MutationCacheConfig

Defined in: packages/query-core/src/mutationCache.ts:26

Global callbacks that fire for every mutation handled by a MutationCache, regardless of which component or observer triggered it. They differ from the defaultOptions provided to a QueryClient in two ways: defaultOptions can be overridden by each mutation, while these callbacks are always called, and onMutate here does not allow returning a result.

If a callback returns a promise, it will be awaited before the mutation continues.
