function provideQueryClient(queryClient): Provider;

Defined in: packages/angular-query-experimental/src/providers.ts:22

Usually provideTanStackQuery is used once to set up TanStack Query and the QueryClient for the entire application — it calls provideQueryClient internally. Use provideQueryClient directly to provide a different QueryClient instance for part of the application, or for unit testing.

Parameters

queryClient

A QueryClient instance, or an InjectionToken which provides a QueryClient.

QueryClient | InjectionToken<QueryClient>

Returns

Provider

A provider object that can be used to provide the QueryClient instance.

Example

Providing a test-only QueryClient in a component test, without wiring up provideTanStackQuery's other defaults:

TestBed.configureTestingModule({
  providers: [provideQueryClient(new QueryClient())],
})
