The role of Router in Vue

Vue Router is the official routing management library of Vue.js. It allows Vue applications to manage navigation between pages, creating single page applications (SPA).

Main functions:

• Manage page navigation: Router allows users to switch between different pages without reloading the entire application program.
• URL Management: It synchronizes the state of the application with URLs so that users can easily access specific pages through URLs.
• Component reuse: Router allows Vue components to be reused in different pages, thereby improving the maintainability and scalability of the code.
• State Management: Router can store routing information and data, including query parameters and metadata, which helps manage application state.
• Guards: Router provides navigation guards that allow custom code to be executed before or after navigation occurs, such as authentication checks or data prefetching.

How to use Vue Router:

1. Installation: Install vue-router in the project Bag.
2. Create Router: Use the VueRouter class to create a routing instance and configure the routing table (mapping URL paths to components).
3. Using Router: Use the <router-view></router-view> component in a Vue application to render components matching the current route.
4. Navigation: Use the $router object for navigation, for example by using the push() or replace() method Change URL.

Vue Router is a powerful tool for building SPA because it simplifies navigation management, improves URL management, promotes component reuse, and provides rich functionality such as state management and navigation guards.
