feat(query): add useSkipToken option to hold unresolved params by oliverwinter-vdb · Pull Request #3994 · orval-labs/orval

oliverwinter-vdb · 2026-09-04T13:00:30Z

Closes #3993.

enabled cannot carry "the param has not arrived yet":

it does not gate refetch(), so a retry button or pull-to-refresh sends GET /pets/undefined;
it is a single option and the caller's ...queryOptions is spread last, so useShowPetById(petId, { query: { enabled: isTabVisible } }) silently replaces the generated param check.

This adds an opt-in override.query.useSkipToken (default false) that holds the query in queryFn with TanStack's skipToken instead of emitting the enabled guard:

return {
  queryKey,
  queryFn: petId === null || petId === undefined ? skipToken : queryFn,
  ...queryOptions,
};

enabled then stays free for the caller, and refetch() cannot bypass the check.

Scope

React Query v5 only (adapter.hasQueryV5) — skipToken does not exist before v5. The other v5 adapters (solid/svelte/vue) each have their own generateEnabledOption; I don't work in those frameworks enough to be confident about the equivalent, so they are left alone.
Replaces the enabled guard wherever that guard is emitted.
Suspense queries are untouched: TanStack excludes SkipToken from their queryFn type, which is also why they get no enabled guard today.
Query keys are unchanged.

Behaviour change to be aware of

With the option on, refetch() before the params resolve puts the query into the error state (Missing queryFn) instead of firing a request with undefined in the URL. I think the error is the better outcome, but it is a visible difference for anyone enabling the option.

Verification

@orval/query unit tests: 193 pass, including new cases for getQueryFnProperty (multi-param, infinite, both suspense types) and generateQueryOptions (guard dropped, configured options kept, guard still emitted when off).
vp run test:snapshots: 7350 pass, and regenerating every sample leaves no diff — with the default off this is a no-op.
vp fmt --check, vp run typecheck and vp lint --type-aware --type-check packages are clean.
Generated samples/react-query/basic/petstore.yaml with useSkipToken: true + allParamsOptional: true: the showPetById factory emits the skipToken branch and no enabled guard, the suspense factory is unchanged, and a probe calling useShowPetById(petId, { query: { enabled: true } }) with petId?: string typechecks (tsc --noEmit). The scratch config and output were not committed.

Docs

docs/content/docs/guides/react-query.mdx gets a short "Skip Token" section (what it emits and the two cases enabled does not cover), and output.mdx gets the useSkipToken reference entry.

Summary by CodeRabbit

New Features
- Added optional TanStack Query v5 skipToken support for generated queries with unresolved parameters.
- Unresolved queries send no request; early refetch() rejects with a Missing queryFn error.
- Caller-provided query options remain supported.
- Support is limited to React Query v5; other adapters and React Query v4 retain existing behavior.
- Suspense queries remain unaffected.
Documentation
- Added guidance on configuration, behavior differences from enabled, parameter requirements, and usage recommendations.
Tests
- Added coverage for adapter compatibility and generated query options with and without skipToken.

…-labs#3993) `enabled` cannot carry "the param has not arrived". It is a single option and `...queryOptions` is spread last, so a caller passing its own `enabled` replaces the generated param check; and `enabled` does not gate `refetch()`, so a retry button sends the request with the unresolved param in the URL. With `useSkipToken`, the factory holds the query in `queryFn` instead, which leaves `enabled` free for the caller and makes `refetch()` refuse. Replaces the `enabled` guard wherever that guard is emitted, so it has no relation to `allParamsOptional`. Suspense queries are excluded: TanStack removes `SkipToken` from their `queryFn` type, which is also why they get no `enabled` guard. React Query v5 only; the query key is unchanged.

📝 Walkthrough

Walkthrough

Adds opt-in useSkipToken support for generated React Query v5 hooks. Unresolved parameters use skipToken instead of an enabled guard. The change updates option types, normalization, generation, tests, and documentation.

Changes

React Query skipToken support

Layer / File(s)	Summary
Option contract and dependency wiring `packages/core/src/types.ts`, `packages/core/src/test-utils/context.ts`, `packages/orval/src/utils/options.ts`, `packages/query/src/dependencies.ts`	Adds `useSkipToken` to query option types, default test configuration, normalized options, and React Query dependency exports.
skipToken query generation `packages/query/src/query-options.ts`, `packages/query/src/query-generator.ts`	Resolves the option for React Query v5, generates a `skipToken` query function for unresolved parameters, and omits the generated `enabled` guard.
Behavior validation and documentation `packages/query/src/query-generator.test.ts`, `packages/query/src/query-options.test.ts`, `docs/content/docs/guides/react-query.mdx`, `docs/content/docs/reference/configuration/output.mdx`	Tests query-function generation, adapter restrictions, suspense exclusions, and option output. Documents configuration and runtime differences from `enabled`.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: ⚪ Minimal · up to fa432

The opt-in React Query v5 skipToken behavior is documented to prevent unresolved-parameter requests while preserving the existing default behavior. No current merge-blocking risk is identified.

commit: fa43240

`hasQueryV5` is set by the vue, svelte, solid and angular adapters too, so `useSkipToken` reached them as well: they emitted `skipToken` without importing it — it lives in `@tanstack/react-query` — and dropped an `enabled` guard whose shape is framework-specific (vue unwraps refs in its check). Verified against `samples/vue-query/vue-query-basic`: before this, the vue factory emitted `queryFn: petId === null || petId === undefined ? skipToken : queryFn`. Resolve the flag through `resolveUseSkipToken`, so the client check sits with the version check that already gates it.

`skipToken` does not stop `refetch()` from running, it only stops the request: query-core's `ensureQueryFn` returns a rejecting function, so the query lands in error with `Missing queryFn` (and a console error in development). Saying it "blocks refetch()" hid the tradeoff the option asks callers to accept.
