1. Keep controllers small and focused: It is recommended to keep controllers small and focused on a specific task or functionality. This helps in maintaining code readability and reusability.
2. Use controllerAs syntax: Instead of using the $scope object, it is recommended to use the "controllerAs" syntax. This allows you to bind properties and methods directly to the controller instance, making it easier to understand and manage the scope.
3. Minimize logic in controllers: Controllers should primarily be responsible for handling the view logic and delegating business logic to services. Keeping the controller logic minimal helps in separating concerns and makes the code more maintainable.
4. Use services for data manipulation: Instead of manipulating data directly in the controller, it is recommended to use services to handle data manipulation and retrieval. This promotes code reusability and separation of concerns.
5. Avoid using $scope.$watch: Using $scope.$watch can lead to performance issues and make the code harder to understand. Instead, use the "controllerAs" syntax and bind properties directly to the controller instance.
6. Use dependency injection: AngularJS provides dependency injection, which allows you to easily inject dependencies into your controllers. This promotes code modularity and testability.
7. Use the "controllerAs" syntax with nested controllers: When using nested controllers, it is recommended to use the "controllerAs" syntax to avoid scope inheritance issues and make the code more readable.
8. Use controller lifecycle hooks: AngularJS provides lifecycle hooks such as $onInit, $onChanges, and $onDestroy. Utilizing these hooks can help in managing the controller’s initialization, data changes, and cleanup.
9. Use controller inheritance sparingly: While AngularJS supports controller inheritance, it is recommended to use it sparingly as it can lead to complex and hard-to-maintain code. Instead, consider using services or components for code reuse.
10. Test controllers thoroughly: Controllers play a crucial role in the application’s logic, so it is important to thoroughly test them. Use unit testing frameworks like Jasmine or Karma to write tests for your controllers and ensure their functionality is working as expected.
