How to refresh the page in Vue application

Vue is a popular JavaScript framework and a development tool for building interactive web applications. Vue provides many useful features and tools, including Vue Router. Vue Router is a built-in routing manager that helps developers better manage routing in Vue applications. Although Vue Router is a very powerful and convenient tool, Vue Router will not respond when the current page needs to be refreshed. In this article, we will explain how to refresh a page in a Vue application.

Vue Router

Before starting to introduce how to refresh the page, you first need to understand Vue Router. Vue Router is a routing management tool officially provided by Vue.js, which can easily manage routing in Vue applications. Using Vue Router, developers can define a set of routing rules and map them to components. When the user accesses these paths, Vue Router will take care of switching to the correct component in the Vue application. Vue Router can also provide many other features, such as route nesting and route guards.

In order to use Vue Router, you need to install it through npm first. Enter the following command in the terminal:

npm install vue-router --save

After the installation is complete, introduce and use Vue Router in the entry file of the Vue application. For example:

import Vue from 'vue'
import VueRouter from 'vue-router'

Vue.use(VueRouter)

const router = new VueRouter({
  routes: [
    // 定义路由规则
    { path: '/', component: Home },
    { path: '/about', component: About }
  ]
})

new Vue({
  router,
  render: h => h(App)
}).$mount('#app')

Here, we configure the Vue Router and bind it to the Vue instance. Now, we can use the <router-link></router-link> tag in Vue components to define links, and use the <router-view></router-view> tag to render these components.

Refresh page

Vue is a single page application (SPA), and all its routes are loaded and switched in the same page. In this case, Vue will become unresponsive when the user clicks the browser's refresh button, or manually enters the URL and presses the enter key.

In order to solve this problem, we can use JavaScript's location object to refresh the page. In Vue Route, we can use the $router.go(0) method to refresh the current page. This method will return Vue Router to the current path, thereby re-rendering the page.

methods: {
  refreshPage() {
    this.$router.go(0)
  }
}

Here, we define a refreshPage method, which is called to refresh the page when the user clicks the button. When this method is called, Vue Router will reload the component at the current path, thereby re-rendering the page.

Summary

Vue Router is a very important module in Vue.js, which can help developers better manage routing in Vue applications. Although Vue Router is a very powerful and convenient tool, Vue Router will become unresponsive when the current page needs to be refreshed. But by using JavaScript's location object and using the $router.go(0) method to refresh the current page, we can solve this problem.
