vue3.0-douyin 基于vue3.x开发仿抖音app界面小视频+直播聊天实例。

基于Vue3框架技术搭建一款仿抖音APP界面小视频+直播实战案例。运用到了vite2+vue3.0.5+vuex4+vue-router@4+vant3+v3popup等技术，实现了短视频滑动切换、暂停/迷你进度条、聊天评论/弹幕/送礼物等功能。

  

技术框架

• 技术/编码：vscode / vue3.0+vue-router+vuex4
• UI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

项目结构

采用标准的vue3分层目录结构，让项目结构更加清晰。

所有的页面模板及逻辑部分统一使用vue3.x最新语法来编码。

vue3手机端弹框组件

整个项目所用到的弹框功能，都是使用vue3.0自定义组件实现。

v3-popup 一款轻量级的移动端vue3弹框组件。集合了msg、alert、dialog、modal、actionSheet、toast等多种弹框类型。支持超过20+中参数自定义配置。

vite2配置文件

使用vite构建vue3项目后，会有一个vite.config.js配置文件。用来进行一些项目配置。

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公共组件配置

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)
}

export default Plugins

然后在main.js中全局引入注册即可。

// 引入公用组件
import Plugins from './plugins'

const app = createApp(App)
app.use(Plugins)

// ...

vue3注册表单验证 | 60s倒计时

vue3.0中实现表单模板注册功能及倒计时控制。getCurrentInstance来获取上下文操作store或router。

vue3小视频 | 直播模块

项目中小视频及直播页面使用了vant3组件库中的swipe轮播组件实现滑动切换效果。

开启lazy-render功能，可延迟渲染内容，让滑动效果更加流畅。
