uni-vue3-wchat:基于uni-app+vue3+pinia2高仿微信app谈天模板。
原创基于最新跨端技能uni-app+vue3.x+pinia2+vite4+uv-ui构建三端仿微信app界面谈天实例。实现编辑框多行消息/emoj混合、长按触摸式仿微信语音面板、图片/视频预览、红包/朋友圈等功能。支持编译到H5+小步调端+App端。
整个项目采用vue3 setup语法编码,支持编译到h5+小步调端+APP端。
使用技能
- 编辑器:HbuilderX 4.0.8
- 框架技能:Uniapp+Vue3+Pinia2+Vite4.x
- 组件库:uni-ui+uv-ui
- 弹窗组件:uv3-popup(uniapp+vue3多端自定义弹框组件)
- 导航栏+菜单栏:uv3-navbar+uv3-tabbar组件
- 本地缓存:pinia-plugin-unistorage
- 编译支持:H5+小步调+APP端
uniapp+vue3实现类似微信朋友圈功能。
项目布局
入口main.js设置
- /**
- * 入口文件 main.js
- */
- import { createSSRApp } from 'vue'
- import App from './App'
- // 引入pinia状态管理
- import pinia from '@/pinia'
- export function createApp() {
- const app = createSSRApp(App)
- app.use(pinia)
- return {
- app,
- pinia
- }
- }
复制代码
App.vue设置
采用 vue3 setup 语法开发。
- <script setup>
- import { provide } from 'vue'
- import { onLaunch, onShow, onHide, onPageNotFound } from '@dcloudio/uni-app'
-
- onLaunch(() => {
- console.log('App Launch')
-
- uni.hideTabBar()
- loadSystemInfo()
- })
-
- onShow(() => {
- console.log('App Show')
- })
-
- onHide(() => {
- console.log('App Hide')
- })
-
- onPageNotFound((e) => {
- console.warn('Route Error:', `${e.path}`)
- })
-
- // 获取系统设备信息
- const loadSystemInfo = () => {
- uni.getSystemInfo({
- success: (e) => {
- // 获取手机状态栏高度
- let statusBar = e.statusBarHeight
- let customBar
-
- // #ifndef MP
- customBar = statusBar + (e.platform == 'android' ? 50 : 45)
- // #endif
-
- // #ifdef MP-WEIXIN
- // 获取胶囊按钮的布局位置信息
- let menu = wx.getMenuButtonBoundingClientRect()
- // 导航栏高度 = 胶囊下距离 + 胶囊上距离 - 状态栏高度
- customBar = menu.bottom + menu.top - statusBar
- // #endif
-
- // #ifdef MP-ALIPAY
- customBar = statusBar + e.titleBarHeight
- // #endif
-
- // 由于globalData在vue3 setup存在兼容性问题,改为provide/inject替代方案
- provide('globalData', {
- statusBarH: statusBar,
- customBarH: customBar,
- screenWidth: e.screenWidth,
- screenHeight: e.screenHeight,
- platform: e.platform
- })
- }
- })
- }
