--- id: query-options title: Query Options --- One of the best ways to share `queryKey` and `queryFn` between multiple places, yet keep them co-located to one another, is to use the `queryOptions` helper. At runtime, this helper just returns whatever you pass into it, but it has a lot of advantages when using it [with TypeScript](../../typescript.md#typing-query-options). You can define all possible options for a query in one place, and you'll also get type inference and type safety for all of them. [//]: # 'Example1' ```ts import { queryOptions } from '@tanstack/react-query' function groupOptions(id: number) { return queryOptions({ queryKey: ['groups', id], queryFn: () => fetchGroups(id), staleTime: 5 * 1000, }) } // usage: useQuery(groupOptions(1)) useSuspenseQuery(groupOptions(5)) useQueries({ queries: [groupOptions(1), groupOptions(2)], }) queryClient.prefetchQuery(groupOptions(23)) queryClient.setQueryData(groupOptions(42).queryKey, newGroups) ``` [//]: # 'Example1' For Infinite Queries, a separate [`infiniteQueryOptions`](../../reference/infiniteQueryOptions.md) helper is available. You can still override some options at the component level. A very common and useful pattern is to create per-component [`select`](../render-optimizations.md#select) functions: [//]: # 'Example2' ```ts // Type inference still works, so query.data will be the return type of select instead of queryFn const query = useQuery({ ...groupOptions(1), select: (data) => data.groupName, }) ``` [//]: # 'Example2'
