For example you can use Refs to Components approach like so:

/* Child.js */
import React from 'react'
import withStyles from 'isomorphic-style-loader/lib/withStyles'
import s from './Child.css'

class Child extends React.Component {
  componentDidMount() {
    this.props.onRef(this)

 * @param {Number} [fontscale = 1] - 有的业务希望能放大一定比例的字体;
 */
const win = window;
export default win.flex = (baseFontSize, fontscale) => {
  const _baseFontSize = baseFontSize || 100;
  const _fontscale = fontscale || 1;
