随着生活品质的提高及人们观念的改变，短视频/直播获得愈来愈多新一代人的喜爱，2021又是一个直播元年。

今天给大家分享的是vue3.0实战小视频+直播+聊天项目。基于vue3.0.5+vuex+vant3+v3popup等技术架构的一款移动端仿抖音|微信直播聊天互动项目。

短视频页支持滑屏切换视频、点赞/评论/分享、链接查看、小商品等功能。

运用技术

• 编辑器：VScode
• 构建工具：vite.js
• 使用技术：Vue3.x+Vuex4.x+Vue-Router4
• 组件库：Vant^3.0.4 (有赞移动端vue3组件库)
• 弹层组件：V3Popup（基于vue3自定义弹层组件）
• 字体图标：阿里iconfont图标库
• 导航栏+标签栏：基于vue3自定义navbar/tabbar组件

整个项目采用分层式目录结构，非常简洁清晰，运用了vue3最新组合式语法编码开发。

vite项目配置

/**
 * Vite2项目配置
 */

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')
  }
}

vue3分离公共组件

新建一个plugin.js用来导入一些常用的公共组件。

/**
 * 引入公共组件
 */

// 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)
}

vue3短视频/直播实现

项目中的短视频和直播模板都使用到了vant3组件库中的swipe来实现滑屏切换。

整体分为顶部、视频区、底部工具栏三大模块。

如上图：滑动切换还是很流畅的。如果怕卡顿，可以设置lazy-render来延迟加载下一页模板数据。

项目中的所有弹窗功能均是v3popup组件来实现。支持自定义插槽来插入自定义内容模块。
