🎯 Changes

Adds JSDoc across packages/vue-query/src/ (18 of 19 files — index.ts is export-only), then switches docs/framework/vue/reference/ from 14 hand-written flat files to TypeDoc-generated output (functions/, classes/, type-aliases/, variables/, index.md) — the entry point registered in #11374. docs/config.json's vue framework section is rebuilt to match (14 → 41 entries), following index.md's generation order (Classes → Type Aliases → Variables → Functions, alphabetical within each group), same as react/preact/solid.

vue-query has no react-query source to port JSDoc from for 4 files with no react equivalent (useQueryClient.ts, vueQueryPlugin.ts, queryClient.ts, queryCache.ts/mutationCache.ts, utils.ts) — these were written directly from source, cross-checked against docs/framework/vue/installation.md/quick-start.md for accurate usage. All @examples use Vue 3 <script setup> — vue-query supports Vue 2.6+/3.3+ via vue-demi, but the composable API surface is identical either way, and this matches every existing vue-query doc.

Reactivity notes baked into the JSDoc, per docs/framework/vue/reactivity.md:

  • enabled tracks reactive dependencies automatically as a ref, a plain value, or a reactive getter (() => ...). queryKey reacts through a ref for the array itself, or refs and reactive getters as individual entries — the array itself can't be a bare getter. Other options are read once.
  • queryOptions/infiniteQueryOptions/mutationOptions have an extra getter-function overload (() => ({...})) beyond react-query's plain-object-only shape — confirmed via __tests__/queryOptions.test-d.ts/mutationOptions.test-d.ts. Documented as the pattern for keeping queryClient.invalidateQueries/fetchQuery reading current ref values instead of ones captured at options-creation time.

Examples brought to parity with react-query, matching the scenarios covered in packages/react-query/src/{queryOptions,useQuery,useInfiniteQuery,mutationOptions,useMutation,useQueries}.ts, adapted for vue-query's plain-object vs. whole-options-getter overload split:

  • useQuery: select, dependent queries (enabled), seeding from a cached list (initialData), keepPreviousData pagination, a staleTime reactive to a prop, and skipToken (requires a whole-options getter, since queryFn isn't itself reactive).
  • queryOptions: a parameterized factory combined with skipToken, matching the equivalent useQuery example.
  • useInfiniteQuery: a maxPages reactive example, skipToken, and IntersectionObserver-based infinite scroll (with onUnmounted cleanup).
  • useMutation: optimistic updates with rollback on error, and per-call callbacks vs. mutateAsync + Promise.all/Promise.allSettled.
  • mutationOptions: a mutationFn reactive to a prop, for both getter overloads (with/without mutationKey).
  • useQueries: a queryOptions + select typing pitfall example, matching react's.

Bug fixes found while writing the above:

  • queryClient.ts's invalidateQueries example passed a whole-options getter (() => ({ queryKey: [...] })) directly to invalidateQueries, which doesn't unwrap top-level getters — spreading it invalidated every query instead of the intended one. Replaced with a ref inside the queryKey array, which cloneDeepUnref does unwrap.
  • useMutation's parameter was named mutationOptions, colliding with the exported mutationOptions function and breaking its own {@link mutationOptions} JSDoc link (rendered as a broken in-page anchor). Renamed the parameter to options (and the internal computed variable to defaultedOptions to avoid re-colliding).
  • queryKey's JSDoc across queryOptions.ts, useQuery.ts, and useInfiniteQuery.ts (7 occurrences) claimed it could be passed as a ref, a plain value, or a reactive getter, same as enabled — but a bare getter on queryKey is a type error (MaybeRefDeep rejects a function at the top level, confirmed with a type-level probe). The first fix then overcorrected: it claimed individual queryKey entries can't be reactive getters either, which cloneDeepUnref's level === 1 && key === 'queryKey' branch and an existing test ('should allow getters for query keys') both contradict. Corrected wording: queryKey reacts through a ref for the whole array, or refs and reactive getters as individual entries — only the array itself can't be a bare getter.

