Vue3.0短視頻+直播|vue3+vite2+vant3仿抖音界面|vue3.x小視頻實例

基於vue3.0構建移動端仿抖音/快手短視頻+直播實戰項目Vue3-DouYin。

5G時代已來，短視頻也愈來愈成爲新一代年輕人的娛樂方式，在這個特殊之年，又將再一次成爲新年俗！

基於vue3.x+vite2+vuex4+vue-router+vant3+v3popup等技術搭建開發仿抖音App界面小視頻/直播/聊天實例項目。實現短視頻上下左右滑動切換、點贊/評論/聊天/紅包及送禮物等功能。

1、運用技術

• 編碼器：VScode/Notepad++
• 使用技術：Vue3.x+Vuex4.x+Vue-Router4
• 組件庫：Vant^3.0.4 (有贊移動端vue3組件庫)
• 彈層組件：V3Popup（基於vue3自定義彈層組件）
• 字體圖標：阿里iconfont圖標庫
• 導航欄+標籤欄：基於vue3自定義navbar/tabbar組件

2、項目目錄結構

◆ 效果預覽

◆ vue3.x自定義頂部導航+標籤欄

項目中全部頂部導航及底部tabbar均是使用vue3自定義組件來實現效果，支持自定義插槽內容。

<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全局彈出層組件

項目中全部的彈框應用場景均是以前開發的一款vue3自定義組件v3popup來實現功能。

vue3版的自定義彈框組件，擁有20+種自定義參數配置，多種彈框類型及動畫效果。

◆ vite.config.js配置文件

一些簡單的vite2項目配置，可進行一些經常使用環境及alias路徑別名設置。

/**
 * Vite2項目配置
 */

import vue from '@vitejs/plugin-vue'

import path from 'path'

/**
 * @type {import('vite').UserConfig}
 */
export default {
  plugins: [vue()],

  build: {
    // 基本目錄
    // base: '/',

    /**
     * 輸出文件目錄
     * @default dist（默認）
     */
    // outDir: 'target',
  },

  // 環境配置
  server: {
    // 自定義接口
    port: 3000,

    // 是否自動瀏覽器打開
    open: false,

    // 是否開啓https
    https: false,

    // 服務端渲染
    ssr: false,

    // 代理配置
    proxy: {
        // ...
    }
  },

  // 設置路徑別名
  alias: {
    '@': path.resolve(__dirname, './src'),
    '@components': path.resolve(__dirname, './src/components'),
    '@views': path.resolve(__dirname, './src/views')
  }
}

◆ 引入公共組件

讓項目代碼更加整潔，在plugins.js中配置一些公共組件，而後在main.js中引入便可。

/**
 * 引入公共組件
 */

// 引入Vant3.x組件庫
import Vant from 'vant'
import 'vant/lib/index.css'

// 引入Vue3.x移動端彈層組件
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)

    // 註冊公用組件
    app.component('navbar', NavBar)
    app.component('tabbar', TabBar)

    app.provide('utils', Utils)
    app.provide('storage', Storage)
}

export default Plugins

◆ vue3.x實現小視頻功能

小視頻頁面使用了有贊組件庫中的swipe組件來實現滑動切換，開啓lazy-render讓滑動更加流暢。

至於項目中的聊天模塊就不詳細介紹了，以前有分享過一篇vue3.0開發移動端聊天實例項目，感興趣的能夠去看看哈~~

◆ vue3.x彈幕功能簡單實現

直播頁面在小視頻頁面功能基礎上新增彈幕，滾動消息區、送禮物、充值彈窗等功能。

彈幕功能的簡單實現，共有3條滾動路線。

const data = reactive({
    // ...

    // 彈幕隊列
    idx: 2,
    dmLs: [
        ...
    ],
    // 正在執行的彈幕隊列
    dmActiveLs: []
})

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

    // 裝載彈幕
    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開發仿抖音小視頻/直播的一些分享，但願對你們有些幫助哈~~ ✍🏻😊

最後附上一個vue3網頁版聊天項目
