本篇文章介绍react+redux仿微信聊天界面
一、项目概况
基于react+react-dom+react-router-dom+redux+react-redux+webpack2.0+react-photoswipe+swiper等技术混合开发的手机端仿微信界面聊天室——reactChatRoom，实现了聊天记录下拉刷新、发送消息、表情(动图)，图片、视频预览，打赏、红包等功能。
二、技术栈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
