Uni 直播 uniLiveShow 是基于 uni-app 开发的多端小视频 /聊天 /直播室实例项目，之前就有使用vue+uniapp 仿微信即时聊天，这次直播项目用到了 vue+Nvue+uniapp+vuex+swiper 等技术实现。并且小视频及直播页面均可类似抖音一样上下滑动切换，有播放、暂停、点赞、评论、商品等功能。

import Vue from 'vue'
import App from './App'
// >>>引入 css
import './assets/fonts/iconfont.css'
import './assets/css/reset.css'
import './assets/css/layout.css'
// >>>引入状态管理
import store from './store'
Vue.prototype.$store = store
// >>>引入公共组件
import headerBar from './components/header/header.vue'
import tabBar from './components/tabbar/tabbar.vue'
Vue.component('header-bar', headerBar)
Vue.component('tab-bar', tabBar)
// >>>引入 uniPop 弹窗组件
import uniPop from './components/uniPop/uniPop.vue'
Vue.component('uni-pop', uniPop)
Vue.config.productionTip = false
App.mpType = 'app'
const app = new Vue({
...App
})
app.$mount()
项目中的聊天部分，可参看这篇：uniapp 聊天室 App|vue+uniapp 仿微信聊天界面|仿微信朋友圈
uni-app+nvue 技术实现仿抖音界面滑动效果，且有点赞、评论及商品等功能，可以单击、双击判断。

如果在开发时遇到 video 不能覆盖的问题，可改 vue 页面为 nvue，不过需要注意 nvue 页面 css 写法。 最后分享个：react+react-redux 仿微信 web 版聊天|网页版聊天室
