### Usage
 - Install
```bash
npm install m2-react
yarn add m2-react
```
### APIs
 - `render` **function** Render the root component(s) with the param *rootApp*.
 ####
 | param | type | description | default | example |
 | ------------ | ------------ | ------------ | ------------ | ------------ |
 | rootApp | object | the root component(s)|  |
 ```js
 import React from 'react'
 import { render } from 'm2-react'
 import Loading from '@/features/common/components/loading'
 // only for react app
 import App from '@/features/app/containers' 
 // only for redux app
 import { Root } from 'm2-redux'
 import AppRouter from '@/features/app/router' 
 import AppStore from '@/features/app/redux/store'
 
 /* 有以下几种使用方式: */
 // 1. 不通过Redux Root组件渲染
 render (
   <App/>
 )
 
 // 2. 不通过Redux Root组件渲染，同时指定根节点(使用component属性)
 render({
   component: <App/>,
   root: 'app' 
 })
 
 // 3. 通过Redux Root组件渲染
 render(
   <Root {...AppStore} {...AppRouter}/>
 )
 
 // 4. 通过Redux Root组件渲染多组件(使用components属性)
 render({
   components: [
     <Loading key="loading"/>,
     <Root {...AppStore} {...AppRouter} key="root"/>
   ],
   root: 'app' // 指定DOM根元素id,默认为'root'
 })
```
 - `getComponentRef` **function** Get the child component instance with the param *refKey* and *parent*.

```js
import React from 'react'
import { getComponentRef } from 'm2-react'

export default class MyComponent extends React.Component {
  componentDidMount() {
    this.child = getComponentRef('child', this)
  }

  render() {
    return (
      <>
        <child-component ref="child"/>
        <child-component ref={el=>this.child=el}/> { /* Recommend */ }
        <child-component wrappedComponentRef={form=>this.child=form}/>
      </>
    )
  }
}
```
 - `initialFormComponent` **function** Initial the form component for extended on rc-form with the param *component*.

 import { Button } from 'antd-mobile'
 import { PickerItem } from 'm2-antd/mobile' /* 待发布(可用其他组件代替) */
 import { initialFormComponent } from 'm2-react'
 import { district } from 'antd-mobile-demo-data'

 class AppForm extends React.Component {
  componentWillMount() {
    initialFormComponent(this)
  }
  
  submit() {
    console.log(this.form.values)  
  }
  
  render() {
   return (
     <div className="App">
      <PickerItem label="Select District" data={district} field="district" {...this.form}/>
      <Button onClick={()=>this.submit()}>Submit</Button>
     </div>
    ) 
  }
 }
 
 export default createForm()(AppForm)
 
```
 - `loadRoutesConfig` **function** Load the application router configuration with the param *rootApp*,*childRoutes* and *context*.

import commonRouter from '@/features/common/router'
import homeRouter from '@/features/home/router'
// 如增加新的业务模块，需在此注册
// import authRouter from '@/features/auth/router'
