# 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): Omit<CreateQueryOptions<TQueryFnData, TError, TData, TQueryKey>, "queryFn"> & object & object;
```
