基於vue3.0仿抖音滑動小視頻|vue3+vant3短視頻/直播實例

項目概述

Vue3DouYin短視頻 基於vite2+vue3.x+vant3+vuex4+v3popup等技術開發的高仿抖音app|微信直播實例項目。實現上下左右滑動切換小視頻、點贊/評論、聊天、送禮物/彈幕/紅包等功能。

有贊移動端vue3組件庫中的swipe組件實現小視頻滑動切換效果。

實現小視頻播放/暫停、點贊/評論等功能。

運用技術

• 編碼器：Vscode
• 技術框架：vue3.x+vuex4.x+vue-router4
• 組件庫：vant^3.0.4 (有贊移動端vue3.x組件庫)
• 彈層組件：v3popup（vue3自定義彈出框組件）
• 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
• 構建工具：vite2 (新一代web構建工具)

項目結構目錄

vue3全局自定義手機端彈框

vue3-douyin項目中的所有彈窗場景均是自定義彈框組件實現。

至於彈框實現，這裏不作介紹，之前有過一篇歷史分享文章。

vue3.0自定義組件系列：vue3全局mobile彈窗組件v3popup

vue3主入口配置

在main.js中配置一些路由/狀態管理、公共組件引入。

import { createApp } from 'vue'
import App from './App.vue'

// 引入Router及Vuex
import router from './router'
import store from './store'

// 引入公用組件
import Plugins from './plugins'

// 引入Js
import '@/assets/js/fontSize'

// 引入公用樣式
import '@/assets/fonts/iconfont.css'
import '@/assets/css/reset.css'
import '@/assets/css/layout.css'

const app = createApp(App)

app.use(router)
app.use(store)
app.use(Plugins)

app.mount('#app')

vite.config.js配置

使用vite構建工具搭建的項目，會自動生成一個vite.config.js配置文件。進行一些簡單的環境及路徑別名配置。

/**
 * 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')
  }
}

vue3小視頻功能實現

小視頻頁面總體分爲底部導航、視頻信息區、底部tab三個部分。

另外底部迷你進度條功能是使用視頻時長、當前播放進度轉換爲百分比，加上css3來控制。每一次切換視頻都會重置進度條狀態。

直播頁面仿製了微信直播界面，新增彈幕功能，設置了三條航道滾動顯示。
