Having previously integrated jquery with Vaadin in custom components multiple times, I am curious to see an example of AngularJS integration with Vaadin.
Furthermore, I would like to confirm if AngularJS is compatible and functioning properly with IE9.
If you're interested in seeing an example of integrating Vaadin and AngularJS, check out the link here.
One of the main challenges is aligning the $scope for AngularJS with Vaadin. The JavaScript code invoked by Vaadin operates outside of AngularJS's dependency injection and scope management, creating a unique hurdle to overcome.
Typically, AngularJS assumes that the page's HTML is parsed once and connected to AngularJS. However, with Vaadin, the page's HTML primarily exists as a means to initialize Vaadin components and lacks the direct linkage expected by AngularJS. This requires a method to dynamically create new AngularJS-connected elements and controllers when needed.
To address this issue, vaangular implements a solution using the 'innerModuleName' module defined within angular.module through two specific steps:
Firstly, a new scope within AngularJS is established by utilizing:
angular.injector([ 'ng', innerModuleName ]).invoke(function($compile, $rootScope) {
Secondly, the scope (referred to as scpe) and DOM elements are combined using:
var connectorElement = angular.element(connector.getElement());
var cmp = $compile(templateElement);
scpe = $rootScope.$new(false);
cmp(scpe);
scpe.$digest();
connectorElement.append(templateElement);
At the conclusion of this process, a newly integrated portion of the DOM is now linked to a corresponding controller.
This approach enables the incorporation of Vaadin Connector functionality within an AngularJS environment seamlessly.
After reading up on this, it seems like React aggregates all DOM changes before making them. Couldn't Angular employ a similar mechanism? It already knows which DOM nodes need to be altered after the digest cycle -- why not coordinate the updates alto ...
