You can always update your selection by clicking Cookie Preferences at the bottom of the page. Finally, normal use of .trigger or .delegate causes the default action of the event to be cancelled. Whenever the contact detail screen successfully saves a contact, we'll publish the ContactUpdated message and whenever the end user begins viewing a new contact, we'll publish the ContactViewed message. Below that we have the application's main container div. Next, let's just add a placeholder module for our contact detail screen, so we can satisfy the build. Why? First, take a look at the require elements at the top of the view. So, we've added one of those so that we can toggle the NProgress indicator off and on, based on the value of that property. This has two columns. This route will cause the no-selection module to load. Create a real backend for the app and use the. If you haven't stopped/restarted it after editing the bundles, then you will need to do that now. Copyright © 2010 - 2020 Blue Spire Inc. Code licensed under the MIT License. Instead, we can just refer to the route by name. To handle this, we're going to increase the amount of information in our system by introducing pub/sub. If nothing happens, download GitHub Desktop and try again. This is a special API that is used in Aurelia Webpack projects to allow Webpack to identify strings that represent modules. So, let's build out the real detail component. If you recall, our route pattern for the contact details screen was contacts/:id. If the canDeactivate hook returns true, navigation is allowed; if false is returned, it is prevented and the route state is reverted. Just change directory into the project folder and run it by typing au run --open. Thus, when the user clicks on the contact, we immediately select the contact in the list and then the href is allowed to trigger the router, causing a navigation to the selected contact. they're used to gather information about the pages you visit and how many clicks you need to accomplish a task. Finally, we have a select method for selecting a contact. We would like to be able to bind the indicator to the request state of our API, so we need to make that available in our App class. First, we're using dependency injection. First, we are using a custom attribute provided by Aurelia's routing system: route-href. Let's create a couple of messages that our contact-detail component can publish and then let the contact-list subscribe to those and respond appropriately. Let's go ahead and build that out, as a contact-list custom element. First, notice that we've set the config.title property. HTML5 History API enables modifying a website's URL without a full page refresh. The second contains a router-view custom element. The router generates a navModel for each routeConfig. In your own apps, you can use any CSS framework you like. When you run the application, you should see something similar to this: We've got the basic visual structure of our application in place and routing is now working. To accomplish this, we use the select method to track the selected contact's id, which allows us to instantly apply the selection style. The second argument passed to activate is the routeConfig.
