How do you update a list after successfully creating an item via `useMutation`?

✓Correct answer: Call invalidateQueries for ['todos'] in onSuccess
2Reload the page via location.reload() in onSuccess
3Call useQuery again inside the onSuccess callback

Explanation

Invalidation marks queries as stale and refetches the active ones. The alternative is to update the cache directly via setQueryData if the server returned the new object. Hooks can't be called inside callbacks.
