How to use the @dbeining/react-atom.Atom function in @dbeining/react-atom

function getAppManifestAtom(appUri) {
  // Out: Atom promise containing a either an app manifest or a null value.
  // Avoid passing outside this module to avoid conflicts if there are multiple react-atom packages in the project
  var atom = _reactAtom.Atom.of(null);

  var setValue = function setValue(value) {
    return (0, _reactAtom.swap)(atom, function (state) {
      return value;
    });
  };

  try {
    var manifestUri = appUri + "/manifest.json";
    var controller = new AbortController();

    var cleanup = function cleanup() {
      return controller.abort();
    };

    console.info("FETCHING:", manifestUri);
