Using createResource conditionally

// data fetcher
function fetchData() {
  const [data] = createResource(fetcher);
  return data;
}

// "derived" signal
const data = () => {
  // "isLoggedIn" is a signal, so I want "data"
  // to reactively resolve to false if user logs out
  // and resolve to createResource signal if logs in 
  if (!User.isLoggedIn()) return false;
  return fetchData();
}

// test it out 
createEffect(() => {
  console.log('output:', data());
});

output: ƒ read() {
    const c = SuspenseContext && lookup(Owner, SuspenseContext.id),
          v = value(),
          err = error();
    if (err && !pr) throw err;
    if (Listener && !Listener.user && c) {
