How to redirect in a ui-router resolver?

Question

I am trying to redirect inside a ui-router resolve and wanted to know if there is a way to reroute in a router resolver. Currently this does not work as one would think.

Answer 1

You can return a promise from your resolver function that will indicate whether to continue navigating to the state or not. If you decide to navigate somewhere else - reject the promise and specify the proper state:

resolver($q, $state, $timeout, auth) {
    var deferred = $q.defer();

    // $timeout is an example; it also can be an xhr request or any other async function
    $timeout(function() {
      if (!auth.isLoggedIn()) {
        // user is not logged, do not proceed
        // instead, go to a different page
        $state.go('noLoggedInPath');
        deferred.reject();
      } else {
        // everything is fine, proceed
        deferred.resolve();
      }
    });

    return deferred.promise;
}

Plunkr here.

UPD: updated code and added plunkr. Looks like it only works if you put it inside a timeout function.
