In the following example, we are using the <Image> component to lazy load images. The first image will be lazy loaded, while the second image will be eagerly loaded.import Image from 'next/image'; export default
这时候可用Next.js提供的LazyLoading来解决这类问题。让模块和组件只有在用到的时候在进行加载,一般我把这种东西叫做“懒加载”。它一般分为两种情况,一种是懒加载(或者说是异步加载)模块,另一种是异步加载组件。他们使用的方法也稍有不同,下面我们就来分别学习一下。 懒加载模块 这里使用一个在开发中常用的模块...

一、使用限制 容器组件要求:必须在特定容器组件(List、Grid、Swiper、WaterFlow)内使用,且这些组件支持配置cachedCount属性实现按需加载。 数量限制:容器组件内只能包含一个LazyForEach。 子组件规则:每次迭代必须且只能创建一个子组件,且生成的子组件必须符合父容器
Furthermore, actions that would help optimize our page load time, like events that are dependent on whether a user scrolls to a particular portion of our webpage, are some of the use cases of lazy loading. As we continue with this article, we will learn more about other use cases in re...
另外,也可参考 Vite 的 preload error 实现,自行在 loadError 内 dispatch 事件,之后在需要监听的地方处理即可。 二、自动检测新版本是否发布方案 还可参考https://github.com/umijs/umi/issues/10171中的方案,在后台轮询 html 内容,在 html 中或其他位置维护新的版本标识,发版后将自动提示用户刷新页面。
