前段时间有使用react全家桶技术开发过一个react版手机端聊天室，最近又接着捣鼓pc端聊天室。
一、项目介绍
基于react react-dom react-router-dom redux react-redux webpack2.0 nodejs 等技术混合开发的仿微信web端聊天室reactWebChat项目，实现了聊天记录右键菜单、发送消息、表情(动图)，图片、视频预览，浏览器截图粘贴发送等功能。
二、技术选型 MVVM框架：react / react-dom 状态管理：redux / react-redux 页面路由：react-router-dom 弹窗插件：wcPop 打包工具：webpack 2.0 环境配置：node.js cnpm 图片预览：react-photoswipe 轮播滑动：swiper