What's lost, and how it was handled:

  • hydration.md's per-option field descriptions (shouldDehydrateMutation, serializeData, shouldRedactErrors, hydrate's defaultOptions) don't survive — dehydrate/hydrate are re-exported from @tanstack/query-core, which is excluded from every adapter's TypeDoc entry point (same tradeoff as react/preact/solid). Unlike react (which left this gap unfilled), this PR recovers it: the option descriptions are folded into guides/ssr.md's existing "Tips, Tricks and Caveats" section as a new ## dehydrate/hydrate options subsection, rather than resurrecting a flat reference/hydration.md page (which would go stale — the framework's convention is generated-only under reference/).
  • useQuery.md's vue-specific caveat on select ("since a Vue setup() function only runs once per component instance, an inline select function already has a stable reference") isn't something a mapped-type option object (QueryOptions) can carry per-field JSDoc for — added to queryOptions.ts's QueryOptions type-level JSDoc instead, which every options type (UndefinedInitialQueryOptions, DefinedInitialQueryOptions, etc.) intersects with and links back to from its own reference page.
  • Per-option field descriptions for options vue-query doesn't re-declare itself (retry, gcTime, networkMode, select's core behavior, etc.) don't survive, since @tanstack/query-core is excluded from every adapter's TypeDoc entry point and these fields live on core types — this mirrors the react/preact/solid tradeoff exactly, not a new vue-specific loss.
  • Fixed two links in overview.md/reactivity.md still pointing at the old flat reference/useQuery path.

All 13 other deleted pages (infiniteQueryOptions.md, mutationOptions.md, queryOptions.md, useInfiniteQuery.md, useIsFetching.md, useIsMutating.md, useMutation.md, useMutationState.md, usePrefetchInfiniteQuery.md, usePrefetchQuery.md, useQueries.md, useQuery.md, useQueryClient.md) were verified line-by-line against their replacement pages — no other content loss found.

📝 Walkthrough

Walkthrough

The PR expands Vue Query API documentation with package JSDoc, categorized reference pages, updated navigation links, and SSR hydration guidance. It removes superseded uncategorized pages. Runtime behavior remains unchanged except for the useMutation parameter naming and internal variable rename.

Changes

Vue Query documentation refresh

Layer / File(s) Summary
Package API JSDoc
packages/vue-query/src/*
Adds JSDoc for Vue Query composables, overloads, types, caches, clients, utilities, and plugin options.
Function reference pages
docs/framework/vue/reference/functions/*
Adds categorized reference pages for query, mutation, infinite-query, prefetch, state, client, and option functions.
Class and type reference pages
docs/framework/vue/reference/classes/*, docs/framework/vue/reference/type-aliases/*, docs/framework/vue/reference/variables/*
Adds references for Vue-aware classes, option and result types, and VueQueryPlugin.
Reference navigation and guides
docs/config.json, docs/framework/vue/reference/index.md, docs/framework/vue/{overview.md,reactivity.md}, docs/framework/vue/guides/ssr.md
Groups API navigation by category, updates reference links, removes obsolete pages, and documents dehydrate/hydrate options and cache overwrite behavior.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to e434e

The Vue Query reference refresh improves API guidance, but several examples can mislead copied implementations or retain browser observers after component removal. The package runtime is unchanged; correct these documentation issues before relying on the new examples as canonical guidance.

minimal, and validate.

Inline comments:
In `@docs/framework/vue/reference/classes/QueryClient.md`:
- Around line 8-11: Align the QueryClient overview with the published method
signatures: either remove the claim that every filter-accepting method supports
MaybeRefDeep and revise the invalidateQueries example, or update the signatures
for cancelQueries, invalidateQueries, refetchQueries, removeQueries, and
resetQueries to accept MaybeRefDeep and regenerate the documentation. Keep the
overview and rendered API types consistent.

In `@docs/framework/vue/reference/functions/queryOptions.md`:
- Line 144: Update the useQuery call to pass the postOptions getter itself
rather than invoking postOptions(), preserving reactivity when postId changes.
Keep the existing postOptions() invocation for the imperative invalidateQueries
call.

In `@docs/framework/vue/reference/functions/useIsFetching.md`:
- Line 7: Update the TypeScript reference signatures for useIsFetching in
docs/framework/vue/reference/functions/useIsFetching.md line 7, useIsMutating in
docs/framework/vue/reference/functions/useIsMutating.md line 7, and
useQueryClient in docs/framework/vue/reference/functions/useQueryClient.md line
7 to mark their defaulted first parameters fetchingFilters, filters, and id as
optional; make no other changes.

In `@docs/framework/vue/reference/functions/useMutation.md`:
- Line 62: Update the mutationOptions reference in the useMutation documentation
to link to the generated mutationOptions.md page instead of the incorrect
`#usemutation` anchor, preserving the surrounding wording.

In `@docs/framework/vue/reference/functions/useQueries.md`:
- Line 78: Update the v-for list key in the postQueries example to reference the
declared props object, using props.ids[index] instead of ids[index].

