QueryObserver
The QueryObserver can be used to observe and switch between queries.
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.
