Adding components dynamically in AngularJS from a given list

Currently, I am working on a project that will enable users to customize a template. The initial template will be comprised of components, allowing users to add or remove them as needed. While researching online, I came across options like grapeJS, but I found it to be too complex for this particular application.

I would greatly appreciate any advice on how to approach this project, as well as any resources that could assist me in the process.

To give a simple example:

The basic template will include the following components:

Header
Text Post
Single Image
Footer

The user's selection of additional components to append to the template may include options such as:

Image Slideshow
Video
2 Column Text Post
Automatic wav file player featuring "Wrecking Ball" by Miley Cyrus

In essence, users will have the ability to choose from the above list and incorporate them into the existing template. Any insights or suggestions on how to proceed in the right direction would be extremely valuable!

Answer №1

This will point you in the right direction:

Develop your Image Slideshow, Video, 2 Column Text Post, and Miley Cyrus Video as independent AngularJS components or directives.
In the directive/component where you wish to dynamically load the above components/directives, utilize $compile to compile them. Then, use $element to insert the compiled element into the DOM.

An outline of this methodology is shown below, with the assumption that myTemplate represents the primary template for your application. The directive slideshow signifies the dynamic addition of an Image Slideshow when the user clicks on Add Component.

HTML

<div>
  <my-template></my-template>
</div>

JavaScript

var myApp = angular.module('myApp',[]);

myApp.directive('myTemplate', function($rootScope, $compile) {
    return {
    controller: function($element, $scope) {
        var vm = this;
        vm.name = "name";

      vm.insert = function() {
        var elStr = "<slideshow></slideshow>";
        var newScope = $rootScope.$new();
        var insertedEl = $compile(elStr)(newScope);
        $element.append(insertedEl);
      };
    },
    controllerAs: "vm",
    template: "<h1>Header</h1><p>Body</p><footer>Footer</footer><button ng-click='vm.insert()'>Add Component</li>"
  }
});

myApp.directive("slideshow", function() {
    return {
    controller: function() {
        this.text = "THIS IS A SLIDESHOW";
    },
    controllerAs: "vm",
    template: "<h1>{{vm.text}}</h1>"
  }
});
