Vue3.0聊天室|vue3+vant3仿微信聊天实例|vue3.x仿微信app界面

一、项目简介

基于Vue3.0+Vant3.x+Vuex4.x+Vue-router4+V3Popup等技术开发实现的仿微信手机App聊天实例项目Vue3-Chatroom。实现了发送图文表情消息/gif图、图片/视频预览、网址查看、下拉刷新功能、红包/朋友圈等功能。

二、技术选型

• 编辑器：VScode/Sublime
• 使用技术：Vue3.x+Vuex4.x+Vue-Router4
• UI组件库：Vant-UI3.x (有赞移动端Vue3组件库)
• 弹层组件：V3Popup（基于vue3.0封装自定义弹出层组件）
• iconfont图标：阿里字体图标库
• 自定义顶部导航栏+底部tabBar

◆ 项目结构

◆ Vue3自定义顶部Navbar+底部Tabbar

项目中顶部导航条和底部tabbar组件均是在之前vue2版的基础上开发的vue3版。

◆ Vue3自定义弹层组件

项目中使用到的弹框场景，均是最新开发的vue3.0自定义弹框组件v3popup来实现的。

v3popup 一款汇集多种弹框类型及动画效果的vue3.x弹框组件。开发灵感来源于之前的vue2版，并在功能及效果上保持一致性。

如果大家对具体的实现感兴趣的话，可以去看看之前的这篇文章。

◆ vue.config.js配置

/**
 * Vue3基础配置文件
 */

const path = require(\'path\')

module.exports = {
    // 基本路径
    // publicPath: \'/\',

    // 输出文件目录
    // outputDir: \'dist\',

    // assetsDir: \'\',

    // 环境配置
    devServer: {
        // host: \'localhost\',
        // port: 8080,
        // 是否开启https
        https: false,
        // 编译完是否打开网页
        open: false,
        
        // 代理配置
        // proxy: {
        //     \'^/api\': {
        //         target: \'<url>\',
        //         ws: true,
        //         changeOrigin: true
        //     },
        //     \'^/foo\': {
        //         target: \'<other_url>\'
        //     }
        // }
    },

    // webpack配置
    chainWebpack: config => {
        // 配置路径别名
        config.resolve.alias
            .set(\'@\', path.join(__dirname, \'src\'))
            .set(\'@assets\', path.join(__dirname, \'src/assets\'))
            .set(\'@components\', path.join(__dirname, \'src/components\'))
            .set(\'@views\', path.join(__dirname, \'src/views\'))
    }
}

◆ Vue3.0主入口页面

在main.js中配置一些状态管理、地址路由，引入一些js和公共组件。

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

// 引入vuex和地址路由
import store from \'./store\'
import router from \'./router\'

// 引入js
import \'@assets/js/fontSize\'

// 引入公共组件
import Plugins from \'./plugins\'

const app = createApp(App)

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

app.mount(\'#app\')

◆ Vuex + 表单登录验证

vue3中状态管理及表单验证操作。

import { createStore } from \'vuex\'

export default createStore({
    state: {
        user: localStorage.getItem(\'user\') || null,
        token: localStorage.getItem(\'token\') || null
    },
    mutations: {
        SET_USER(state, data) {
            localStorage.setItem(\'user\', data)
            state.user = data
        },
        SET_TOKEN(state, data) {
            localStorage.setItem(\'token\', data)
            state.token = data
        },
        LOGOUT(state) {
            localStorage.removeItem(\'user\')
            localStorage.removeItem(\'token\')
            state.user = null
            state.token = null
        }
    },
    getters: {},
    actions: {}
})

<script>
import { reactive, inject, getCurrentInstance } from \'vue\'
export default {
    components: {},
    setup() {
        const { ctx } = getCurrentInstance()

        const v3popup = inject(\'v3popup\')
        const utils = inject(\'utils\')
        const formObj = reactive({})

        // ...

        const handleSubmit = () => {
            if(!formObj.tel){
                Snackbar(\'手机号不能为空！\')
            }else if(!utils.checkTel(formObj.tel)){
                Snackbar(\'手机号格式不正确！\')
            }else if(!formObj.pwd){
                Snackbar(\'密码不能为空！\')
            }else{
                ctx.$store.commit(\'SET_TOKEN\', utils.setToken());
                ctx.$store.commit(\'SET_USER\', formObj.tel);

                // ...
            }
        }

        return {
            formObj,
            handleSubmit
        }
    }
}
</script>

◆ 仿微信朋友圈透明导航实现

vue3通过在onMounted中监听scroll事件来控制顶部导航透明显示。

  

<!-- //朋友圈模板 -->
<template>
    <div>
        <header-bar :bgcolor="headerBg" transparent zIndex="1010">
            <template #backIco><i class="iconfont icon-arrL"></i></template>
            <template v-slot:right><div @click="isShowPublish=true"><i class="iconfont icon-tianjia"></i></div></template>
        </header-bar>

        <div class="vui__scrollview flex1" ref="scrollview">
            ...
        </div>
    </div>
</template>

<script>
import { onMounted, onBeforeUnmount, ref, reactive, toRefs, inject } from \'vue\'
import { ImagePreview } from \'vant\'

export default {
    components: {},
    setup() {
        const scrollview = ref(null)

        const data = reactive({
            headerBg: \'transparent\',
            // ...
        })

        onMounted(() => {
            scrollview.value.addEventListener(\'scroll\', handleScroll)
        })

        onBeforeUnmount(() => {
            scrollview.value.removeEventListener(\'scroll\', handleScroll)
        })

        // 页面滚动处理
        const handleScroll = (e) => {
            if(e.target.scrollTop > 160) {
                data.headerBg = \'linear-gradient(to right, #00d2ee, #00e077)\'
            }else {
                data.headerBg = \'transparent\';
            }
        }

        // ...

        return {
            ...toRefs(data),
            scrollview,
            
            // ...
        }
    }
}
</script>
