| title: QueryObserver | |
| The `QueryObserver` can be used to observe and switch between queries. | |
| ```tsx | |
| const observer = new QueryObserver(queryClient, { queryKey: ['posts'] }) | |
| const unsubscribe = observer.subscribe((result) => { | |
| console.log(result) | |
| unsubscribe() | |
| }) | |
| ``` | |
| **Options** | |
| The options for the `QueryObserver` are exactly the same as those of [`useQuery`](../../framework/react/reference/useQuery). | |
