The application and advantages of Vue Router Lazy-Loading routing to achieve a qualitative leap in page performance

With the continuous development of front-end technology, Web applications are also becoming more and more sophisticated. The more complex it is. For large applications, page performance is often a very important issue. A responsive page provides a better user experience and helps improve user retention. In Vue.js development, Vue Router Lazy-Loading is a very useful technology that can help us improve page loading speed and performance.

Vue Router is the routing manager officially provided by Vue.js, which can help us build single-page applications. Vue Router Lazy-Loading is a feature of Vue Router that allows us to lazy load specific routing components. This means that the relevant components will only be loaded when the user accesses a specific route. In this way, we can greatly shorten the initial loading time of the application and only load the components that the user needs, reducing unnecessary resource consumption.

Through Vue Router Lazy-Loading, we can divide the application code into a series of small modules, each module is a route. Each module can be loaded as a separate file. In this way, we can load some infrequently used pages or functions as an independent module and only load them when the user needs them. This modular loading method can significantly reduce the initial loading time and improve the response speed of the page.

Below we use a specific code example to demonstrate how to use Vue Router Lazy-Loading.

First, we need to install the Vue Router plug-in in the Vue project. It can be installed through npm, run the following command:

npm install vue-router

After the installation is completed, introduce Vue Router in the entry file of the Vue project (usually main.js):

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

Vue.use(VueRouter)

Then, we Define several components as pages of our application. Here we assume that we have two routes, corresponding to two pages:

import HomePage from './pages/HomePage.vue'
import AboutPage from './pages/AboutPage.vue'

Next, we configure the routing table and use the lazy loading feature of Vue Router. When configuring routing, we do not need to introduce components directly, but use dynamic introduction:

const routes = [
  {
    path: '/',
    component: () => import('./pages/HomePage.vue')
  },
  {
    path: '/about',
    component: () => import('./pages/AboutPage.vue')
  }
]

Finally, we create a Vue Router instance and pass the routing table as a parameter:

const router = new VueRouter({
  routes
})

Now, we have completed the configuration of Vue Router. We can mount the router instance to the Vue instance for use in the application:

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

Through the above code example, we can see how Vue Router Lazy-Loading is used. Each component is loaded dynamically and is loaded only when the user accesses a specific route. In this way, we can reasonably split the application code and improve the page loading speed and performance.

The application of Vue Router Lazy-Loading can not only improve page performance, but also has some other advantages. First, it can reduce the file size of the initial load and improve the responsiveness of the page. Secondly, it can implement on-demand loading, loading only the components currently needed by the user, reducing the loading of useless components and resource consumption. Finally, it can make the project's code structure clearer and easier to maintain, and improve development efficiency.

In short, Vue Router Lazy-Loading is a very useful technology that can help us improve page performance. By rationally using Vue Router Lazy-Loading, we can achieve a qualitative leap in page loading speed, improve user experience, and reduce resource consumption.
