@ngdoc error
@name $injector:cdep
@fullName Circular Dependency
@description
This error occurs when the {@link angular.injector $injector} tries to get
a service that depends on itself, either directly or indirectly. To fix this,
construct your dependency chain such that there are no circular dependencies.
For example:
```
angular.module('myApp', [])
.factory('myService', function (myService) {
// ...
})
.controller('MyCtrl', function ($scope, myService) {
// ...
});
```
When an instance of `MyCtrl` is created, the service `myService` will be created
by the `$injector`. `myService` depends on itself, which causes the `$injector`
to detect a circular dependency and throw the error.
For more information, see the {@link guide/di Dependency Injection Guide}.
