# QueryCache

Defined in: [vue-query/src/queryCache.ts:16](https://github.com/TanStack/query/blob/main/packages/vue-query/src/queryCache.ts#L16)

Vue-aware subclass of `@tanstack/query-core`'s `QueryCache`. `find`/`findAll` also accept a
MaybeRefDeep filters object, so `ref`s can be passed directly without unwrapping. Access it via
`queryClient.getQueryCache()` — `QueryClient` constructs one of these by default.
