react聊天室|react+redux仿微信聊天IM实例|react仿微信界面

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
