🎯 Changes

Six svelte-query reference pages rendered with no description at all — Defined in: was followed straight by a heading. The cause was one of three, and each needed a different fix:

Summary sentence missing (4 pages). createQuery (both public overloads), createQueries and useIsFetching already document every parameter and carry an @example, but their JSDoc opened with a tag, so TypeDoc had no summary to render. Each gained one leading sentence; the existing tags are untouched.

No JSDoc at all (2 pages). useIsRestoring and useQueryClient had none, so they got a summary plus @param/@returns/@example:

  • useIsRestoring returns Box<boolean> here, not the plain boolean React returns, so the docs say to read .current. It also notes the value is false outside a PersistQueryClientProvider, which is what getIsRestoringContext falls back to.
  • useQueryClient documents the @throws case, matching the error getQueryClientContext raises when the component isn't wrapped in a QueryClientProvider.

Overloads without JSDoc (createInfiniteQuery). Only the third of its three public overloads was documented. A page renders from its first signature, so adding a summary to the third one alone left the page blank. Both remaining overloads now carry a full block, each stating whether it is selected with initialData set, and reusing the wording already on the documented overload.

The implementation signature in each file is deliberately left undocumented — TypeDoc doesn't render it.

Prose was written against this adapter's own source rather than copied from React, since the reactive shapes differ.

Generated docs

pnpm run generate-docs updates exactly the 6 corresponding pages. The 10 deleted lines are Defined in: line-number shifts.

Summary by CodeRabbit

  • Documentation
    • Expanded Svelte API references with clearer explanations of query execution, infinite pagination, dynamic queries, fetching indicators, persisted client restoration, and custom query clients.

Remove the trailing * from both overload JSDoc blocks.

The literal * is rendered after the paging description in the generated reference page. Remove it from both descriptions.
