RTK Query Cache Misuse

rtk-query-cache-misuse

RTK Query configuration and cache semantics get misapplied—using the wrong hook for server vs local state, misplacing polling options, and generating unstable/overbroad cache keys—so invalidations don’t propagate and data re-fetches or never refreshes as intended.

MATCHESSolution

You should really use tag validation to trigger your query endpoints to refetch upon any successful mutation. — onSuccess: async () => { await queryClient.invalidateQueries({ queryKey: ["vehicle.getVehiclesWithMakes"],. Tension: Both are less than ideal. Outcome: await queryClient.invalidateQueries({ queryKey: ["vehicle.getVehiclesWithMakes"], // <-- invalidates tag key });.

MATCHESSolution

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

MATCHESSolution

It will be 10 seconds after the previous request completes. — If `refetchInterval` is set to 10 seconds in `useQuery`. Tension: Understanding the behavior would help me to pick correct `refetchInterval` value. Outcome: The timer re-starts every time when data is put into the cache.

MATCHESSolution

Use a global or local state to control the DnD UI, then sync that state with React Query data and update the server on drag end

MATCHESSolution

useQuery has enabled option. Rewrite your custom hook like this: — return useQuery({. Outcome: enabled,.

MATCHESSolution

Call `trpc...useQuery` at the component top level, destructure `{ data }`, and then use `useEffect` (or derived rendering) to react to changes in `data`. Optionally control execution with query options (e.g., enabling based on `activeChildId`) instead of wrapping the hook call in `useEffect`.

MATCHESSolution

Setting `cacheTime: 0` solved it for me. — I was getting the same issue using `@tanstack/react-query@4.36.1`. Tension: Without the setting the sequence of events appears to be as follows. Outcome: In version 5, `cacheTime` has been renamed to `gcTime`.

MATCHESSolution

I think you can achieve that by using the `ensureQueryData` function. Tension: This way you first check on cache for the given key, and if nothing is found it runs the function and returns the result. Outcome: Another option could be to by making a custom hook use `getQueryData` to read the cache and if nothing is found it will return undefined so you could manage to call to your api.

MATCHESSolution

setting called `retryOnMount` — in either the global config or the config for the particular query. Tension: true by default. Outcome: The solution to your problem is setting `retryOnMount` to false in either the global config or the config for the particular query.

MATCHESSolution

Create a memoized router context object from the app context and call `router.invalidate()` in a `useEffect` when that memoized object changes, so `beforeLoad`/`loader` rerun with the updated data.

MATCHESSolution

If true, staleness checks for cached data will be bypassed, but missing data will be requested from the server. Tension: Default: false. Outcome: To force full offline mode, use --offline.

MATCHESSolution

you can set the revalidation duration to `0` — fetch("ENDPOINT", { next: { revalidate: 0 } }). Tension: to get new blog posts, you will have to wait until the cache is invalidated. Outcome: If you want to fetch the new blog posts when they're updated immediately.

MATCHESSolution

Use Next.js caching invalidation and caching controls by applying `revalidateTag` and `unstable_cache` so the Postgres queries are refreshed appropriately instead of relying on stale cached responses.

MATCHESSolution

Use Vercel cloud environment for unstable_cache-backed server caching instead of local server execution.

MATCHESSolution

in the Developer-Tools the "Disable Cache" in the Network-Tab is NOT checked — locally developing. Tension: otherwise the caching won't work while developing. Outcome: caching won't work while developing.

MATCHESSolution

Fetch the token with proper `await` (assign the resolved token value) and ensure the middleware pauses until the token is retrieved before allowing RTK-Query to continue. Also unconditionally `return next(action)` so middleware chaining and timing behave correctly.

MATCHESSolution

Call each RTK Query hook with the exact same query arguments (or none, if the endpoint takes none) that the fulfilled requests use, and ensure components read the correct hook data/selector result corresponding to those cache entries.

MATCHESSolution

Pass `pollingInterval` in the second argument of the query hook (e.g., `useGetDogsQuery(undefined, { pollingInterval })`, using `undefined` or `SkipToken` as the first argument when the endpoint takes no args).

MATCHESSolution

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

MATCHESSolution

Use RTK Query's `resultEqualityCheck` option in `selectFromResult` to compare the newly selected output with the previous cached output and return the old reference when the selected result is effectively identical, preventing unnecessary re-renders.

MATCHESSolution

Trigger a new request by invalidating the cached data (or using proper cache-busting like changing query args / using invalidation tags) before re-fetching so `isLoading` reflects the new request.

MATCHESSolution

Update the getSingleUser cache from within getUsers (e.g., using onQueryStarted in getUsers to dispatch api.util.updateQueryData for getSingleUser by the user id). Alternatively, ensure consistent tag types/ids between endpoints and manually prefill/replace the target endpoint’s cache so it’s treated as already fetched.

MATCHESSolution

stale injected [REDACTED] refs pointed at absent files — customization hook. Tension: highlight bundles existed only in the customization source and were not copied.

MATCHESSolution

Add extraReducers/addMatchers for each mutation endpoint (addTour, editTour, removeTour) to update `state.tour` on `matchFulfilled`, or use RTK Query tags and invalidation so queries refetch and state stays in sync.

MATCHESSolution

Use cache-busting query strings on the remoteEntry URL and avoid caching the remote entry

MATCHESSolution

Outcome: cache.clear().

MATCHESSolution

after each allocation that may trigger GC. Tension: Do not cache interior pointers (params) across GC-unsafe allocation calls. Outcome: Apply same fix pattern to sampled_data_continue.

MATCHESSolution

`query: { disableRefresh: true }`.

MATCHESSolution

Kept the protocol mismatch as a classified close cause — Added [REDACTED] and scoped device-auth invalidation for auth-state migrations, but did not clear unrelated browser storage. Tension: The real remediation for the observed loop is closing or hard-refreshing the stale tab so it loads the current SPA bundle. Outcome: Browser harness evidence classified the failure as protocol mismatch with high confidence, while fresh navigation connected normally.

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.
