  queryFn: () => Promise.resolve(5),
  //  ^?  Promise<number>
})

const queryClient = new QueryClient()
const data = queryClient.getQueryData(queryKey)
//    ^?  number | undefined
```

## Param

The query options to tag with the type from `queryFn`.

## Call Signature

```ts
function queryOptions<TQueryFnData, TError, TData, TQueryKey>(
  options,
): DefinedInitialDataOptions<TQueryFnData, TError, TData, TQueryKey> & object
```
