一、專案介紹
前幾天有開發過一個react版仿微信手機端聊天室
這次使用react+react-dom+react-router-dom+redux+react-redux+webpack2.0+nodejs等技術開發的仿微信web端聊天,實現了聊天記錄右鍵選單、傳送訊息、表情(動圖),圖片、視訊預覽,瀏覽器截圖貼上傳送等功能。
二、技術選型
- MVVM框架:react / react-dom
- 狀態管理:redux / react-redux
- 頁面路由:react-router-dom
- 彈窗外掛: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
