Question

When I use a minified version of AngularJS, the error messages become completely

Upon using angular.js, I encountered the following stack trace:

[$injector:unpr] Unknown provider: editorPopupManagerProvider <- editorPopupManager <- libStateManager <- libInjectionManager
http://errors.angularjs.org/1.2.2/$injector/unpr?p0=editorPopupManagerProvider%20%3C-%20editorPopupManager%20%3C-%20libStateManager%20%3C-%20libInjectionManager

And when utilizing angular.min.js, this was the resulting stack trace:

[$injector:unpr] http://errors.angularjs.org/1.2.2/$injector/unpr?p0=editorPopupManagerProvider%20%3C-%20editorPopupManager%20%3C-%20libStateManager%20%3C-%20libInjectionManager

Although a simple example, at times the minified error provides little assistance.

In both scenarios - with angular.js and angular.min.js, I anticipate encountering the initial stack trace. The deliberate introduction of this issue in my code highlights the challenge posed by angular.min.js's obscured stack trace, making comprehension difficult. While I appreciate the intent behind obscuring stack traces from end users, for logging purposes, I require clear, readable stack traces to be sent to a logging server.

Answer №1

If your provider name is unknown, it may be due to manipulation or minification. To correct this issue, use the following syntax:

myApp.controller('MyCtrl' ['$scope', function ($scope) {
    // utilize '$scope'
}]);

Ensure that the function is enclosed in an Array to maintain dependency naming conventions and prevent mangling of Strings:

myApp.controller('MyCtrl' ['$scope', function (a) {
    // work with 'a'
}]);

Add additional dependencies in the specified order:

myApp.controller('MyCtrl' ['$scope', 'MyService', function ($scope, MyService) {
    // perform tasks...
}]);

If you happen to be using the array declaration for your controllers, it is likely that this will apply to some of your Directive declarations as well. Typically, we would do something like this:

.controller('MyGreatCtrl',
[       '$scope','$stateParams', // even when minified, injection is done correctly
function($scope , $stateParams ,) {
    ...

The code above should function properly, even after being minified.

However, the same approach should also be taken with Directive declarations. It can be done incorrectly like this (issues arise when minified):

.directive('myGreatDirective',
    [function () {
        var directive =
        {
            restrict: 'E',
            ...
            controller: function ($scope , $element , $attrs) {
                ...
                };
            }],
        };
        return directive;

The correct way to do it is as follows:

.directive('myGreatDirective',
    [function () {
        var directive =
        {
            restrict: 'E',
            ...
            // Use Array declaration here as well
            controller: ['$scope','$element','$attrs',
                function ($scope , $element , $attrs) {
                    ...    
                };
            }],
        };
        return directive;
