【心有猛虎】react-pxq

标签：返回   icon   copy   ogg   bin   mod   解决   bool   rop   

这是一个比较完整的简单的react移动端项目，说起来页面少，其实，构思若是精巧，也并不容易做
先放源码：https://github.com/bailicangdu/react-pxq



接下来我们简单的看看代码
项目有用到react-redux和axios处理数据

//根index.js引用了一些基本的方法
//定义了渲染组件  <Component />
import React from 'react';
import ReactDOM from 'react-dom';
import Route from './router/';
import FastClick from 'fastclick';
import registerServiceWorker from './registerServiceWorker';
import { AppContainer } from 'react-hot-loader';
import {Provider} from 'react-redux';
import store from '@/store/store';
import './utils/setRem';
import './style/base.css';
//解决tab穿透的问题
FastClick.attach(document.body);

// 监听state变化
// store.subscribe(() => {
//   console.log('store发生了变化');
// });

const render = Component => {
  ReactDOM.render(
    //绑定redux、热加载
    <Provider store={store}>
      <AppContainer>
        <Component />
      </AppContainer>
    </Provider>,
    document.getElementById('root'),
  )
}

render(Route);

// Webpack Hot Module Replacement API
if (module.hot) {
  module.hot.accept('./router/', () => {
    render(Route);
  })
}

registerServiceWorker();

//src/utils/setRem.js
//定义的是单位的转换
(function(psdw){
  var dpr=0 , rem=0 , scale=0;
  var htmlDOM=document.documentElement;
  dpr=window.devicePixelRatio;
  var currentWidth=htmlDOM.clientWidth;
  scale=currentWidth/psdw;
  rem=psdw/10;
  rem=rem*scale;
  htmlDOM.style.fontSize=rem+'px';
  htmlDOM.setAttribute('data-dpr',dpr)
})(750)

//src/store/store.js
//与store相对的就是reducer和action
//这里用到的是react-thunk
