前段时间有分享一篇electron27+react18跨端仿制mateOs桌面系统项目，今天再来分享一款uniapp+vue3跨端仿制抖音短视频+直播商城应用。

https://bbs.huaweicloud.cn/blogs/416211

uniapp-dylive：全新基于uniapp+vue3+pinia+vk-uview等技术跨端仿制抖音/微信直播带货商城项目。支持沉浸式全屏上下滑动短视频直播，Nvue多视频层级覆盖，支持编译到兼容H5+小程序+App端。

使用技术

• 编辑器：HbuilderX 3.98
  
• 框架技术：Uniapp+Vue3+Vite4+Nvue+Pinia
  
• UI组件库：uv-ui+vk-uview
  
• 弹框组件：uaPopup（uniapp封装多端弹框组件）
  
• 自定义组件：uaNavbar+uaTabbar组件
  
• 本地缓存：pinia-plugin-unistorage
  
• 编译支持：H5+小程序+APP端

项目目录结构

整个项目采用vue3 setup语法开发。

main.js配置

/**
 * 入口配置
 */

import { createSSRApp } from 'vue'
import App from './App'

// 引入Pinia状态管理
import Pinia from '@/store'

// 引入vk-uview-ui组件库
import VKuview from '@/uni_modules/vk-uview-ui'

export function createApp() {
	const app = createSSRApp(App)
	app.use(Pinia)
	app.use(VKuview)
	return {
		app,
		Pinia
	}
}

App.vue模板配置

<script>
	export default {
		globalData: {
			// 全局设置状态栏和导航栏高度
			statusBarH: 0,
			customBarH: 0,
			screenWidth: 0,
			screenHeight: 0,
			menuBar: null
		},
		onLaunch: function() {
			console.log('App Launch')
			
			// 隐藏系统tabbar
			uni.hideTabBar()
			this.appInit()
		},
		onShow: function() {
			console.log('App Show')
		},
		onHide: function() {
			console.log('App Hide')
		},
		onPageNotFound: function() {
			console.log('Page Not Found', e.path)
			uni.redirectTo({
				url: '/pages/index/index'
			})
		},
		methods: {
			appInit: function() {
				uni.getSystemInfo({
					success: (e) => {
						// 获取手机状态栏信息
						let statusBar = e.statusBarHeight || 0
						let customBar
						let menuBar
						
						// #ifndef MP
						customBar = statusBar + (e.osName === 'android' ? 50 : 45)
						// #endif
						
						// #ifdef MP-WEIXIN
						// 获取微信小程序胶囊按钮信息
						let menu = wx.getMenuButtonBoundingClientRect()
						// 导航栏高度 = 胶囊下距离 + 胶囊上距离 - 状态栏高度
						customBar = menu.bottom + menu.top - statusBar
						menuBar = menu
						// #endif
						
						// // #ifdef MP-ALIPAY
						customBar = statusBar + e.titleBarHeight
						// #endif
						
						// 兼容nvue写法（H5/小程序/APP/APP-Nvue）
						this.globalData.statusBarH = statusBar
						this.globalData.customBarH = customBar
						this.globalData.screenWidth = e.screenWidth
						this.globalData.screenHeight = e.screenHeight
						this.globalData.menuBar = menuBar
					}
				})
			}
		}
	}
</script>

<style>
	/* #ifndef APP-NVUE */
	@import 'static/fonts/iconfont.css';
	/* #endif */
	.nvueicon {font-family: nvueicon;}
</style>
<style lang="scss">
