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

一、項目概況

基於react+react-dom+react-router-dom+redux+react-redux+webpack2.0+react-photoswipe+swiper等技術混合開發的手機端仿微信界面聊天室——reactChatRoom，實現了聊天記錄下拉刷新、發送消息、表情(動圖)，圖片、視頻預覽，打賞、紅包等功能。

二、技術棧

• MVVM框架：react / react-dom
• 狀態管理：redux / react-redux
• 頁面路由：react-router-dom
• 彈窗插件：wcPop
• 打包工具：webpack 2.0
• 環境配置：node.js + cnpm
• 圖片預覽：react-photoswipe
• 輪播滑動：swiper
