Summary

  • useQuery's @returns described pending as "no cached data and no query attempt has finished yet." That's inaccurate: fetchState (query-core) resets status to pending whenever there's no cached data, even after a prior attempt ended in error.
  • error is also unconditional on data presence — a failed background refetch sets status: 'error' even while cached data still exists.
  • Corrected to: "status is pending if there is no cached data to display, error if the last fetch attempt failed, or success if the query has data to display."
  • Regenerated docs/framework/preact/reference/functions/useQuery.md to match.

Found while porting this same @returns sentence to svelte-query (#11352) and verifying it against query.ts's fetchState/case 'error'/case 'success' reducers.

Summary by CodeRabbit

  • Documentation
    • Clarified useQuery status descriptions.
    • Updated guidance to explain that pending applies when no cached data is available and error indicates the latest fetch attempt failed.

Review Change Stack

📝 Walkthrough

Walkthrough

The useQuery return documentation now defines pending as having no cached data to display and error as a failed last fetch attempt. The wording is synchronized across both overloads in the source and Preact reference documentation.

Changes

useQuery status documentation

Layer / File(s) Summary
Update useQuery status descriptions
packages/preact-query/src/useQuery.ts, docs/framework/preact/reference/functions/useQuery.md
Both useQuery overloads use the revised pending and error status descriptions. Derived boolean descriptions remain unchanged.

Estimated code review effort: 1 (Trivial) | ~2 minutes

Merge Risk: 🔵 Low · up to efa50

The PR updates useQuery status documentation in both source and generated docs, but the expected definitions of pending and error remain disputed; merging without resolving that contract question could leave users with incorrect guidance.

Align useQuery status documentation with QueryStatus. Use the definitions from packages/query-core/src/types.ts: pending means no cached data and no finished query attempt; error means the query attempt resulted in an error; success means a response was received without errors and is ready to display. Apply this to both source overloads and regenerate both documented overloads.