In `@docs/framework/vue/reference/type-aliases/QueryOptions.md`:
- Around line 12-19: Update the query options documentation around queryOptions
and useQuery to distinguish property-level reactivity from whole-options
getters: state that getters returning the complete options object are
re-evaluated and can update fields such as staleTime, retry, and select. Clarify
that select remains stable only when created once in setup(), while an inline
function created inside a whole-options getter may change on each evaluation.

In `@packages/vue-query/src/mutationOptions.ts`:
- Around line 28-30: Instantiate useMutationState once outside the computed
getter, then have the isCreatingPost computed value derive from the returned
ref. This prevents repeated mutation-cache subscriptions when the getter re-runs
while preserving the existing mutation filters and boolean result.

In `@packages/vue-query/src/queryClient.ts`:
- Line 55: Update the isRestoring documentation in QueryClient to state that it
defaults to false and becomes true while a configured persister restores the
cache; remove the inaccurate undefined behavior description.

In `@packages/vue-query/src/queryOptions.ts`:
- Line 273: Update the example import alongside queryOptions and useQuery to
include useQueryClient, matching its usage in the example.
- Around line 25-26: Update the TQueryData template documentation in
queryOptions.ts to state that it defaults to TQueryFnData and may be configured
independently; remove the claim that select narrows TQueryData.

In `@packages/vue-query/src/useInfiniteQuery.ts`:
- Around line 75-76: Update UseInfiniteQueryOptions so queryKey accepts reactive
getters nested within its MaybeRefDeep type, matching cloneDeepUnref’s runtime
behavior. Ensure the related queryKey documentation accurately reflects the
supported type-level API while preserving existing ref and plain-value support.

In `@packages/vue-query/src/useQueries.ts`:
- Line 275: Update the example template’s key expression to reference the
declared props binding, changing the undefined ids reference in the postQueries
v-for to use props.ids[index].

In `@packages/vue-query/src/useQuery.ts`:
- Around line 105-106: Update the useQuery documentation to remove the sentence
claiming that non-queryKey options are read once, while preserving the
explanation of reactive getters and queryKey behavior.

🌐 Web query:

site:tanstack.com/query/latest/docs/framework/vue/reference useIsFetching useIsMutating useQueryClient optional parameters

💡 Result:

In TanStack Query, the hooks useIsFetching, useIsMutating, and useQueryClient share a common pattern regarding optional parameters, specifically for managing the QueryClient instance [1][2][3]. useIsFetching This hook returns the number of queries currently fetching in the background [1]. It accepts an optional configuration object as its first parameter with the following properties: - filters: An object of type QueryFilters, used to narrow down which queries to track (e.g., by query key) [1]. - queryClient: An optional QueryClient instance. If not provided, the hook will use the QueryClient from the nearest context [1]. useIsMutating This hook returns the number of mutations currently in progress [2]. It accepts an optional configuration object as its first parameter with the following properties: - filters: An object of type MutationFilters, used to narrow down which mutations to track [2]. - queryClient: An optional QueryClient instance. If not provided, the hook will use the QueryClient from the nearest context [2]. useQueryClient This hook returns the current QueryClient instance available in the context [3]. It accepts an optional parameter: - queryClient: You can optionally pass a specific QueryClient instance to this hook. If provided, the hook returns that instance; otherwise, it returns the one from the nearest context [3]. In all three cases, if a specific QueryClient is not provided as an argument, the hooks automatically resolve the correct instance from the TanStack Query context [1][2][3].

Mark defaulted parameters as optional.

useIsFetching and useIsMutating default their first parameters to {}. useQueryClient defaults id to ''. Add ? to fetchingFilters, filters, and id in the three Vue reference signatures.

Type queryKey getters in UseInfiniteQueryOptions. cloneDeepUnref evaluates getters inside queryKey at runtime, but UseInfiniteQueryOptions types the property with MaybeRefDeep, which rejects a getter. The three comments currently document a runtime-supported form that TypeScript does not accept.

Preserve the cached list timestamp.

When staleTime is non-zero, omitting initialDataUpdatedAt timestamps the cached detail data with Date.now(). The detail query can then skip its mount fetch. Add initialDataUpdatedAt from the list query state.

Proposed fix
   initialData: () =>
     queryClient
       .getQueryData<Array<Post>>(['posts'])
       ?.find((post) => post.id === props.postId),
+  initialDataUpdatedAt: () =>
+    queryClient.getQueryState(['posts'])?.dataUpdatedAt,
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
