I'm trying to identify if I understand some core concepts in AngularJS. If I have a line of code that says:
.controller('MyCtrl', function($scope) {
and I change it to:
.controller('MyCtrl', function($scope, $myService) {
Is it correct to say that "$myService was injected into MyCtrl". Or is it more correct to say that "$myService is injected as a dependency of MyCtrl"? Or, should it be said some other way entirely?
Thank you so much!
Either are fine. In your example, myService was injected into MyCtrl as a dependency of MyCtrl.
One note, though. You shouldn't name your services with a dollar sign at the beginning as that is reserved for providers within the Angular source code.
Instead, do:
.controller('MyCtrl', function($scope, MyService) {
It is correct to say that you inject service in a controller as you would be using service methods in that controller, either as a data transfer across multiple controllers or by getting it via server.
It is recommended to inject service using this notation
.controller('MyCtrl', ['$scope','$myService',function($scope, $myService) {}]);
As when you minify your controller js then it will give no errors in this format.
A service is a way to maintain common state between several controllers, so yes, injecting a service into a controller is entirely correct.
