![]() The Working with Tabs sections goes over this in more detail. This happens because each tab in a mobile app is treated as its own stack. However, pressing the back button on the Ted Lasso view should bring us back to the root Originals view. Why is this non-linear routing? The previous view we were on was the Search view. At this point, we have started using non-linear routing. Then, we tap the Originals tab again and are brought back to the Ted Lasso view. Tapping a card brings us to the Ted Lasso view within the Originals tab.įrom here, we switch to the Search tab. In the example above, we start on the Originals tab. The following is an example of non-linear routing: Non-linear routing means that the view that the user should go back to is not necessarily the previous view that was displayed on the screen. Non-linear routing is a concept that may be new to many web developers learning to build mobile apps with Ionic. This is where non-linear routing comes into play. ![]() ![]() The downside of linear routing is that it does not allow for complex user experiences such as tab views. Linear routing is helpful in that it allows for simple and predictable routing behaviors. ![]() When we press the back button, we follow that same routing path except in reverse. The application history in this example has the following path: The following is an example of linear routing in a mobile app: Linear routing means that you can move forward or backward through the application history by pushing and popping pages. If you have built a web app that uses routing, you likely have used linear routing before. Linear Routing versus Non-Linear Routing Linear Routing The interface gives us type safety and code completion inside of the component. Note how we use a TypeScript interface to strongly type the props object. We obtain the id param here and display it on the screen. The match prop contains information about the matched route, including the URL params. We can define a fallback route by placing a Route component without a path property as the last route defined within an IonRouterOutlet. Fallback Route Ī common routing use case is to provide a "fallback" route to be rendered in the event the location navigated to does not match any of the routes defined. Any other component should be rendered either as a result of a Route or outside of the IonRouterOutlet. When navigating between the two pages, the IonRouterOutlet provides the appropriate platform page transition and keeps the state of the previous page intact so that when a user navigates back to the list page, it appears in the same state as when it left.Īn IonRouterOutlet should only contain Routes or Redirects. The DashboardPage above shows a users list page and a details page. When a page is in an IonRouterOutlet, the container controls the transition animation between the pages as well as controls when a page is created and destroyed, which helps maintain the state between the views when switching back and forth between them. The IonRouterOutlet component provides a container for Routes that render Ionic "pages". These routes are grouped in an IonRouterOutlet, let's discuss that next. This is possible because of the component, which is a placeholder for the elements that should be rendered on the child routes / paths.Here, match.url contains the value of "/dashboard", since that was the URL used to render the DashboardPage. App.tsx import React from 'react' import export default App īy looking at the code above, you may have noticed that React Router supports nested routing where you can define routes for different parts of your application with different layouts.
