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
