可视化搭建移动端店铺解决方案

前言

经过许久的深思熟虑与探索,同时也借鉴了行业内不错的产品(如:有赞H5-Dooring等),但跟列举的产品还是有区别的(先卖个关子,后面再讲有哪些区别)。其实这种功能在零售系统(目前我所在公司是零售行业的领头羊)和电商系统应该很常见,很多应用场景都会用到,像产品营销页面、企业/个人微官网、H5活动页面等移动端页面,通过可视化配置快速搭建H5页面,且提供丰富的页面组件,更方便的为使用者搭建更强大的H5页面。

PC端界面如下:

移动端(H5和小程序)界面如下:

技术方案

PC端 React 技术栈,移动端 UniApp 跨平台框架,功能的设计结构图如下:

        compiler: 'PageSetting',
        pagename: '页面标题',
        selectIndex: 0,

数据

前面说到与列举的产品有哪些区别,区别在于PC端与移动端的数据交互,它们都是通过 iframe 嵌套 H5 的页面,通过 postmessage API 来做数据交互,而是我没有这样做,原因是项目特别紧,加上人员分配问题,所以采用数据定义模式。

通过上面的设计结构图可以看出PC端最后会生成一份 schema 数据存储服务端,移动端从服务端获取到 schema 数据进行解析。数据格式如下:

// 图片广告
{
    component: 'ImageTextAd',
    options: {
        template: 'image', // image:一行一个 carousel:轮播海报 slide:大图横向滑动 zone:绘制热区

拖拽

拖拽依赖第三方库react-dnd,提供的Hooks Api特别方便,上面的设计结构图 Component组件(DragSource) 和 Preview组件(DropTarget) 用到了拖拽,Preview组件不仅要支持上下拖拽,而且需要配合Compiler组件联动。

总结

开发耗费时间比较长的地方是怎么设计与移动端同步数据和拖拽功能,最后还是迎刃而解。如果大家有什么疑问可以交流一下🤝
