# QueryClient

Defined in: [vue-query/src/queryClient.ts:44](https://github.com/TanStack/query/blob/main/packages/vue-query/src/queryClient.ts#L44)

Vue-aware subclass of `@tanstack/query-core`'s `QueryClient`. Methods that accept `options` (such as
`CancelOptions` or `InvalidateOptions`) or filters (such as the `QueryFilters` accepted by
`invalidateQueries`) also accept a MaybeRefDeep version of it, so you can pass `ref`s directly
without unwrapping them yourself — e.g. `queryClient.invalidateQueries({ queryKey: ['post', myRef] })`.
Install one on your app with `VueQueryPlugin`, or retrieve it with `useQueryClient`.

## Extends

## Constructors

### Constructor

new QueryClient(config): QueryClient;
```

Defined in: [vue-query/src/queryClient.ts:45](https://github.com/TanStack/query/blob/main/packages/vue-query/src/queryClient.ts#L45)

#### Parameters

##### config

`QueryClientConfig` = `{}`

#### Returns

`QueryClient`

#### Overrides

```

Defined in: [vue-query/src/queryClient.ts:58](https://github.com/TanStack/query/blob/main/packages/vue-query/src/queryClient.ts#L58)

`true` while a `clientPersister` passed to `VueQueryPlugin` is restoring the cache. Queries don't fetch
while this is `true`. Defaults to `false` if no persister is configured.

Defined in: [vue-query/src/queryClient.ts:68](https://github.com/TanStack/query/blob/main/packages/vue-query/src/queryClient.ts#L68)

Imperative (non-reactive) way to retrieve data for a QueryKey.
Should only be used in callbacks or functions where reading the latest data is necessary, e.g. for optimistic updates.

Hint: Do not use this function inside a component, because it won't receive updates.
Use `useQuery` to create a `QueryObserver` that subscribes to changes.
