Navigating through components/controllers in Angularjs to access objects

I'm working on sharing objects between controllers in AngularJS and while I've come up with a solution that works, it doesn't feel very elegant to me. I'm curious if there is a better way to accomplish this task rather than the one I have implemented.

Specifically, in componentA, I have an object that needs to be accessed from componentB.

app.component("componentA", {
    controller: function ($scope, $rootScope, $compile) {

        //the object that needs to be shared
        $scope.objectToAccess = {name: 'object', value: 3};

        //listens for broadcast from componentB and passes the object
        $rootScope.$on("getObject", function () {
            $rootScope.$broadcast('receiveObject', $scope.objectToAccess);
        });
    }
}

app.component("componentB", {
    controller: function ($scope, $rootScope, $compile) {

        $scope.object = {name : null, value: null};

        //receives the broadcasted object and assigns its value
        $rootScope.$on("receiveObject", function (event,object) {
            console.log(object);
            $scope.object = object;
        });

        //broadcasts to request the object's contents
        $rootScope.$broadcast('getObject');   
    }
}

The current setup works, but I find it too complex with all the back and forth communication. Are there any Angular features specifically designed for handling such scenarios, or is my approach justified?

Answer №1

Personally, I believe $scope events are best utilized when observing data changes rather than actively requesting them.

Alternatively, consider utilizing a service to store and reference data within controllers. Services act as singletons, allowing both controllers to access the same instance of data and easily share information.
