<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">micro-app是京东零售推出的一款微前端框架,它基于类WebComponent进行渲染,从组件化的思维实现微前端,旨在降低上手难度、<span style="color: black;">提高</span>工作效率。它是<span style="color: black;">日前</span>接入微前端成本最低的框架,并且<span style="color: black;">供给</span>了JS沙箱、样式隔离、元素隔离、预加载、虚拟路由系统、插件系统、数据通信等一系列完善的功能。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">micro-app与技术栈无关,对前端框架<span style="color: black;">无</span>限制,任何框架都<span style="color: black;">能够</span><span style="color: black;">做为</span>基座应用嵌入任何类型的子应用。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">微前端的概念<span style="color: black;">是由于</span><span style="color: black;">思特沃克软件技术(北京)有限<span style="color: black;">机构</span> </span>ThoughtWorks 在2016年提出的,它借鉴了微服务的架构理念,核心在于将一个庞大的前端应用拆分成多个独立灵活的小型模块应用,<span style="color: black;">每一个</span>应用都<span style="color: black;">能够</span>独立<span style="color: black;">研发</span>、独立运行、独立<span style="color: black;">安排</span>,再将这些小型应用融合为一个完整的应用,<span style="color: black;">或</span>将<span style="color: black;">本来</span>运行已久、<span style="color: black;">无</span><span style="color: black;">相关</span>的几个应用融合为一个应用。微前端既<span style="color: black;">能够</span>将多个项目融合为一,又<span style="color: black;">能够</span>减少项目之间的耦合,<span style="color: black;">提高</span>项目扩展性,相比一整块的前端模块仓库,微前端架构下的前端模块仓库倾向于更小更灵活。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">此时此刻, <strong style="color: blue;"><span style="color: black;">京东前端<span style="color: black;">研发</span>团队<span style="color: black;">开发</span></span>MicroApp</strong> 诞生。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">它<span style="color: black;">重点</span><span style="color: black;">处理</span>了两个问题:</p>1、随着项目迭代应用越来越庞大,难以<span style="color: black;">守护</span>。2、跨团队或跨<span style="color: black;">分部</span>协作<span style="color: black;">研发</span>项目<span style="color: black;">引起</span>效率低下的问题。<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">千言万语介绍 <strong style="color: blue;">MicroApp,不如一张图介绍更让粉丝们理解深刻,<span style="color: black;">详细</span>如下图:</strong></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">single-spa是<span style="color: black;">经过</span>监听 url change 事件,在路由变化时匹配到渲染的子应用并进行渲染,这个思路<span style="color: black;">亦</span>是<span style="color: black;">日前</span>实现微前端的主流方式。<span style="color: black;">同期</span>single-spa<span style="color: black;">需求</span>子应用修改渲染<span style="color: black;">规律</span>并暴露出三个<span style="color: black;">办法</span>:bootstrap、mount、unmount,分别对应初始化、渲染和卸载,这<span style="color: black;">亦</span><span style="color: black;">引起</span>子应用需要对入口文件进行修改。<span style="color: black;">由于</span>qiankun是基于single-spa进行封装,<span style="color: black;">因此</span>这些特点<span style="color: black;">亦</span>被qiankun继承下来,并且需要对webpack配置进行<span style="color: black;">有些</span>修改。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">micro-app</strong>并没有沿袭single-spa的思路,而是借鉴了WebComponent的思想,<span style="color: black;">经过</span>CustomElement结合自定义的ShadowDom,将微前端封装成一个类WebComponent组件,从而实现微前端的组件化渲染。并且<span style="color: black;">因为</span>自定义ShadowDom的隔离特性,micro-app不需要像single-spa和qiankun<span style="color: black;">同样</span><span style="color: black;">需求</span>子应用修改渲染<span style="color: black;">规律</span>并暴露出<span style="color: black;">办法</span>,<span style="color: black;">亦</span>不需要修改webpack配置,是<span style="color: black;">日前</span>市面上接入微前端成本最低的<span style="color: black;">方法</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">描述了这么多,老规矩,直接上图会<span style="color: black;">更易</span>理解,<span style="color: black;">详细</span>如下图:</p>
