很早之前就有使用html5技术开发过一个web版仿微信、微博聊天，后来想着用vue技术开发一版，后面由于各种事情，一直没能落定。最近有些空闲就使用vue开发了一个vueWechat聊天室IM项目。基于Vue2.5.6+Vuex+vue-router+vue-gemini-scrollbar+swiper+elementUI等技术开发，实现了发送消息、表情(动图)，图片、视频预览，仿微信右键菜单、网页截图可直接粘贴至编辑框发送。

vue技术选型

MVVM框架：Vue2.5.6
状态管理：Vuex
页面路由：Vue-router
iconfont图标：阿里巴巴字体图标库
自定义滚动条：vue-gemini-scrollbar
弹窗组件：element-ui（饿了么前端UI库）
环境配置：node.js + cnpm + webpack
高德地图：vue-amap
图片预览：vue-photo-preview
