react+redux仿微信聊天界面

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

◆ 入口页面index.js配置

/*
 * @desc 入口页面index.js
 */
import react from 'react';
import reactdom from 'react-dom';
// import {hashrouter as router, route} from 'react-router-dom'
import app from './app';
// 引入状态管理
import {provider} from 'react-redux'
import {store} from './store'
// 导入公共样式
import './assets/fonts/iconfont.css'
import './assets/css/reset.css'
import './assets/css/layout.css'
// 引入wcpop弹窗样式
import './assets/js/wcpop/skin/wcpop.css'
// 引入js
import './assets/js/fontsize'
reactdom.render(
 <provider store={store}>
  <app />
 </provider>,
 document.getelementbyid('app')
);

◆ 页面app.js主模板

import react, { component } from 'react';
import {hashrouter as router, route, switch, redirect} from 'react-router-dom'
import {connect} from 'react-redux'
import $ from 'jquery'
// 引入wcpop弹窗插件
import { wcpop } from './assets/js/wcpop/wcpop'
// 引入地址路由
import routers from './router'
// 导入顶部、底部tabbar
import headerbar from './components/header'
import tabbar from './components/tabbar'
class app extends component {
 constructor(props){
  super(props)
  console.log('app主页面参数：\n' + json.stringify(props, null, 2))
 }
 render() {
  let token = this.props.token
  return (
   <router>
    <div classname="wechatim__panel clearfix">
     <div classname="we__chatim-wrapper flexbox flex__direction-column">
      {/* 顶部 */}
      <switch>
       <headerbar />
      </switch>
      {/* 主页面 */}
      <div classname="wcim__container flex1">
       {/* 路由容器 */}
       <switch>

            token ? <item.component {...props} /> : <redirect to={{pathname: '/login', state: {from: props.location}}} />
           )
          )} />
         })
        }
        {/* 初始化页面跳转 */}
        <redirect push to="/index" />
       </switch>
      </div>
      {/* 底部tabbar */}
      <switch>
       <tabbar />

    </div>
   </router>
  );
 }
}
const mapstatetoprops = (state) =>{
 return {
  ...state.auth
 }
}
export default connect(mapstatetoprops)(app);
