watchers-execution - require and specify consistent use $scope.digest() or $scope.apply()

For the execution of the watchers, the $digest method will start from the scope in which we call the method. This will cause an performance improvement comparing to the $apply method, who start from the $rootScope

Examples

The following patterns are considered problems when configured "$apply":

/*eslint angular/watchers-execution: [2,"$apply"]*/

// invalid
$scope.$digest(); // error: Instead of using the $digest() method, you should prefer $apply()

The following patterns are not considered problems when configured "$apply":

/*eslint angular/watchers-execution: [2,"$apply"]*/

// valid
$scope.$apply(function() {
    // ...
});

The following patterns are considered problems when configured "$digest":

/*eslint angular/watchers-execution: [2,"$digest"]*/

// invalid
$scope.$apply(function() {
    // ...
}); // error: Instead of using the $apply() method, you should prefer $digest()

The following patterns are not considered problems when configured "$digest":

/*eslint angular/watchers-execution: [2,"$digest"]*/

// valid
$scope.$digest();

Version

This rule was introduced in eslint-plugin-angular 0.4.0
