# Function: queryOptions()
Allows to share and re-use query options in a type-safe way.
The `queryKey` will be tagged with the type from `queryFn`.
**Example**
```ts
const { queryKey } = queryOptions({
queryKey: ['key'],
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
```
