react-loadable异步组件

1. 安装react-loadable

yarn add react-loadable

2. 使用react-loadable

import Loadable from 'react-loadable';
import React from 'react'

const LoadableComponent = Loadable({
  loader: () => import('./detail'),
  loading: () => <div>正在加载</div>,
});

export default () => <LoadableComponent/>

注释：/detail对应组件被react-loadable封装之后会异步加载。
