![]() ![]() What exactly do I mean by nested routing? Much like the top-level routing that's so common, nested routing lets you define routes that are children of other routes. So far, I've concentrated on top-level routing, but a common need is for nested routing. Although this is used for a catch-all mechanism in many apps, you can also use this to match any route by regular expression. This only works because the routes are matched in order: const routes = [īy making the catch-all route last, you can specify that if none of the routes are matched, you just send them to the home page (alternatively you can send them to a specific not-found component if you prefer). However, if I comment the name out and uncomment it on the parent, it wont render the ProductComments component and will give me the warning: The route named 'ProductComments' has a child without a name and an empty path. ![]() In this example, if the route matches anything, you're redirecting back to the root of your application. With the above configuration, Vue Router will render my ProductComments component if I visit /comments. Instead of a simple route string, you can use a path with a parameter of pathMatch to match the route: In the Vue Router, you can do that with pathMatch in a route. Sometimes you need to use regular expressions to match the routes you want. Assuming that you have at least one component, you can start creating your routes like so: // router/index.js The purpose of the Router is to define a set of rules to map URL patterns to individual components. Now that it's installed, you can create your router. You can install it with npm: npm install vue-router -save To get started, you'll need this package. It's entirely optional, but in many cases, you'll want to leverage the package. Routing in Vue is handled by a separate package from the core Vue package. With that in mind, let's see how Vue implements routing. This also means that because the location inside your application is defined by the URL, that you can share these URLs to allow for deep linking into an application. This is accomplished differently in different frameworks, but the basic strategy is the same: The URL defines what content the SPA shows to the user. As the URL changes, instead of a network request for other page, the SPA recognizes the change and changes the view. The IonRouterOutlet component uses the popular Vue Router library under the hood. ![]() As you can see in Figure 1, Routing allows your Single Page Application to define a section of the app to show individual views. This guide covers how routing works in an app built with Ionic and Vue. You have views in your Vue project and want to be able to navigate to individual views. If you think about how websites traditionally work, you could navigate from the home page to other pages in the site. In many Vue projects, you'd like the ability to navigate to different parts of your application. It allows you to build the kinds of apps you need to create. Most of our applications are driven by multiple views and some kind of navigation. We call them SPAs (single page applications), but that's rarely the real case. ![]()
