When the user navigates to a different route, we may need to update the component’s data or perform some other action. Vue Watch Route Change In Component: In a Vue application, it is common to have multiple components that are rendered based on the current route. Once the user is authenticated, we set the authentication token in local storage using tItem(‘token’, ‘my-auth-token’), and then redirect the user to the dashboard page using this.$router.push(‘/dashboard’).ĭon´t forget to check out my article about Vue Router Sub Routes With Vue js Nested Routes. In the above code, we have defined a login method that performs the authentication logic (which can be replaced with a call to an API or backend service). In-component navigation guards: These are defined inside the component and apply only to that component’s route.įirst, we’ll define our routes in router.js file:.Per-route navigation guards: These are defined on a per-route basis and apply only to the specified route.Global navigation guards: These are defined at the root Vue instance and apply to all routes in the application.In Vue.js, there are three types of navigation guards: These functions can be used to perform checks and validations, redirect users, or cancel navigation altogether. What Is A Navigation Guard? Navigation guards are functions that are executed before or after a user navigates to a particular route or page. When building web applications, it is often necessary to control access to certain routes or pages based on a user’s authentication status, role, or other conditions. Finally, we call the next method to indicate that we are ready to navigate to the next route.ĭon´t forget to check out my article about Learn Vue Router Query Params With Vue Query Examples Navigation Guards We then call the $destroy method on the component to destroy it. In this hook, we get a reference to the current component using the $refs property. This hook is called before the user navigates away from the current route. In the script section of the main component, we define a beforeRouteLeave hook. This element is used to display the components that correspond to the current route. In this example, we have a main Vue component that contains a element. To achieve this, we can use Vue Router’s navigation guards to trigger a scroll to top action on route change. When navigating from the Home page to the About page, we want the page to scroll to the top automatically. Let’s consider an example of a Vue JS application with two routes: Home and About. Vue JS Scroll To Top On Route Change Example However, when navigating to a different route, the page should automatically scroll to the top to provide a better user experience. Vue JS Scroll To Top On Route Change: When developing a single page application (SPA) using Vue JS, it is common to have multiple routes.Įach route may have a different set of content and may require the user to scroll down to view it. This is achieved using the watch hook that is defined in the ContentArea component.ĭon´t forget to check out my article about How To Use Vue Router Push In Vue js. Now, when the user navigates to a new route, Vue Router will detect the route change and reload the ContentArea component with new data based on the current route. Please check the Advanced Matching documentation to explore them.This code creates a new Vue instance, configures it to use our router, and mounts the root App component to the #app element in the HTML file. Vue Router uses its own path matching syntax, inspired by the one used by express, so it supports many advanced matching patterns such as optional params, zero or more / one or more requirements, and even custom regex patterns. ![]() If you are using History mode, make sure to follow the instructions to correctly configure your server as well. ![]()
