<h3 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">页面可视化搭建工具的技术要点</span></h3>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">从技术<span style="color: black;">方向</span>, 设计和<span style="color: black;">研发</span>一个页面可视化搭建工具时, 需要<span style="color: black;">思虑</span>以下几个技术要点:</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">页面组件化</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">页面模板</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">页面可视化编辑</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">组件层级关系</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">页面打包</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">页面的基本单元是 HTML 元素, <span style="color: black;">然则</span> HTML 元素<span style="color: black;">没法</span><span style="color: black;">包括</span>业务<span style="color: black;">规律</span>, 且由 HTML 元素直接组合出页面, 过于繁杂和低效.</span></p><img src="https://mmbiz.qpic.cn/mmbiz_png/meG6Vo0MeviarQXnEQ2u7rXibzC9old6vqpjgv5nzdSVr28xSzibiauXERtvuetun2EtqkXdW2c6Oc1fcwIlRtgECQ/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">照片</span><span style="color: black;">源自</span>: </span><span style="color: black;">https://vuejs.org/images/components.png</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">页面较好的组织方式是组件化, 如上图所示. 组件是对 HTML 元素、元素布局和样式、业务<span style="color: black;">规律</span>的封装. <span style="color: black;">经过</span>组件封装业务<span style="color: black;">规律</span>, 并<span style="color: black;">经过</span>组件属性(Props)向外暴露组件的配置字段. 采用页面组件化, <span style="color: black;">繁杂</span>的页面可视化搭建<span style="color: black;">能够</span>转化为2个较简单的操作:</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">组件树组合, 页面可视化搭建变成页面组件的可视化组合.</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">组件配置编辑, 将对页面内容的编辑转化为对组件的配置属性(props)修改.</span></p><span style="color: black;">页面前端框架</span>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">页面组件化需依靠前端框架来实现. 页面可视化搭建工具的架构方式对页面前端框架有限制: 需<span style="color: black;">选取</span>页面可视化搭建工具支持的前端框架. 如: 页面可视化搭建工具只支持基于 vue 的页面, 那页面组件化的前端框架只能<span style="color: black;">选取</span> vue.</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">然则</span>前端技术团队<span style="color: black;">选择</span>的前端框架, <span style="color: black;">通常</span>已用于支持现有业务, 并沉淀了<span style="color: black;">必定</span>数量的技术组件和业务组件. <span style="color: black;">倘若</span>需要针对页面可视化搭建工具进行前端框架的切换, 成本将会很大.</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">因此</span>理想的页面可视化搭建工具, 应该和页面的前端框架解偶, 如下图所示. 技术团队在某前端框架中沉淀的技术组件和业务组件, 可在页面可视化搭建工具的页面中复用.</span></p><img src="https://mmbiz.qpic.cn/mmbiz_png/meG6Vo0MeviarQXnEQ2u7rXibzC9old6vqq4gTCv9F6bYZgmlqcuj1DVeAzXSJIj7LcJh5sPKCHQAED4CTJIYjrQ/640?wx_fmt=png&tp=webp&wxfrom=5&wx_lazy=1&wx_co=1" style="width: 50%; margin-bottom: 20px;">

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">当然, 前端业务已<span style="color: black;">选择</span>了某前端框架, <span style="color: black;">研发</span>专门支持该前端框架的页面可视化搭建工具, <span style="color: black;">亦</span>是<span style="color: black;">有效</span>实现<span style="color: black;">目的</span>的<span style="color: black;">选取</span>.</span></p><span style="color: black;">页面模板</span>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">页面构建是组件化前端源码生成页面资源的必要环节: 在<span style="color: black;">研发</span>时需要进行<span style="color: black;">研发</span>构建来进行页面调试; 在可视化编辑后可能需要重新构建来生成预览页面; 在发布前需要进行生产构建.</span></p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">组件和模板的编写方式需遵循较简单的编写约定, 避免<span style="color: black;">研发</span>人员难上手和写起来不舒服.</span></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">自定义模板和组件和在<span style="color: black;">研发</span>模式下进行调试和测试.</p>页面可视化搭建工具必然会对页面模板和页面组件的编码方式进行限定. 这<span style="color: black;">需求</span>就页面可视化工具在页面模板和页面组件上的约束较少, 减少对前端框架代码组织方式的入侵点.
