5G技术愈来愈成熟,手机品牌更新换代快,人们对流媒体的需求也渐渐发生了改变。短视频/直播等沉浸式互动模式逐渐代替了之前的一问一答模式。并且成为新一代人开放表达自我的一种新潮交流方式。 今天给大家分享的是Vue3.0开发仿制抖音小视频|直播|互动聊天实例。
基于vite.js构建的vue3短视频/直播项目,使用了vue3.0+vuex4+vue-router@4+vant3+v3popup等技术搭建开发。 https://www.cnblogs.com/xiaoyan2017/p/14361160.html
vue3DouYin 支持上下滑动切换短视频、点赞/评论、聊天/弹幕/送礼物等功能。
技术栈
- 编码器:Vscode
- MVVM框架:Vue^3.0.5
- 状态管理:Vuex^4.0.0-rc.2
- 页面路由:Vue-Router^4.0.3
- UI组件库:Vant^3.0.4 (有赞手机端vue3组件库)
- 弹框组件:v3popup(基于vue3自定义手机端弹出层组件)
- 字体图标:阿里iconfont图标
- 顶部条+底部栏:基于vue3自定义navbar/tabbar组件
项目结构
Vue3自定义mobile版弹窗组件
项目中使用到的弹框均是vue3自定义组件来实现。
v3popup一款多功能移动端vue3.0自定义弹框组件,支持20+自定义参数配置,拥有多种弹框类型及动画效果。 vue3自定义全局移动端弹框组件
Vue3分离公共组件
新建plugins.js文件,用来导入一些常用的公共组件/插件。
/**
* 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)
}
vite项目配置
使用vite构建工具生成项目,会有一个vite.config.js配置文件。用来进行一些简单的项目配置。
/**
* 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,
// 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短视频/直播实现
项目中的短视频和直播模板,都使用到了swipe组件来实现滑动切换。
小视频页整体分为顶部条、视频区、底部tab三个模块。

swipe轮播组件开启lazy-render会预加载模板,拥有非常流畅的滑动效果。
直播页模仿了微信直播界面,新增了弹幕、送礼物等功能。使用到的弹框功能均是v3popup自定义插槽来实现模板。
