Tips for guaranteeing synchronous loading in your angularjs app.js

Here's the code I'm working with:

    getTens.getToken($rootScope.webUserInfo[0].username).then(function(resulttoken) {
        $rootScope.userInfo = resulttoken;
        $sessionStorage.token = resulttoken[0].token;
        $sessionStorage.userInfoStorage = $rootScope.userInfo;
        CasesGroupByCaseStatus.getListing($rootScope.webUserInfo[0].username).then(function(data){
          $rootScope.listingDetails = data;
          $sessionStorage.listingDetailsStorage = $rootScope.listingDetails;
        });

        CasesGroupByCaseStatus.caseStatusCount($rootScope.webUserInfo[0].username).then(function(resultcaseStatus){
          $rootScope.dashboardStatus = resultcaseStatus;
          $sessionStorage.dashboardStatusStorage = $rootScope.dashboardStatus;
          console.log("it is finished")
        });
      });
      return [200, { authorizationToken: $sessionStorage.token}];

The issue I'm facing with this code is that it returns the value before completing the function. How can I ensure that the function completes first before returning the value?

This code is part of my app.js file, so I don't have access to things like scope.watch. Are there any other ways to handle this situation?

Answer №1

When faced with a problem in my application, I came up with a solution that may not be the most conventional, but it worked for me. Essentially, I included the following code snippet inside the callback/success function of an asynchronous operation:

$rootScope.$broadcast('loaded', true);

Then, I wrapped my application logic within this event listener:

$scope.$on('loaded', function(){ //everything is loaded });

This approach helped me ensure that my application waited for the asynchronous operation to finish before proceeding. While it may not be the perfect solution, having some answer is better than none at all.
