一、项目概述

uniapp-ttlive 一款基于uni-app+uview-ui+vue.js+uapopup等技术混合开发的多端仿制抖音短视频/直播/聊天项目。支持全屏沉浸式、上下滑动切换视频等功能。

二、预览效果

如下图:在h5、小程序、APP端编译效果

三、编码技术

  • 编码器/技术:HbuilderX3.1.21+Uniapp+Nvue+Vuex+Uapopup
  • UI组件库:uView-ui / uni-ui
  • 矢量图标库:iconfont字体图标
  • 弹窗组件:UApopup 基于uni-app封装跨端弹窗组件
  • 自定义导航条+底部菜单栏
  • 编译支持:H5+小程序+APP端

四、功能特性

✅ 支持全屏沉浸式透明模式
✅ 顺滑的上下滑动体验
✅ 迷你时间进度条
✅ 自定义组件支持Nvue页面

五、目录结构/编译

项目中使用的组件库是uview-ui,多平台快速开发UI框架。

main.js配置

import Vue from 'vue'
import App from './App'

import uView from 'uview-ui'
Vue.use(uView)

import API from '@/common/request'
Vue.prototype.$api = API

// 引入状态管理
import Store from './store'
Vue.prototype.$store = Store

Vue.config.productionTip = false
App.mpType = 'app'

// #ifdef APP-PLUS
plus.navigator.closeSplashscreen()
// #endif

const app = new Vue({
    ...App
})
app.$mount()

考虑到Nvue页面不支持prototype原型全局挂载,改为使用globalData来控制。
