Vue3.0网页版聊天|Vue3.x+ElementPlus仿微信/QQ界面|vue3聊天实例
一、项目简介
基于vue3.x+vuex+vue-router+element-plus+v3layer+v3scroll等技术构建的仿微信web桌面端聊天实战项目Vue3-Webchat。基本上实现发送消息+emoj表情、图片/视频查看、链接预览、粘贴截图/拖拽发送图片、红包/朋友圈等功能。
二、使用技术
- 编码器:Vscode
- 技术框架:Vue3.0.5+Vuex4+VueRouter@4
- UI组件库:Element-Plus (饿了么桌面端vue3组件库)
- 弹窗组件:V3Layer(基于vue3.x自定义对话框组件)
- 滚动条组件:V3Scroll(基于vue3.x自定义虚拟美化滚动条组件)
- 字体图标:阿里iconfont图标库
三、项目结构目录
◆ 一览效果
◆ vue3.x封装自定义弹窗组件
为了整体效果一致性,项目中用到的所有弹窗功能均是自定义组件v3layer来实现。
V3Layer 基于vue3.0开发的pc端自定义弹窗组件,支持拖拽(自定义拖拽区)、缩放、最大化、全屏、置顶弹框等功能。
由于之前有过一篇详细的介绍分享,感兴趣的话可以去看下哈。

其实v3layer弹窗是在原先的vue2版本中演变而来,专门为vue3项目而开发的,并且在功能及效果上和v2版的保持一致。

◆ vue3.x自定义美化模拟滚动条
为了使得项目中页面滚动条更加精致,这里采用了自定义模拟滚动条vscroll组件来替代原生滚动条。
V3Scroll 基于vue3.0开发的小巧模拟滚动条组件。支持自定义滚动条大小、颜色、层级及自动隐藏等功能。
并且支持实时监测DOM尺寸改变来动态更新滚动条。

◆ vue3.x聊天主面板
项目整体分为右上按钮、侧边栏、中间区、主体内容区三个模块。
<div :class="['vui__wrapper', store.state.isWinMaximize&&'maximize']"> <div class="vui__board flexbox"> <div class="flex1 flexbox"> <!-- 顶部按钮(最大、最小、关闭) --> <WinBar v-if="!route.meta.hideWinBar" /> <!-- 侧边栏 --> <SideBar v-if="!route.meta.hideSideBar" class="nt__sidebar flexbox flex-col" /> <!-- 中间栏 --> <Middle v-show="!route.meta.hideMiddle" /> <!-- 主内容区 --> <router-view class="nt__mainbox flex1 flexbox flex-col"></router-view> </div> </div> </div>
◆ 引入|注册公共组件
// 引入饿了么vue3组件库 import ElementPlus from 'element-plus' import 'element-plus/lib/theme-chalk/index.css' // 引入vue3.x弹窗组件 import V3Layer from '../components/v3layer' // 引入vue3.x滚动条组件 import V3Scroll from '@components/v3scroll' // 引入公共组件 import WinBar from '../layouts/winbar.vue' import SideBar from '../layouts/sidebar' import Middle from '../layouts/middle' import Utils from './utils' const Plugins = app => { app.use(ElementPlus) app.use(V3Layer) app.use(V3Scroll) // 注册公共组件 app.component('WinBar', WinBar) app.component('SideBar', SideBar) app.component('Middle', Middle) app.provide('utils', Utils) }
项目中背景整体采用虚化毛玻璃效果。通过 svg filter 来实现。
<!-- //虚化背景(毛玻璃) --> <div class="vui__bgblur"> <svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="100%" height="100%" class="blur-svg" viewBox="0 0 1920 875" preserveAspectRatio="none"> <filter id="blur_mkvvpnf"><feGaussianBlur in="SourceGraphic" stdDeviation="50"></feGaussianBlur></filter> <image :xlink:href="store.state.skin" x="0" y="0" width="100%" height="100%" externalResourcesRequired="true" xmlns:xlink="http://www.w3.org/1999/xlink" style="filter:url(#blur_mkvvpnf)" preserveAspectRatio="none"></image> </svg> <div class="blur-cover"></div> </div>
◆ vue3.x表单验证/登录状态拦截
vue3中实现表单验证+60s倒计时操作。
<script> import { reactive, toRefs, inject, getCurrentInstance } from 'vue' export default { components: {}, setup() { const { ctx } = getCurrentInstance() const v3layer = inject('v3layer') const utils = inject('utils') const formObj = reactive({}) const data = reactive({ vcodeText: '获取验证码', disabled: false, time: 0, }) const VTips = (content) => { v3layer({ content: content, layerStyle: 'background:#ff5151;color:#fff;', time: 2 }) } const handleSubmit = () => { if(!formObj.tel){ VTips('手机号不能为空!') }else if(!utils.checkTel(formObj.tel)){ VTips('手机号格式不正确!') }else if(!formObj.pwd){ VTips('密码不能为空!') }else if(!formObj.vcode){ VTips('验证码不能为空!') }else{ ctx.$store.commit('SET_TOKEN', utils.setToken()); ctx.$store.commit('SET_USER', formObj.tel); // ... } } // 60s倒计时 const handleVcode = () => { if(!formObj.tel) { VTips('手机号不能为空!') }else if(!utils.checkTel(formObj.tel)) { VTips('手机号格式不正确!') }else { data.time = 60 data.disabled = true countDown() } } const countDown = () => { if(data.time > 0) { data.vcodeText = '获取验证码('+ data.time +')' data.time-- setTimeout(countDown, 1000) }else{ data.vcodeText = '获取验证码' data.time = 0 data.disabled = false } } return { formObj, ...toRefs(data), handleSubmit, handleVcode } } } </script>
vue3路由钩子实现全局登录状态拦截判断。
import { createRouter, createWebHistory } from 'vue-router' import store from '../store' import V3Layer from '@components/v3layer' const routesLS = [ // 登录|注册 { name: 'login', path: '/login', component: () => import('../views/auth/login.vue'), meta: { hideWinBar: true, hideSideBar: true, hideMiddle: true } }, // ... ] const router = createRouter({ history: createWebHistory(), routes: routesLS, }) // 全局钩子拦截登录状态 router.beforeEach((to, from, next) => { const token = store.state.token // 判断当前路由地址是否需要登录权限 if(to.meta.requireAuth) { if(token) { next() }else { // 未登录授权 V3Layer({ content: '还未登录授权!', position: 'top', time: 2, onEnd: () => { next({ path: '/login' }) } }) } }else { next() } })
◆ vue3.x聊天模块
聊天编辑器模块继续采用分离公共调用方式。支持多行文本、文字+emoj表情混排、光标处插入表情、粘贴截图发送等功能。
