API Reference

QueryCacheConfig

Defined in: packages/query-core/src/queryCache.ts:25

Global callbacks that fire for every query handled by a QueryCache, regardless of which component or observer triggered it. Unlike QueryClient's defaultOptions, which a query can override, these callbacks are always called. Unlike MutationCacheConfig's callbacks, these are fire-and-forget: their return value is not awaited before the query settles.
