Two paths in AngularJS

In the AngularJS application, the ui-router is used to manage two types of pages:

  1. Pages with routes explicitly specified in routes.js
  2. Pages with routes dynamically derived on demand

Upon loading the page, the application sends a request for data (type, variables). The challenge is how to load the template and controller of the page based on its type?

/**
Although there is an option available with this routing, it may impact the explicitly specified routes.
*/
/* routes.js */
// Definition of the "page" state

/* PageController.js */
// Obtain the type of page
$scope.type = res.data.type;

/* page.jade */
div(ng-if=«page.type == ‘index’»)
    div(ng-controller=‘IndexController’)
div(ng-if=«page.type == ‘catalog’»)
    div(ng-controller=‘IndexController’)

The process of loading templates is not clearly defined, raising concerns about the performance of this solution. Is there a more efficient approach available?

Answer №1

To display the desired page, implement the logic in your IndexController and save this data in the scope.

In your view, utilize ngIf along with ngInclude to dynamically load templates based on your variable's value.

Refer to the example below.

routes.js

angular.module('yourApp', ['ngRoute', ...])
    .config(function($routeProvider){
        $routeProvider
            .when('/', {
                templateUrl: 'template0.html',
                controller: 'IndexController'
            });
    });

template0.html

<div ng-if="page.type == 'index'">
  <div ng-include="template1.html"> ... </div>
</div>
<div ng-if="page.type == 'catalog'">
  <div ng-include="template2.html"> ... </div>
</div>

In both scenarios, the controller will already be loaded for template0.html.
