If my directive is defined as:
myapp.directive('directivename', ...
return {
...
restrict: 'E',
controller: MyController,
...
}
function MyController($scope, $somethingelse) {
// Controller code goes here
}
);
How can I prevent MyController from being destroyed during minification?
I'm encountering the following error message:
Error: [$injector:unpr] Unknown provider: eProvider <- e
To solve this issue, consider using explicit dependency annotation instead of implicit annotation. This will prevent any problems during minification. You have the option to use $inject or inline array annotation to specify the dependencies in your directive.
MyController.$inject = ['$scope', '$somethingelse'];
function MyController($scope, $somethingelse) {
// Controller contents go here
}
In the directive:
return {
...
restrict: 'E',
controller: ['$scope', '$somethingelse', MyController],
...
}
You can also register your controller using the .controller syntax:
app.controller('MyController', ['$scope', '$somethingelse', MyController]);
Then, you can define the controller name in the directive rather than the constructor:
return {
...
restrict: 'E',
controller: 'MyController',
...
}
If you prefer a different approach, check out ng-annotate, which eliminates the need for explicit annotation.
In most cases, the common practice involves the following method:
myapp.controller('MyController', ['$scope', '$anothervariable', function($scope, $anothervariable) {
...
}]);
This is done in order to prevent any potential issues.
Here is an example of how you can implement it:
const myDirective = {
restrict: 'EA',
template: ...,
scope: {},
controller: ["$scope","$rootScope", function ($scope,$rootScope) {
// your code goes here
}],
link: function (scope) {
// additional logic here
}
}
return myDirective;
