How to decorate current state resolve function in UI-Router? Current function isn't invoked

Question

I\'m trying to DRY in $stateProvider and prevent adding the same auth function in each resolve. I\'ve created decorator that in each state change w

Answer 1

I realized that $delegate.current object contains only raw stateProvider config data. To wrap resolve function I add my function to $delegate.$current on each state change.

$provide.decorator('$state', function($delegate, $rootScope) {
  $rootScope.$on('$stateChangeStart', function(event, state, params) {
    if ($delegate.current === "err404" || $delegate.current === "login" || $delegate.current === "register") {
      return;
    }
    console.log("decorator", $delegate);
    $delegate.$current.resolve["auth"] = ['AuthService', '$stateParams', function(AuthService, $stateParams) {
      if (AuthService.isAuthenticated()) {
        console.log('AuthService.me()');
        return AuthService.me();
      } else {
        return false;
      }
    }]
  });
  return $delegate;
});

Update

I found related discussion on github, you can add universal resolve function into toState param:

app.run(['$rootScope', '$state',
  function($rootScope, $state) {

    $rootScope.$on('$stateChangeStart', function(event, toState) {

      if (toState.name === "login" || toState.name === "register") {
        return;
      }

      toState["resolve"]["auth"] = ['AuthService', '$stateParams', function(AuthService, $stateParams) {
        if (AuthService.isAuthenticated()) {
          return AuthService.me();
        } else {
          return false;
        }
      }];
    });
  }
]);
