Add argument to useQuery to allow result to be filtered and sorted

[takameyer]

Problem

Currently when using useQuery, the result must be passed into a useMemo in order to get a memoized filtered or sorted result. This is also not particularly useful, as when the result of useQuery is re-rendered, the memo is called again as well as any filtered or sorted method calls.

For example

  const user = useUser();
  const userId = user.id;
  const result = useQuery(Task);

  const tasks = useMemo(() => result.filtered(“ownerId == $0”, userId).sorted('createdAt'), [result, userId]);

Solution

A more elegant solution would be to have a callback within useQuery which would allow the filtered and sorted functions to be applied within useQuery itself. It could also take a dependency array to determine when to reset the filtered or sorted method calls.

 const tasks = useQuery("Task", (tasks) => {
   return tasks.filtered(“ownerId == $0”, userId);
 }, [userId]);
