension: trying to use: `useRouter`, `usePathname`. Outcome: Locally it works fine with `npm run dev`.

MATCHESSolution

Use React.useMemo to create the parameterized selector, or use the generated useGetAccountsQuery hook directly.

MATCHESSolution

Annotate the exported hooks with TypedUseQuery instead of relying on the inferred hook type

MATCHESSolution

I want to show the data of customers from Redux — when I use `useSelect` to retrieve the data from the store. Tension: entries.map is not a function. Outcome: retrieve the data from the store.

MATCHESSolution

An async function was passed to useActionState.

MATCHESSolution

There isn't any `getData` endpoint declared so there will not be any `useGetDataQuery` hook generated. — export const { useGetDataQuery } = apiSlice;. Tension: only `useGetWines-X` hooks will be generated. Outcome: export const { useGetWinesQuery } = apiSlice;.

MATCHESSolution

const { data } = await thunkApi.dispatch( userApi.endpoints.login.initiate(credentials); );. Tension: I want to use `fetchBaseQuery` in the API call. Outcome: You can initiate an endpoint directly.

MATCHESSolution

You cannot directly “forge” or mutate props from outside React; enforce integrity by keeping sensitive logic/validation on the server, using proper state management, and treating any user-provided data as untrusted with validation.

MATCHESSolution

`useCallback` needs to be used — to be used as a callback and thus prevent the unnecessary re-renders. Tension: `memo` can't prevent `ExpensiveComponent` from being re-rendered. Outcome: const handleRender = useCallback(() => {...}, []);.

MATCHESSolution

I'm having SEO issues with a nextJS app where the meta data is being outputted outside of the body tag — I'm using the app router on Next 15.2.3. Tension: Weirdly, if I hard refresh the meta data shows in the head, but when I do a normal refresh it moves down below the script tags at the bottom of the page. Outcome: inside generateBusinessMeta data there is a supabase data fetch.

MATCHESSolution

Call all hooks unconditionally at the top of the component (e.g., move useParams() above the ready/user checks) and only render conditional UI afterward; optionally use nested routes for subpages instead of relying on conditional logic.

MATCHESSolution

Keep using Mantine's `useForm` for validation and submit the form via react-router-dom by using `useFetcher` (or otherwise imperatively calling the action) so Mantine can validate first, then submit a proper `FormData` payload (ensuring inputs include the required `name` fields or manually constructing `FormData`).

MATCHESSolution

const { user } = useAuth(); — PrivateRoute. Tension: the `Outlet` is being rendered instead of the `Navigate` component. Outcome: return user ? : ;.

MATCHESSolution

`nock@beta` support for `fetch` — Node 18+: make nock work native fetch. Tension: We have introduced experimental support for `fetch`.

MATCHESSolution

case "CallbackRouteError": return { error: "Invalid credentials!" } — in my `login.ts` server action in the switch case clause. Tension: to return the correct errors. Outcome: bypass this error.

MATCHESSolution

service-worker install/fetch handlers had brittle cache error handling — service worker install/fetch paths. Tension: brittle cache error handling. Outcome: tolerant precache and explicit offline responses.
