react开发中如何使用require.ensure加载es6风格的模块

import React, {Component} from ‘react‘;
export default class Container extends Component {
    constructor() {
        super();
        this.state = {
            currentComponent: null
        }
    }

    doSomething = () => {
        require.ensure([‘./app2‘], (require) => {
            const Comp = require(‘./app2‘);
            this.setState({
                currentComponent: <Comp/>
            })
        })
    };

    render() {
        return (
            <div>
                <span onClick={this.doSomething} style={{border: "1px solid #000"}}>点击后，按需加载如下模块</span>
                {this.state.currentComponent}
            </div>
        )
    }
}
 

import React from ‘react‘
export default class Hello extends React.Component {
    render(){
        return (
            <div>Hello</div>
        )
    }
}
//warning:这一句必须加上,因为在require.ensure中使用了require引入模块
module.exports = Hello;
