| ## `InfiniteQueryObserver` | |
| The `InfiniteQueryObserver` can be used to observe and switch between infinite queries. | |
| ```tsx | |
| const observer = new InfiniteQueryObserver(queryClient, { | |
| queryKey: ['posts'], | |
| queryFn: fetchPosts, | |
| getNextPageParam: (lastPage, allPages) => lastPage.nextCursor, | |
| getPreviousPageParam: (firstPage, allPages) => firstPage.prevCursor, | |
| }) | |
| const unsubscribe = observer.subscribe((result) => { | |
| console.log(result) | |
| unsubscribe() | |
| }) | |
| ``` | |
| **Options** | |
| The options for the `InfiniteQueryObserver` are exactly the same as those of [`useInfiniteQuery`](../../framework/react/reference/useInfiniteQuery). | |
