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
