Inline comments:
In `@docs/framework/preact/reference/functions/QueryErrorResetBoundary.md`:
- Around line 31-40: Import the ComponentChildren type in both Preact examples:
QueryErrorResetBoundary.md lines 31-40 and useQueryErrorResetBoundary.md lines
23-29. Add the type-only preact import to each source JSDoc example, then
regenerate both reference pages.
In `@packages/preact-query/src/HydrationBoundary.tsx`:
- Around line 29-30: Update the HydrationBoundary documentation to accurately
describe hydration timing: new queries are hydrated during render, while
already-cached queries are hydrated in useEffect; clarify that children render
unconditionally rather than implying they wait for all hydration.
Apply the same fix in
`@docs/framework/preact/reference/functions/HydrationBoundary.md` at line 28: The
generated function reference repeats the same timing claim.
Apply the same fix in
`@docs/framework/preact/reference/interfaces/HydrationBoundaryProps.md` around
lines 16 - 18: The generated props reference repeats the same timing claim.
In `@packages/preact-query/src/infiniteQueryOptions.ts`:
- Around line 88-100: Remove undefined from the
DefinedInitialDataInfiniteOptions.initialData type so initialData: undefined
cannot select the defined-data overload or expose data as defined. Apply the
same overload/type correction to infiniteQueryOptions in
packages/preact-query/src/infiniteQueryOptions.ts (lines 88-100) and
useInfiniteQuery in packages/preact-query/src/useInfiniteQuery.ts (line 25),
routing undefined values to the fallback overload instead.
In `@packages/preact-query/src/queryOptions.ts`:
- Around line 42-45: Update the documentation near the queryOptions overload to
state that deferred execution requires enabled: false, and that queryFn may be
omitted only when no fetch is needed or a default query function is configured.
Regenerate both affected Preact reference pages after updating the source
documentation.
Apply the same fix in
`@docs/framework/preact/reference/type-aliases/DefinedInitialDataOptions.md` at
line 34: The defined-data reference gives the same unsafe omission guidance.
Apply the same fix in `@packages/preact-query/src/infiniteQueryOptions.ts` around
lines 52 - 55: The infinite-query source description gives the same unsafe
omission guidance; its generated references also require regeneration.
In `@packages/preact-query/src/useMutationState.ts`:
- Around line 23-31: Update the useIsMutating, useMutation, and useMutationState
documentation examples so every hook call appears inside a valid Preact function
component or is explicitly marked as an in-component fragment. Apply the same
correction to both generated Preact reference pages while preserving the
existing example behavior.
In `@packages/preact-query/src/usePrefetchInfiniteQuery.tsx`:
- Around line 14-17: Update the documentation comment for getNextPageParam in
usePrefetchInfiniteQuery so it explains that the returned page parameter is
provided to queryFn through the query-function context as context.pageParam,
rather than as a positional argument. Preserve the existing description of
getNextPageParam inputs and its undefined/null no-next-page behavior.
Apply the same fix in
`@docs/framework/preact/reference/functions/usePrefetchInfiniteQuery.md` around
lines 18 - 20: The generated reference repeats the same incorrect
positional-argument description.
In `@packages/preact-query/src/useQueries.ts`:
- Around line 210-211: Update both useQueries documentation descriptions to
state that per-query options omit subscribed and use
QueriesPlaceholderDataFunction<TQueryFnData> for placeholderData; document that
combine changes the default result array to TCombinedResult, then regenerate the
useQueries reference documentation.
- Around line 217-222: Update the useQueries documentation to describe both
return branches: without combine it returns query results in input order, while
with combine it returns the value produced by combine as TCombinedResult. Apply
the same correction to the generated reference documentation.
In `@packages/preact-query/src/useQuery.ts`:
- Around line 134-139: Update the Post useQuery example to type postId as number
| undefined and use enabled: postId != null so zero remains valid; narrow or
guard the queryFn argument before calling fetchPost. Regenerate the useQuery
reference documentation to reflect the corrected example.
In `@packages/preact-query/src/useSuspenseQueries.ts`:
- Around line 165-167: Update both overload descriptions for useSuspenseQueries
to document skipToken as an unsupported queryFn value, alongside throwOnError,
enabled, and placeholderData; do not change runtime behavior.

Exclude undefined from the defined-data overload.
DefinedInitialDataInfiniteOptions.initialData includes undefined, and its overload precedes the fallback overload. Therefore, initialData: undefined can select the defined-data overload and expose data as defined. Remove | undefined from the defined-data contract or route undefined values to the fallback overload. Apply this to infiniteQueryOptions and useInfiniteQuery.

