What are the lazy loading methods of Vue?

Vue implements lazy loading methods including Vue Router lazy loading, Vue asynchronous components, and Vue’s v-lazy instruction. Detailed introduction: 1. Vue Router lazy loading: Vue Router allows components to be loaded on demand to reduce the initial loading time. Lazy loading can be achieved through Webpack's import syntax; 2. Vue asynchronous components: Vue provides asynchronous components. To implement lazy loading, you can use the Vue.component method to define asynchronous components and so on.

In Vue, you can use the following methods to implement lazy loading:

• Vue Router lazy loading: Vue Router allows you to load components on demand to reduce initial loading time . You can implement lazy loading through Webpack's import syntax, for example:

const Foo = () => import('./Foo.vue')

In this way, the corresponding component will be loaded only when the route is accessed.

Vue.component('my-component', (resolve) => { require(['./MyComponent.vue'], resolve) })

In this way, the component will not be loaded in advance before it is used.

computed: { imageSrc() { // 根据滚动位置和其他逻辑来决定图片的src return 'lazy-image.jpg' } }

In this way, the image will be loaded when the image enters the visible area.

The above are commonly used lazy loading methods in Vue. You can choose the appropriate method to implement the lazy loading function according to your own needs.
