In this video, Aviv Ben-Yosef demonstrates the steps that should be taken when converting a controller's code to use controller-as syntax and replacing $scope usages
- [Instructor] Now, let's change the TodoCtrl…and its encompassing directive to use controller as syntax.…Open the todo.js file in the Exercise Files.…First, I'll change the directive definition.…There are a few settings that need to be added.…I need to add the controllerAs setting…providing a name for the controller to use.…Here I use the name $ctrl…which is the default in Angular for components.…In general, it's recommended to use the same name…in all directives.…
Then, I also make sure to toggle on…the bindToController option.…This option tells Angular…to bind the different directive bindings…to the controller itself instead of the scope.…When doing this by yourself,…make sure to always add the scenics together…or you'll be in for a very fun debugging session.…Next, I will go over the controller code…and replace every usage of $scope…to store properties and functions…to use the control's instance instead of $scope.…
Aviv Ben-Yosef kicks off the course by explaining what's different in Angular 1.6, as well the different motives for upgrading. Next, he walks through how to safely upgrade an existing app. He covers going from controllers to directives, as well as component lifecycle hooks. He also goes into the architectural changes in Angular, such as one-way data flow and immutability. To wrap up, he discusses how to properly test components.
