一、项目介绍

基于react+react-dom+react-router-dom+redux+react-redux+webpack2.0+nodejs等技术混合开发的仿微信web端聊天室reactwebchat项目,实现了聊天记录右键菜单、发送消息、表情(动图),图片、视频预览,浏览器截图粘贴发送等功能。

二、技术选型

  • 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

◆ app主页面布局及路由配置:

render() {
    let token = this.props.token
    return (
      <router>
        <div classname="vchat-wrapper flexbox flex-alignc">
          <div classname="vchat-panel" /*style={{ backgroundimage: `url(${require("./assets/img/placeholder/vchat__panel-bg02.jpg")})` }}*/ >
            <div classname="vchat-inner flexbox">
              {/* //顶部(最大、最小、关闭) */}
              <switch>
                <winbar />
              </switch>

              {/* //侧边栏 */}
              <switch>
                <sidebar />
              </switch>

              {/* //主页面 */}
              <div classname="flex1 flexbox">
                {/* 路由容器 */}
                <switch>
                  {
                    routers.map((item, index) => {
                      return <route key={index} path={item.path} exact render={props => (
                        !item.meta || !item.meta.requireauth ? (<item.component {...props} />) : (
                          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>

          </div>
        </div>
      </router>
    );

◆ react+react-redux配合状态管理:

import {combinereducers} from 'redux'
import defaultstate from './state.js'

function auth(state = defaultstate, action) {
    // 不同的action处理不同的逻辑
    switch (action.type) {
        case 'set_token':
            return {
                ...state, token: action.data
            }
        case 'set_user':
            return {
                ...state, user: action.data
            }
        case 'set_logout':
            return {
                user: null, token: null
            }
        default:
            return { ...state }
    }
}

◆ react页面路由配置:
