🎯 Changes

Implements #9135

  • adds query and infiniteQuery methods as replacements for fetchQuery/fetchInfiniteQuery
  • new methods respect select, enabled and queryFn === skipToken
  • throws errors if enabled === false or queryFn === skipToken and no cached data is able to be returned.
  • updates tests for QueryClient
    • existing scenarios for fetchQuery fetch tests plus the new scenarios introduced (enabled, select, skipToken, static staleTime)
  • adds test for the queryOptions adaptor for react-query
  • added new methods to vue-query QueryClient subclass.

TODO when this is merged (I have stacked branches for these)

  • add new docs
  • refactor all the other tests to use the new methods (can be split up by package)
  • add deprecation tags to old methods (fetchQuery, prefetchQuery, ensureQueryData)

✅ Checklist

  • I have followed the steps in the Contributing guide.
  • I have tested this code locally with pnpm run test:pr.

🚀 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

📝 Walkthrough

Walkthrough

This PR adds new imperative query execution methods (query() and infiniteQuery()) to QueryClient alongside corresponding TypeScript option types, extends test coverage for static staleTime behavior, and renames FetchInfiniteQueryPages to InfiniteQueryPages for API consistency.

Changes

Cohort / File(s) Summary
Type Definitions
packages/query-core/src/types.ts
Added QueryExecuteOptions and InfiniteQueryExecuteOptions public types with support for enabled, select, and staleTime. Renamed FetchInfiniteQueryPages to InfiniteQueryPages and updated FetchInfiniteQueryOptions to reference the new type.
Query Core Implementation
packages/query-core/src/queryClient.ts
Added new public methods query() and infiniteQuery() to QueryClient with full generic type support, option handling, and delegation to existing internal cache flows.
Query Core Tests
packages/query-core/src/__tests__/queryClient.test-d.tsx, packages/query-core/src/__tests__/queryClient.test.tsx
Added comprehensive type tests for new QueryExecuteOptions and InfiniteQueryExecuteOptions types; added extensive runtime tests for static staleTime behavior, enabled/disabled states, select transformations, and meta propagation across query and infiniteQuery paths. Exposed noop() utility in public API.
Vue Integration
packages/vue-query/src/queryClient.ts
Added overloads for query() and infiniteQuery() methods supporting both direct options and MaybeRefDeep-wrapped options, delegating to parent class implementations with deep unref.
React Type Tests
packages/react-query/src/__tests__/queryOptions.test-d.tsx, packages/react-query/src/__tests__/infiniteQueryOptions.test-d.tsx
Added type tests validating select behavior with QueryClient().query(), infiniteQuery(), and confirming select is ignored for fetchQuery/fetchInfiniteQuery methods.
Changelog
.changeset/famous-owls-battle.md
Version bump documentation noting renamed imperative methods across @tanstack/react-query, @tanstack/query-core, and @tanstack/vue-query packages.

renames fetchQuery and fetchInfiniteQuery to query and infiniteQuery

sorry the idea was not to rename those, but to add new methods and deprecate the old ones. Otherwise, this would be a breaking change.

File: packages/solid-query-devtools/src/production.tsx:2-3
Timestamp: 2025-08-19T03:18:18.303Z
Learning: In the solid-query-devtools package, the codebase uses a pattern of type-only default imports combined with typeof for component type annotations (e.g., `import type SolidQueryDevtoolsComp from './devtools'` followed by `typeof SolidQueryDevtoolsComp`). This pattern is consistently used across index.tsx and production.tsx files, and the maintainers prefer consistency over changing this approach.

🔇 Additional comments (8)
packages/query-core/src/queryClient.ts (5)

140-159: LGTM! ensureQueryData correctly delegates to the new query method.

The internal delegation to query with staleTime: 'static' maintains the expected behavior while utilizing the new method.


336-365: Verify alignment with maintainer expectations regarding API migration strategy.

Per TkDodo's comment, the original intent was to "add new methods and deprecate the old ones to avoid a breaking change, not to remove/rename them outright." While this implementation maintains backward compatibility by keeping fetchQuery as a wrapper, please confirm that making query the primary implementation (rather than keeping fetchQuery as primary and adding query as an alias) aligns with the team's migration strategy.


384-393: LGTM! prefetchQuery correctly delegates to the new query method.

The delegation pattern with .then(noop).catch(noop) properly maintains the fire-and-forget prefetch behavior.


395-417: LGTM! infiniteQuery implementation is clean and consistent.

The method correctly sets the infiniteQueryBehavior and delegates to the query method. The type assertion on line 416 is necessary due to the behavior transformation.


436-452: LGTM! prefetchInfiniteQuery correctly delegates to the new infiniteQuery method.

The delegation pattern maintains the fire-and-forget prefetch behavior.

packages/query-core/src/__tests__/queryClient.test-d.tsx (1)

313-328: LGTM! Type assertions for new methods are comprehensive and correct.

The type checks for query and infiniteQuery methods properly cover both fully typed and untyped scenarios, maintaining consistency with the existing test structure.

Also applies to: 462-477

packages/query-core/src/__tests__/queryClient.test.tsx (1)

11-11: LGTM! Comprehensive test coverage for the new query methods.

The test additions are excellent:

  • Properly imports noop utility for prefetch patterns
  • Marks old test suites with @deprecated comments for clarity
  • Provides thorough coverage of new query and infiniteQuery methods including:
    • Static staleTime behavior
    • Prefetching scenarios
    • Type safety validation
    • Edge cases (cache hits, invalidation, GC, etc.)
  • Maintains parallel structure with legacy tests while validating new functionality

packages/vue-query/src/queryClient.ts (1)

256-346: LGTM! Vue Query extensions for new methods are well-implemented.

The query and infiniteQuery methods properly:

  • Provide overloads for both plain and MaybeRefDeep options
  • Use cloneDeepUnref to handle Vue's reactive refs correctly
  • Delegate to the parent QueryClient implementation
  • Follow the established pattern used by other methods in this class

DogPawHat commented Nov 1, 2025

From #9135:

Per default, this should behave like queryClient.fetchQuery does today:

  • it respects staleTime (like any good query should)
  • it returns a Promise you can await.

fetchQuery is still there, it's just a straight passthough for query now

161-172: LGTM!

The test correctly verifies that fetchQuery does not accept the select option, maintaining backward compatibility as intended in the PR design.


174-227: LGTM!

The tests correctly verify:

  • select option is not allowed on fetchInfiniteQuery (backward compatibility)
  • pages parameter is properly typed
  • getNextPageParam is required when pages is specified

229-239: LGTM!

The test correctly verifies that the new query method accepts the select option, which is the key differentiator from the fetchQuery compatibility wrapper.


242-257: Verify whether select should be allowed on infiniteQuery.

This test asserts that select is not allowed on infiniteQuery, but:

  1. Lines 336-339 show InfiniteQueryExecuteOptions being used with a select option successfully
  2. Unlike the fetchInfiniteQuery test (line 183), there's no @ts-expect-error annotation on the select property (line 249)

Based on the implementation where infiniteQuery delegates to query (which supports select), it appears select should be allowed. Please clarify the intended behavior and add the @ts-expect-error annotation if select is truly not supported, or update the test description if it is supported.


428-429: LGTM!

The type check correctly verifies that query returns the expected TData type.


578-579: LGTM!

The type check correctly verifies that query returns unknown when called with untyped options.


583-593: LGTM!

The type checks correctly verify the return types for fetchInfiniteQuery and infiniteQuery with untyped options, both returning InfiniteData<unknown, unknown>.

13-13: LGTM!

The addition of InfiniteQueryExecuteOptions to the imports aligns with the new public API surface introduced in this PR.


161-172: LGTM!

This test correctly validates that the legacy fetchQuery method does not support the select option, with proper use of @ts-expect-error to enforce the type constraint.


174-227: LGTM!

The tests for fetchInfiniteQuery correctly validate the legacy behavior, including:

  • Properly rejecting select option with @ts-expect-error
  • Validating the pages option with correct type expectations
  • Enforcing required parameter constraints

229-239: LGTM!

This test correctly validates that the new query method supports the select option for data transformation, properly demonstrating the enhanced functionality compared to the legacy fetchQuery.


328-336: LGTM!

The integration of the new query and infiniteQuery methods into the fully-typed and untyped test sections is correct:

  • Proper usage of InfiniteQueryExecuteOptions<TData, TError> type
  • Correct type expectations for return values
  • Good coverage of both typed and untyped variants

491-509: LGTM: QueryExecuteOptions introduces select support correctly.

The new QueryExecuteOptions interface properly introduces the select transformation flow via the TQueryData generic. The data flows as TQueryFnData (raw) → TQueryData (intermediate) → TData (final via select). The staleTime correctly uses TQueryData since staleness should be determined from the query's stored data, not the transformed result.


511-528: LGTM: FetchQueryOptions maintains backward compatibility.

The refactor to make FetchQueryOptions an alias that omits select from QueryExecuteOptions is correct. Passing TData as both the 3rd and 4th generics (TData, TData) ensures no transformation layer exists when select is omitted, maintaining the original behavior of fetchQuery.


568-586: LGTM: InfiniteQueryExecuteOptions properly extends execute options.

The type correctly:

  • Omits initialPageParam from QueryExecuteOptions (which has initialPageParam?: never)
  • Re-adds it via InitialPageParam<TPageParam> with the proper type
  • Uses InfiniteData<TQueryFnData, TPageParam> as the intermediate data shape
  • Includes InfiniteQueryPages discriminated union to enforce the pages/getNextPageParam constraint
packages/query-core/src/__tests__/queryClient.test-d.tsx (4)

161-172: LGTM: Correctly verifies fetchQuery rejects select.

The test properly uses @ts-expect-error to confirm that the legacy fetchQuery method does not support the select option, maintaining backward compatibility.

Based on learnings.


229-239: LGTM: Correctly verifies query accepts select.

The test confirms that the new query method supports the select option for data transformation, using assertType (without @ts-expect-error) to validate this is allowed.

Based on learnings.


241-257: LGTM: Correctly verifies infiniteQuery accepts select.

The test confirms that the new infiniteQuery method supports the select option for transforming infinite query data, using assertType (without @ts-expect-error) to validate this is allowed.

Based on learnings.


328-336: LGTM: infiniteQueryOptions properly typed.

The variable correctly uses InfiniteQueryExecuteOptions<TData, TError> with defaults for remaining generics. The getNextPageParam callback properly receives lastPage typed as TData.

428-450: Implementation delegates correctly, but consider type-safe alternatives to the cast.

The method properly sets infiniteQueryBehavior before delegating to query. The as any cast on line 449 bypasses type safety—consider whether tighter generic constraints or a helper could eliminate it.

491-509: LGTM! Well-designed interface for query execution options.

The interface correctly separates TQueryData from TData to enable optional select transformation, explicitly prevents initialPageParam for single queries, and provides clear documentation for staleTime behavior.


561-586: LGTM! Clean type composition for infinite query execution.

The discriminated union for InfiniteQueryPages and the composition strategy for InfiniteQueryExecuteOptions (omitting the never field then adding the required version) correctly enforces that infinite queries must provide initialPageParam.

packages/query-core/src/queryClient.ts (2)

343-384: LGTM! Core query execution logic is sound.

The method correctly handles stale-time checking, optional data fetching, and select transformation. The double cast as unknown as TData on line 383 is a TypeScript workaround when no select is provided (TData defaults to TQueryData), though it's safe in practice.


452-468: Fix: Missing options.behavior setup before delegation to fetchQuery.

The fetchInfiniteQuery method must set options.behavior before delegating to fetchQuery, matching the pattern used in infiniteQuery (lines 443-448) and ensureInfiniteQueryData (lines 503-508). Without this, infinite query pagination will not work correctly.

 fetchInfiniteQuery<
   TQueryFnData,
   TError = DefaultError,
   TData = TQueryFnData,
   TQueryKey extends QueryKey = QueryKey,
   TPageParam = unknown,

428-450: Fix the type error and avoid as any assertion.

Two issues need to be addressed:

  1. Pipeline failure (Line 443): The type error indicates that QueryBehavior<TQueryFnData, TError, InfiniteData<TQueryFnData, TPageParam>, readonly unknown[]> is not assignable to QueryBehavior<TQueryFnData, TError, InfiniteData<TQueryFnData, TPageParam>, TQueryKey>. This suggests a mismatch in the query key type constraint.

  2. Line 449: The as any type assertion bypasses type safety and hides potential type errors. This indicates that the types don't align properly between InfiniteQueryExecuteOptions and QueryExecuteOptions.

The type system should properly model the relationship between these option types without requiring unsafe casts. Please investigate:

  • Whether the QueryExecuteOptions type needs to be adjusted to properly accept infinite query options
  • Whether the generic constraints need to be refined to make the types compatible
  • Alternative approaches that maintain type safety

28-28: LGTM!

The new type imports support the query and infiniteQuery method signatures correctly.

Also applies to: 37-37


373-383: Verify data handling assumptions in the query method implementation.

The technical concerns in the review are valid: when isStale is false, query.state.data could be undefined (initialized without initialData), and this would be passed to the select function without a guard. The type signature select?: (data: TQueryData) => TData expects defined data, but the cast on line 375 (as TQueryData) doesn't guarantee it at runtime.

However, test cases across the codebase show select always receives properly typed, defined data—no scenario in tests passes undefined to the selector. This suggests either:

  1. The scenario is prevented by caller contracts (e.g., always providing initialData or ensuring fetch completes first)
  2. The stale-time logic prevents isStale=false when data is undefined
  3. This is an edge case not covered by tests

Confirm whether adding a guard (e.g., if (!queryData) return queryData as TData) is necessary, or if the current design intentionally relies on caller responsibility to provide valid initial state.

428-452: Restore infiniteQueryBehavior wiring for fetchInfiniteQuery and reduce as any surface

Currently, only infiniteQuery and ensureInfiniteQueryData attach infiniteQueryBehavior, while fetchInfiniteQuery now delegates straight to fetchQuery without setting options.behavior:

fetchInfiniteQuery(...) {
  return this.fetchQuery(options as any)
}

In the published build, fetchInfiniteQuery sets options.behavior = infiniteQueryBehavior(options.pages) before calling fetchQuery, which is what gives it proper infinite paging semantics (using pages, pageParams, and getNextPageParam). (impactic.de) Dropping that here likely breaks existing fetchInfiniteQuery behavior and will make tests like “should return infinite query data”/“should prefetch multiple pages” incorrect at runtime.

I’d strongly suggest restoring the behavior setup, e.g.:

  fetchInfiniteQuery<
    TQueryFnData,
    TError = DefaultError,
    TData = TQueryFnData,
    TQueryKey extends QueryKey = QueryKey,
    TPageParam = unknown,
  >(
    options: FetchInfiniteQueryOptions<
      TQueryFnData,
      TError,
      TData,
      TQueryKey,
      TPageParam
    >,
  ): Promise<InfiniteData<TData, TPageParam>> {
    options.behavior = infiniteQueryBehavior<
      TQueryFnData,
      TError,
      TData,
      TPageParam
    >(options.pages)
    return this.fetchQuery(options as any)
  }

On top of that, the three as any casts (this.query(options as any), this.fetchQuery(options as any), this.ensureQueryData(options as any)) are understandable given the generic differences between execute/fetch option types, but they do punch a hole through type safety. If feasible, consider a small internal helper or tightening the generic relationships between QueryExecuteOptions, InfiniteQueryExecuteOptions, FetchQueryOptions, and FetchInfiniteQueryOptions so these calls can be expressed without any (or at least with a narrower cast and a brief comment on why it’s safe).

53-66: Type tests correctly encode select behavior for infinite paths

The new tests nicely capture the intended distinctions:

  • useInfiniteQuery, useSuspenseInfiniteQuery, and QueryClient.infiniteQuery all see select and return the transformed Array<string> type.
  • fetchInfiniteQuery still yields InfiniteData<string, number> even when given options that include select, matching the legacy “no select” behavior for fetch APIs.

Only tiny nit: the “known issue” comment in the suspense test still mentions useInfiniteQuery, but that’s cosmetic.

packages/query-core/src/types.ts (1)

491-509: New execute option types align well with observer options and infinite semantics

QueryExecuteOptions and InfiniteQueryExecuteOptions are wired correctly: using TQueryData for staleTime and select matches how defaultQueryOptions and resolveStaleTime operate, and InfiniteQueryPages cleanly enforces the pages/getNextPageParam pairing while being reused by both execute and fetch infinite options. This should give query/infiniteQuery the right type-level behavior without impacting existing Fetch* callers.

Also applies to: 561-587, 588-605

packages/react-query/src/__tests__/queryOptions.test-d.tsx (1)

58-66: query vs fetchQuery select behavior is well covered

The added tests clearly distinguish the new query API (including select transformations) from the legacy fetchQuery (which returns the raw number even when given options that contain select). This matches the intended separation between the new and old imperative entry points.

Also applies to: 76-95

packages/query-core/src/__tests__/queryClient.test-d.tsx (2)

161-172: Type tests cleanly separate select support between legacy and new APIs

The new blocks for fetchQuery, fetchInfiniteQuery, query, and infiniteQuery correctly encode the contract:

  • fetchQuery/fetchInfiniteQuery reject select at the option level via @ts-expect-error.
  • query/infiniteQuery accept select and assert the transformed data types.

This gives solid type-level coverage for the migration story from the old fetch* APIs to the new imperative methods.

Also applies to: 175-192, 229-257


193-203: Infinite execute/fetch options generics are exercised thoroughly

The updated tests around passing pages, using { count: number } pages, and the “fully typed usage” blocks validate that:

  • FetchInfiniteQueryOptions and InfiniteQueryExecuteOptions expose lastPage as TData in getNextPageParam.
  • infiniteQuery and fetchInfiniteQuery both resolve to InfiniteData<TData, TPageParam> (or InfiniteData<unknown, unknown> in the untyped case).

This gives good confidence that the new infinite-execute types integrate correctly with QueryClient’s generics.

Also applies to: 259-269, 328-337, 422-435, 569-585

packages/query-core/src/__tests__/queryClient.test.tsx (2)

529-620: Static staleTime behavior for query/infiniteQuery is well specified

The new “with static staleTime” suites for both query and infiniteQuery clearly pin down the behavior:

  • Cached data (including falsy values) is returned without re-fetching when staleTime is 'static'.
  • Missing queries invoke queryFn once.
  • Providing initialData short-circuits network calls.
  • A second call with staleTime: 0 drives an explicit background revalidation, as verified via noop and cache assertions.

This is a strong regression suite for the new imperative surface.

Also applies to: 683-720


928-1106: Runtime tests give good confidence in new query/infiniteQuery entry points

The added query/infiniteQuery suites (including “used for prefetching”) thoroughly mirror the legacy fetchQuery/prefetch* behavior:

  • No-retry-by-default semantics, gcTime handling, and static staleTime cache hits are preserved.
  • Infinite flows still produce the expected InfiniteData shapes, including multi-page prefetch and early termination via getNextPageParam.
  • Prefetch-style usages (.catch(noop)) ensure that using query/infiniteQuery purely for seeding the cache continues to work.

Overall, the tests look well aligned with the intended migration path from the deprecated fetch* methods to the new APIs.

Also applies to: 1153-1195, 1287-1380, 1432-1483

packages/vue-query/src/queryClient.ts (1)

19-37: Vue QueryClient query/infiniteQuery wrappers are consistent and type-safe

The new query and infiniteQuery overloads:

  • Reuse the core QueryExecuteOptions / InfiniteQueryExecuteOptions generics correctly.
  • Preserve the Vue adapter’s MaybeRefDeep + cloneDeepUnref pattern so refs and getter-based queryKeys are handled before delegating.
  • Return the expected Promise<TData> / Promise<InfiniteData<TData, TPageParam>> types, matching the core client.

This keeps the Vue surface in lockstep with the new imperative APIs.

Also applies to: 258-366

packages/query-core/src/queryClient.ts (1)

343-384: query implementation correctly layers select on top of legacy fetch semantics

The new query method:

  • Runs through defaultQueryOptions, preserves the “no retry by default” behavior from fetchQuery, and uses resolveStaleTime with QueryExecuteOptions.staleTime typed on TQueryData.
  • Fetches when isStaleByTime is true, otherwise returns query.state.data from cache.
  • Applies select once, purely at the imperative layer, without mutating the stored query data.

This matches the intended contract for the new imperative API and is well covered by the added runtime and type tests.

428-454: Type assertion bypasses type safety.

Line 453 uses as any when delegating to this.query, which bypasses TypeScript's type checking. While this mirrors the existing pattern in fetchInfiniteQuery (Line 477), the cast suggests that InfiniteQueryExecuteOptions and QueryExecuteOptions aren't properly aligned.

Consider refactoring to eliminate the cast by:

  • Ensuring type compatibility between the two option types
  • Extracting a shared internal helper that both methods can call with appropriate generic bounds

343-384: LGTM! The query method logic is sound.

The implementation correctly:

  • Defaults retry to false (matching fetchQuery behavior)
  • Checks staleness via resolveStaleTime
  • Fetches when stale or returns cached data
  • Applies select transformation when provided

The double cast at Line 383 (as unknown as TData) is safe given that TData defaults to TQueryData when select is not provided, though it's overly defensive.

Based on learnings, the new query method correctly supports the select option for data transformation.

packages/query-core/src/types.ts (1)

491-509: LGTM! Type definitions are well-structured.

The new type definitions are correctly designed:

  • QueryExecuteOptions (491-509): Properly extends QueryOptions with required queryKey, adds select for data transformation, and includes staleTime for staleness control
  • InfiniteQueryPages (561-566): Clean discriminated union that allows optional pages specification or requires getNextPageParam when pages are specified
  • InfiniteQueryExecuteOptions (568-586): Well-composed type combining QueryExecuteOptions, InitialPageParam, and InfiniteQueryPages
  • FetchInfiniteQueryOptions (605): Updated to reuse InfiniteQueryPages, improving consistency

Based on learnings, the new types correctly support the select option for data transformation in query and infiniteQuery methods.

Also applies to: 561-586, 605-605

48-54: ⚠️ Potential issue | 🟡 Minor

CDN example pins a significantly outdated React version.

react@18.2.0 was released in June 2022. The latest React 18 release is 18.3.1 (April 2024), and React 19 (currently 19.2.x) is the current stable major. The pinned version is over three years old and misses all React 18 security/patch releases.

At minimum, update the pin to 18.3.1; consider bumping to React 19 given the compatibility note already says "v18+" (which may itself need updating to explicitly include v19).

In `@packages/query-core/src/__tests__/queryClient.test-d.tsx`:
- Around line 206-227: The test title is misleading: the case using
getNextPageParam without pages is asserted to be allowed (no `@ts-expect-error`),
so rename the test description from "should not allow passing getNextPageParam
without pages" to something like "should allow passing getNextPageParam without
pages" to match the assertion in the block that calls assertType with
Parameters<QueryClient['fetchInfiniteQuery']> and the options containing
getNextPageParam, queryFn, initialPageParam, and queryKey.

In `@packages/query-core/src/queryClient.ts`:
- Around line 448-474: The infiniteQuery method currently bypasses type safety
by casting options to any before calling query; update the code so the options
type matches what query expects instead of using `as any`: either produce a
correctly typed options object (e.g., compute a new const typed as the
appropriate QueryExecuteOptions/QueryOptions type) or create a small typed
internal helper/overload that accepts InfiniteQueryExecuteOptions and maps to
the exact parameter type of query; adjust the generics on
infiniteQueryBehavior/infiniteQuery so the resulting options type aligns with
query's signature (references: infiniteQuery, infiniteQueryBehavior, query) and
run the TypeScript typecheck to confirm no unsafe casts remain.
