export const App = () => {
  const [projects, loading, error] = useQuery(getProjects(), (project) => ({
    ownerRef: {
      nowPlayingRef: {},
    },
    kanbans: field(getKanbans(project.ref), (kanban) => ({
      todoLists: field(getTodoLists(kanban.ref), {}),
    })),
  }));

  return (
    <div>
        {projects.map(project => (
            <div key={project.id}>
                <p>{project.data.owner.data?.name}</p>
                <p>{project.data.owner.data?.nowPlaying.data?.title}</p>
                <p>{project.data.kanbans.length}</p>
            </div>
        ))}
    </div>
  );
};
