Tips for effectively scaling controllers in AngularJS

I have an Angular application that is currently structured with everything in one controller. I would like to split it into multiple controllers so that each controller can focus on specific actions rather than having a mixture of functions with different purposes in one controller.

Here is the existing code snippet:

    var videoApp = angular.module('videoApp', ['videoAppFilters', 'ui.unique', 'angularUtils.directives.dirPagination']);

videoApp.controller('VideoListCtrl', function ($scope, $http, $filter) {
// Controller code here
});

I am looking for guidance on how to effectively split this code into multiple controllers and how to seamlessly pass data between them.

Answer №1

If you're looking to optimize your code structure, consider organizing it into Services. For instance, you can create a Cache logic service that can be easily injected into your controller for reusability.

  • Additionally, you may want to convert certain elements into filters or directives:

For example, rather than repeatedly calling the $scope.formatDate function to format dates, you can simplify the process in your HTML by using {{ date | formatDate }} or 

<div formatDate>{{ date }}</div>
.

You could also streamline your code by potentially removing the pageSize element, depending on how detailed you want to get with your optimizations.
