## `QueriesObserver`
The `QueriesObserver` can be used to observe multiple queries.
```tsx
const observer = new QueriesObserver(queryClient, [
{ queryKey: ['post', 1], queryFn: fetchPost },
{ queryKey: ['post', 2], queryFn: fetchPost },
])
const unsubscribe = observer.subscribe((result) => {
console.log(result)
unsubscribe()
})
```
**Options**
The options for the `QueriesObserver` are exactly the same as those of [`useQueries`](../framework/react/reference/useQueries).
