Selecting a directive's scope

Though the title may not capture it quite accurately, I struggled to find a more fitting description.

I crafted a directive that incorporates an ng-repeat:

app.directive('appDirective', function($purr){
    var template = '' +
        '<div ng-repeat="elements in queue">' +            
        '</div>';

    return{
        template: template
    }
});

If my understanding is correct, there are two ways I can provide the queue to my directive

1: via the linking function

    return{
        restrict: 'A',
        template: template,
        link: function(scope){
                scope.queue =[];
        }
    }

2: through the controller

    return{
        restrict: 'A',
        template: template,
        controller: directiveCtrl
    }

app.controller('directiveCtrl',function($scope){
    $scope.queue = [];
});

Which method should I select and what are the reasons behind that choice?

Answer №1

When it comes to the directive's link function and controller function, there is minimal distinction between the two. Generally, you can include methods, $watches, and other functionalities in either of them. However, keep in mind that the controller will execute first, which can be crucial at times. For consistency with the framework, consider placing scope-manipulation functions inside the controller.

To observe when the controller and link functions are executed within two nested directives, check out this demo on JSFiddle.

For further insights, explore the discussion on the variances between the 'controller', 'link', and 'compile' functions while defining a directive.
