feat(vue-query): return a reactive state from useQuery so status=== 'success' narrows data without unwrapping refs - #12541
I have tested code changes locally with pnpm run test:pr, or these tests do not apply to this pull request.
I have followed the AI contribution policy and fully understand the code in this pull request, including any code generated with AI assistance.
🚀 Release Impact
This change affects published code, and I have generated a changeset.
This change is docs/CI/dev-only (no release).
Summary by CodeRabbit
New Features
Vue query results now include a readonly reactive state object with plain-value fields. Checking its status narrows related fields, such as ensuring data is defined when the query succeeds. Existing query actions remain available on the composable result.
Documentation
Updated the Vue TypeScript guide and useQuery examples to demonstrate status-based narrowing and handling pending, error, and success states. The guide also explains how destructuring affects narrowing and how wrapping the result in reactive() can restore it.
useBaseQuery now exposes a readonly reactive state object with plain-value fields. Status checks narrow its fields. Tests and Vue documentation cover the state shape and its use.
Changes: Vue Query state
Layer / File(s)
Summary
Define and expose state packages/vue-query/src/useBaseQuery.ts
The return type adds a readonly distributive state union. The returned object exposes the state, and its refetch wrapper calls the observer directly and is restored after state updates.
Verify state shape and narrowing packages/vue-query/src/__tests__/useQuery.test.ts, packages/vue-query/src/__tests__/useQuery.test-d.ts
Runtime tests check the readonly, non-ref state, its updates, function-valued selected data, and refetch with reactive query keys. Type tests check status-based narrowing, state fields, initialData, and selected function types.
Document state usage packages/vue-query/src/useQuery.ts, docs/framework/vue/typescript.md, .changeset/vue-query-use-query-state.md
The useQuery example and Vue TypeScript guide describe state access and narrowing. The changeset records the patch.
The new state result works for the common cases. Two narrow edge cases remain: a select that returns a ref, and a synchronous watcher reading state mid-update. Neither is likely to affect most users, so this is mergeable with owner awareness.

Check that state.data changes after refetch.
Return different data from the second query call and assert the new value after refetch. The current assertion passes even if state.data retains the first result.

- Around line 189-193: The function-value filter in the useBaseQuery state loop
can delete function-valued data such as state.data when select returns a
function. Restrict removal to the query action keys refetch, fetchNextPage, and
fetchPreviousPage, while retaining the function type check; add a regression
test confirming function-valued initial data remains accessible after success.

Keep state.refetch() synchronized with reactive options.
When a reactive queryKey changes, a caller can invoke state.refetch() before the options watcher runs. state.refetch() then calls QueryObserver.refetch() without updater() and can fetch the previous query. Make state.refetch() use the same updater-before-refetch path as the top-level refetch() wrapper.

Update the `state.refetch()` implementation so it runs `updater()` before
delegating to `QueryObserver.refetch()`, matching the existing top-level
`refetch()` wrapper and ensuring the latest reactive options are used.

- Line 32: Update ReadonlyQueryState so its data type matches Vue’s behavior for
ref-valued select results: represent the unwrapped value in the default
deep-reactivity mode and preserve the Ref in shallow mode, or adjust runtime
behavior to make the existing type accurate in both modes. Add a regression test
covering ref-valued select data in both modes, including the observable
state.data value.
