What role does the angular ui route helper.basepath serve?

While researching helper.basepath in Angular UI routing, I discovered that it is a special function related to the RouteHelperProvider. However, the information was sparse and didn't explain its purpose. Can you shed some light on what exactly it does?

In the following code snippet, can you clarify the difference between using:

templateUrl: 'dashboard.html' / templateUrl: 'helper.resolveFor(dashboard.html)'

state('app.dashboard', {
          url: '/dashboard',
          title: 'Dashboard',
          templateUrl: helper.basepath('dashboard.html'),
          resolve: helper.resolveFor('flot-chart','flot-chart-plugins', 'weather-icons')
      })

Answer №1

The parameter name 'helper' is simply used to refer to the RouteHelpersProvider in app.js that gets passed into App.config. To locate where the basepath and resolveFor functions are defined, search for "App.provider('RouteHelpers'" or just 'RouteHelpers'. This should give you insight into its functionality.

Answer №2

Basepath serves as a structural blueprint for web pages, offering the flexibility to be utilized across different pages and waiting to resolve any accompanying module. Additionally, the variables scoped within the controller are accessible within this basepath.

.state('myroute', {
    url: '/my-route',
    templateUrl: RouteHelpersProvider.basepath('layout-template.html'),
    controller: 'myController',
    resolve: RouteHelpersProvider.resolveFor(<modules to be resolved before the route>)
})

The scope variables set in MyController can directly interact with elements in layout-template.html.