Preact hooks rules function components module scope hook invocation runtime error official documentation
💡 Result:
In Preact, hooks follow two fundamental rules to ensure they function correctly within the library's render system: 1. Top Level Only: Hooks must be called at the top level of your function component, not inside loops, conditions, or nested functions [1][2][3]. 2. Function Components Only: Hooks must be called exclusively from Preact function components or custom hooks, and never from regular JavaScript functions [1][2][4]. Runtime Error: "Hook can only be invoked from render methods" If you violate these rules, particularly by invoking a hook outside of a render context (e.g., at the module scope or inside a standard function), you may encounter the runtime error: "Hook can only be invoked from render methods" [4][5][6]. Enabling Debugging: This error is primarily surfaced by the preact/debug module [7][8]. By default, Preact's production build may not throw this specific error, which can lead to subtle bugs if hooks are misused [8]. To enable these helpful runtime validations and warnings, you should import the debug module at the very top of your application's entry file [8]: import "preact/debug"; Common Causes of the Error: Beyond calling hooks outside of components, this error frequently occurs due to the following configuration issues: - Multiple Preact Instances: If your application or its dependencies accidentally load multiple, conflicting copies of the Preact library (e.g., due to complex node_module resolution or library bundling issues), hooks may fail because the internal state tracking is split across different instances [6][9]. - Server-Side Rendering (SSR) Mismatches: In some SSR environments (like older versions of Next.js), issues with dependency deduping or mismatched imports between preact/compat and preact/hooks can trigger this error [5]. For reliable development, always ensure you are using hooks within functional components and include preact/debug during development to catch violations early [7][4][8].

- Around line 47-48: Update the HydrationBoundary return descriptions in
packages/preact-query/src/HydrationBoundary.tsx lines 47-48 and
docs/framework/preact/reference/functions/HydrationBoundary.md lines 28-29 to
state that cached queries are hydrated in the post-commit effect only when
hydrationIsNewer is true; keep the existing unconditional children rendering and
new-query render-time hydration descriptions unchanged.
In `@packages/preact-query/src/useQueries.ts`:
- Around line 266-269: Update the useQueries documentation comment to describe
placeholderData as accepting two parameters, previousData and previousQuery,
both typed as undefined, instead of calling it a single-argument function.
Regenerate the corresponding documentation in
docs/framework/preact/reference/functions/useQueries.md so both affected sites
reflect the same contract.

🎯 Changes
Adds JSDoc to
preact-query's public functions, components, and types (useQuery,useInfiniteQuery,useSuspenseQuery,useSuspenseInfiniteQuery,useSuspenseQueries,useQueries,useMutation,useMutationState,useIsFetching,useIsMutating,usePrefetchQuery,usePrefetchInfiniteQuery,queryOptions,infiniteQueryOptions,mutationOptions,QueryClientProvider,useQueryClient,QueryErrorResetBoundary,useQueryErrorResetBoundary,HydrationBoundary,IsRestoringProvider, plus the shared option/result types intypes.ts) so the TypeDoc-generated reference underdocs/framework/preact/reference/carries the same descriptions, parameter notes, return-value notes, and caveats the hand-writtendocs/framework/react/reference/docs already have.Where the React reference docs describe a
preact-query-owned parameter or return value (e.g. thequeryClientparameter, or the Suspense-variant caveats about cancellation not working), that text is ported and adapted. Where no example existed in the React docs, examples are adapted from working code inexamples/react/and translated to Preact where the pattern differs (QueryErrorResetBoundary/useQueryErrorResetBoundaryuse Preact's ownuseErrorBoundaryhook instead ofreact-error-boundary, which has no Preact equivalent).Every added
@examplewas pulled out and typechecked in isolation against the real exported types, which caught a few examples that looked right but didn't actually compile (wrong generic inference,getQueryDatawithout a type argument, a hook called outside a component). Overload-specific prose was checked against the actual type definitions rather than assumed, which caught a couple of copy-pasted sentences that didn't hold for the overload they were attached to (e.g. a@returnsclaimingstatuscould bependingon an overload whose return type statically excludes it).Options inherited from
query-core(e.g.staleTime,retry,gcTime) are out of scope here —generate-docs.tsexcludesquery-corefrom the TypeDoc entry points for all four generated frameworks, so JSDoc added there wouldn't currently render on these pages regardless. That's a separate, larger change to the shared TypeDoc pipeline.Regenerated
docs/framework/preact/reference/withpnpm run generate-docsto pick up the new JSDoc; no other framework's output changed.✅ Checklist
