Delaying Angularjs Route Change Until Model Loaded To Prevent Flicker

Have you ever experienced that annoying flicker on your AngularJS web application when the route changes before the data is fully loaded? It can be frustrating, not to mention distracting for your users. But fret not, because I've got just the solution for you!

The key to eliminating this flickering effect is to ensure that the route change in your AngularJS app only happens once the data model is fully loaded. By delaying the route change until the model is ready, you can provide a smooth and seamless user experience without any flickering or jarring transitions.

So, how exactly can you achieve this in your AngularJS application? Let's walk through the steps to delay the route change until the model is loaded:

Step 1: Identify the Route Change Trigger
First things first, you need to determine the point in your AngularJS application where the route change is triggered. This is usually when a user clicks on a link or button that navigates to a different route.

Step 2: Delay the Route Change
Once you've identified the route change trigger, you can implement a mechanism to delay the actual route change until the model is fully loaded. One way to do this is by using AngularJS's built-in Resolve property in the $routeProvider configuration.

Step 3: Implement Resolve Property
To delay the route change until the model is loaded, you can use the Resolve property in the $routeProvider configuration. This property allows you to specify a list of dependencies that must be resolved before a route change can occur.

Here's an example of how you can implement the Resolve property to delay the route change until the model is fully loaded:

Javascript

$routeProvider
  .when('/your-route', {
    templateUrl: 'your-template.html',
    controller: 'YourController',
    resolve: {
      data: function(DataService) {
        return DataService.getData().$promise;
      }
    }
  });

In this example, the 'data' dependency is resolved by calling the getData() method from a hypothetical DataService. Once the data is loaded (using $promise in this example), the route change will proceed, preventing any flickering effect.

Step 4: Handle Loading States
It's essential to handle loading states appropriately to provide feedback to users while the data is being fetched. You can display a loading indicator or spinner until the model is loaded to keep users informed and engaged.

By following these steps and implementing the Resolve property in your $routeProvider configuration, you can effectively delay the route change in your AngularJS application until the model is fully loaded, eliminating any flickering and providing a seamless user experience.

So, go ahead and give this a try in your AngularJS project to ensure that your users enjoy a smooth and flicker-free browsing experience!
