Vue3.0短视频+直播|vue3+vite2+vant3仿抖音界面|vue3.x小视频实例

基于vue3.0构建移动端仿抖音/快手短视频+直播实战项目Vue3-DouYin。

5G时代已来，短视频也越来越成为新一代年轻人的娱乐方式，在这个特殊之年，又将再一次成为新年俗！

基于vue3.x+vite2+vuex4+vue-router+vant3+v3popup等技术搭建开发仿抖音App界面小视频/直播/聊天实例项目。实现短视频上下左右滑动切换、点赞/评论/聊天/红包及送礼物等功能。

一、运用技术

• 编码器：VScode/Notepad++
• 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

二、项目目录结构

◆ 效果预览

◆ vue3.x自定义顶部导航+标签栏

项目中所有顶部导航及底部tabbar均是使用vue3自定义组件来实现效果，支持自定义插槽内容。

<navbar :back="false" bgcolor="transparent" transparent>
    <template v-slot:title>
        <div class="navbar__tab">
            ...
        </div>
    </template>
    <template v-slot:right><div><i class="iconfont icon-search"></i></div></template>
</navbar>

<tabbar
    bgcolor="linear-gradient(to bottom, transparent, rgba(0,0,0,.6))"
    color="rgba(255,255,255,.6)"
    activeColor="#fff"
    fixed
/>

◆ vue3.x全局弹出层组件

项目中所有的弹框应用场景均是之前开发的一款vue3自定义组件v3popup来实现功能。

vue3版的自定义弹框组件，拥有20+种自定义参数配置，多种弹框类型及动画效果。

◆ vite.config.js配置文件

一些简单的vite2项目配置，可进行一些常用环境及alias路径别名设置。

/**
 * 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')
  }
}

◆ 引入公共组件

让项目代码更加整洁，在plugins.js中配置一些公共组件，然后在main.js中引入即可。

/**
 * 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)
}

export default Plugins

◆ vue3.x表单验证+60s倒计时

◆ vue3.x实现小视频功能

小视频页面使用了有赞组件库中的swipe组件来实现滑动切换，开启lazy-render让滑动更加流畅。

◆ vue3.x弹幕功能简单实现

直播页面在小视频页面功能基础上新增弹幕，滚动消息区、送礼物、充值弹窗等功能。

弹幕功能的简单实现，共有3条滚动路线。

const data = reactive({
    // ...

    // 弹幕队列
    idx: 2,
    dmLs: [
        ...
    ],
    // 正在执行的弹幕队列
    dmActiveLs: []
})

onMounted(() => {
    // ...

    // 装载弹幕
    setInterval(() => {
        starDanMu()
    }, 1500)
})

const starDanMu = () => {
    let query = null
    if(!query) {
        query = data.dmLs.shift()
    }
    if(query) {
        query.row = data.idx
        data.idx = (data.idx % 3 + 1)
        data.dmActiveLs.push(query)
    }
}

<div class="lv__wrap-danmu">
    <div class="danmu__bx">
        <div class="danmu__ls" v-for="item in dmActiveLs" :key="item.id" :data-row="item.row" @animationend="dmAnimationEnd">
            <div class="item">
                <img class="avatar" :src="item.avatar" />
                <p class="name">{{item.name}}</p><p class="desc">{{item.desc}}</p>
            </div>
        </div>
    </div>
</div>

OK，以上就是使用vue3.x+vite2开发仿抖音小视频/直播的一些分享，希望对大家有些帮助哈~~ ✍
