2020年快手获得了春晚冠名合作，今年则是抖音成为春晚独家红包互动合作伙伴。
春晚的赞助商已逐步由传统行业转向互联网企业。社交短视频、直播已经成为很多新一代人的互动交流方式，随着5G技术的日趋成熟，不久的将来视频直播更加的受欢迎！
vue3.0-douyin 基于
vite2+vue3.0+vuex4+vant3+v3popup技术开发的一款仿抖音/快手短视频直播聊天项目。实现了短视频滑动效果、聊天评论/弹幕/送礼物等功能。
框架技术
- 技术框架：vue3.0+vue-router+vuex4
- 组件库：vant3.x (有赞移动端vue3组件库)
- 弹层组件：v3popup (移动端vue3弹框组件)
- 字体图标：阿里iconfont图标
- 导航条+Tab栏：自定义顶部导航/底部标签栏组件
目录结构
vue3.0自定义mobile弹框组件
V3Popup 一款多功能的vue3.x移动端弹框组件。支持组件式+函数式调用方式，超过6+弹框类型、5+动画效果及20+自定义配置参数。
如果对其实现方式感兴趣，可以去看看之前的这篇分享文章。
vite.config.js项目配置
基于vite脚手架构建工具创建的项目，会有一个vite.config.js配置文件。可进行一些简单的环境及路径别名配置。
import vue from '@vitejs/plugin-vue'import path from 'path'/** * @type {import('vite').UserConfig} */export default { plugins: [vue()], build: { // 基本目录 // base: '/', /** * 输出文件目录 * @default dist（默认） */ // outDir: 'target', }, // 环境配置 server: { // 自定义接口 port: 3000, // 是否自动浏览器打开 open: false, // 是否开启https https: false, // 服务端渲染 ssr: false, // 代理配置 proxy: { // ... } }, // 设置路径别名 alias: { '@': path.resolve(__dirname, './src'), '@components': path.resolve(__dirname, './src/components'), '@views': path.resolve(__dirname, './src/views') }}
引入公共组件
新建一个plugins.js文件，用来引入一些常用的公共组件。
// 引入Vant3.x组件库import Vant from 'vant'import 'vant/lib/index.css'// 引入Vue3.x移动端弹层组件import V3Popup from '@components/v3popup'import NavBar from '@components/navBar.vue'import TabBar from '@components/tabBar.vue'import Utils from './utils'import Storage from './storage'const Plugins = (app) => { app.use(Vant) app.use(V3Popup) // 注册公用组件 app.component('navbar', NavBar) app.component('tabbar', TabBar) app.provide('utils', Utils) app.provide('storage', Storage)}
首页布局模板
首页分为顶部navbar+视频区+底部tabbar三个部分。其中底部及底部组件开启transparent fixed属性，会镂空固定在视频区之上。

vue3.0短视频+直播模块
使用vant3中的swipe组件实现小视频_左右上下滑动_切换效果。
上下滑动切换视频，并且停止小视频播放。
// 垂直切换视频事件
const handleSwipeVertical = (index) => {
if(data.activeNav == 0) {
// 附近页
data.activeOneIdx = index
}else if(data.activeNav == 1) {
// 关注页
data.activeTwoIdx = index
}else if(data.activeNav == 2) {
// 推荐页
data.activeThreeIdx = index
}
vdTimer.value && clearInterval(vdTimer.value)
data.vdProgress = 0
data.isPlay = false
let video = getVideoContext()
if(!video) return
video.pause()
// 重新开始
video.currentTime = 0
data.activeSwipeIndex = index
// 自动播放下一个
handlePlay()
}
控制点击视频区域播放/暂停功能。
// 视频点击事件（判断单/双击）
const handleVideoClicked = () => {
console.log('触发视频点击事件...')
tapTimer.value && clearTimeout(tapTimer.value)
data.clickNum++
tapTimer.value = setTimeout(() => {
if(data.clickNum >= 2) {
console.log('双击事件')
}else {
console.log('单击事件')
if(data.isPlay) {
handlePause()
}else {
handlePlay()
}
}
data.clickNum = 0
}, 300)
}
// 播放
const handlePlay = () => {
console.log('播放视频...')
let video = getVideoContext()
if(!video) return
video.play()
data.isPlay = true
// 设置进度条
vdTimer.value = setInterval(() => {
handleProgress()
}, 16)
}
// 暂停
const handlePause = () => {
console.log('暂停视频...')
let video = getVideoContext()
if(!video) return
video.pause()
data.isPlay = false
vdTimer.value && clearInterval(vdTimer.value)
}
视频区底部有一条迷你进度条展示。通过小视频时长和当前播放时间转换为百分比，然后通过css3 transition控制动画效果。
// 播放进度条
const handleProgress = () => {
let video = getVideoContext()
if(!video) return
let curTime = video.currentTime.toFixed(1)
let duration = video.duration.toFixed(1)
data.vdProgress = parseInt((curTime / duration).toFixed(2) * 100)
}
送礼物/充值模板使用的是v3popup组件来实现。
