介绍
vue3Douyin 是一款基于vite2构建工具搭建开发的vue3仿制抖音实战项目。使用了vue3.0+vuex+vant3+v3popup等技术编码开发，实现小视频上下滑动切换、点赞/评论/分享等功能。

小视频页有附近/关注/推荐三大模块，可以实现左右及上下滑动切换效果。

如上图：这个是原型设计，最终效果是下面这些展示图片。

实现技术

构建工具：Vite.js
编辑器：Vscode
MVVM框架：Vue^3.0.5
状态管理：Vuex^4.0.0-rc.2
页面路由：Vue-Router^4.0.3
UI组件库：Vant^3.0.4 (有赞手机端vue3组件库)
弹框组件：v3popup（基于vue3自定义手机端弹出层组件）
字体图标：阿里iconfont图标
顶部条+底部栏：基于vue3自定义navbar/tabbar组件

另外项目中所有的弹窗功能，均是vue3自定义移动端弹框v3popup组件来实现。
