What are the steps for configuring my Angular directive in this specific scenario?

Looking to create a directive that implements isolate scope.

Here's the code snippet:

angular.module('myApp').directive('itemCollection',  ['$cookies',     
    function($cookies) {
        return {
            restrict: 'E',
            scope: {
                items: '='
            },
            link: function(scope) {
                    console.log(scope.items)
                    console.log(items)
                    --> both console.log show undefined
            }
        };
    }
]);

HTML Template

<item-collection items="item1"></item-collection>

Struggling to retrieve 'item1' in the directive and it remains undefined. Unsure of what might be causing this issue. Would appreciate any help on this matter. Thank you!

Is item1 received asynchronously? If so, you should create a watch in your directive to handle it as soon as it becomes available.

    return {
        restrict: 'E',
        scope: {
            items: '='
        },
        link: function(scope) {
                console.log(scope.items)
                console.log(items)
                --> both console.log show undefined

            scope.$watch(
                function() { return scope.items; },
                function(newValue) {
                    if (newValue != null) {
                        console.log('not null:' + newValue);
                    }
                    else {
                        console.log('still null, skip');
                    }
                }
            );
        }
    };
