Practical experience of Vue Router Lazy-Loading routing to reach the peak of page performance requires specific code examples
1. Introduction
With the order As page applications become increasingly popular, performance becomes a critical issue. In large projects, there are often many complex routing pages, and loading all related components at once will have a negative impact on the speed of the initial load and overall performance. In order to solve this problem, Vue Router provides the function of Lazy-Loading routing, allowing us to load components on demand. This article will introduce some practical experiences about Vue Router Lazy-Loading routing, and provide some specific code examples to help developers achieve optimal performance in their projects.
2. The principle of lazy loading
Lazy loading (also called on-demand loading) is a page performance optimization technology that improves the efficiency of initial loading by dynamically loading files when needed. speed and reduced resource consumption. Lazy loading in Vue Router is implemented through asynchronous components and Webpack's code splitting function. When accessing a route that requires lazy loading, Vue Router will send an asynchronous request to load the related components.
3. Practical experience
- Split components by routing
Before starting to practice lazy loading, we need to first split the components according to the granularity of routing . For large projects, a page may often contain multiple components, and we need to split these components into smaller modules to load on demand. This way, when a user accesses a specific route, only the components related to that route are loaded, rather than all components of the entire page.
- Configuring routing
In Vue Router, lazy loading components need to be implemented through the code splitting function of Webpack. We need to change the component in the routing configuration to a function that returns a Promise, and use Webpack's import function to dynamically load the component. The following is an example routing configuration:
import Vue from 'vue' import Router from 'vue-router' Vue.use(Router) const Home = () => import('@/views/Home.vue') const About = () => import('@/views/About.vue') const router = new Router({ routes: [ { path: '/', name: 'home', component: Home }, { path: '/about', name: 'about', component: About } ] }) export default router
In the above code, the Home and About components are defined as functions that return a Promise. These components will be loaded dynamically when accessing the corresponding route.
- Loading components on demand
In order for components to be loaded on demand, we need to use Vue's asynchronous components in the template. Asynchronous components allow us to specify a factory function that can return a Promise and return an instance of the component when the Promise is resolved. The following is an example of using an asynchronous component:
<template> <div> <AsyncComponent /> </div> </template> <script> export default { components: { AsyncComponent: () => import('@/components/AsyncComponent.vue') } } </script>
In the above code, the AsyncComponent component is loaded asynchronously through the import function. When this component is rendered to the page, it will be loaded dynamically.
4. Summary
Through Vue Router Lazy-Loading routing, we can load components on demand, thereby improving the performance of the page. In practice, we need to split components according to routing granularity and configure corresponding routing. At the same time, we also need to use asynchronous components to load components on demand. Through the above practical experience, developers can achieve optimal performance in their projects. I hope the code examples in this article can help readers better understand and apply the Lazy-Loading routing function of Vue Router.

Vue.js is suitable for small to medium-sized projects, while React is suitable for large projects and complex application scenarios. 1) Vue.js is easy to use and is suitable for rapid prototyping and small applications. 2) React has more advantages in handling complex state management and performance optimization, and is suitable for large projects.

Vue.js and React each have their own advantages: Vue.js is suitable for small applications and rapid development, while React is suitable for large applications and complex state management. 1.Vue.js realizes automatic update through a responsive system, suitable for small applications. 2.React uses virtual DOM and diff algorithms, which are suitable for large and complex applications. When selecting a framework, you need to consider project requirements and team technology stack.

Vue.js and React each have their own advantages, and the choice should be based on project requirements and team technology stack. 1. Vue.js is community-friendly, providing rich learning resources, and the ecosystem includes official tools such as VueRouter, which are supported by the official team and the community. 2. The React community is biased towards enterprise applications, with a strong ecosystem, and supports provided by Facebook and its community, and has frequent updates.

Netflix uses React to enhance user experience. 1) React's componentized features help Netflix split complex UI into manageable modules. 2) Virtual DOM optimizes UI updates and improves performance. 3) Combining Redux and GraphQL, Netflix efficiently manages application status and data flow.

Vue.js is a front-end framework, and the back-end framework is used to handle server-side logic. 1) Vue.js focuses on building user interfaces and simplifies development through componentized and responsive data binding. 2) Back-end frameworks such as Express and Django handle HTTP requests, database operations and business logic, and run on the server.

Vue.js is closely integrated with the front-end technology stack to improve development efficiency and user experience. 1) Construction tools: Integrate with Webpack and Rollup to achieve modular development. 2) State management: Integrate with Vuex to manage complex application status. 3) Routing: Integrate with VueRouter to realize single-page application routing. 4) CSS preprocessor: supports Sass and Less to improve style development efficiency.

Netflix chose React to build its user interface because React's component design and virtual DOM mechanism can efficiently handle complex interfaces and frequent updates. 1) Component-based design allows Netflix to break down the interface into manageable widgets, improving development efficiency and code maintainability. 2) The virtual DOM mechanism ensures the smoothness and high performance of the Netflix user interface by minimizing DOM operations.

Vue.js is loved by developers because it is easy to use and powerful. 1) Its responsive data binding system automatically updates the view. 2) The component system improves the reusability and maintainability of the code. 3) Computing properties and listeners enhance the readability and performance of the code. 4) Using VueDevtools and checking for console errors are common debugging techniques. 5) Performance optimization includes the use of key attributes, computed attributes and keep-alive components. 6) Best practices include clear component naming, the use of single-file components and the rational use of life cycle hooks.
