react-instantiable-stateless

Create stateless React component with instance

Create stateless React component with instance, to use refs, even before React 16.3.

If you are using React 16.3+, you can use React.forwardRef instead.

Example

import React from 'react'
import { findDOMNode } from 'react-dom'
import createInstantiable from 'react-instantiable-stateless'
 
class Wrapper extends React.PureComponent {
  setRef (node) {
    console.log('Just received inner DOM node!', findDOMNode(node))
  }
 
  render () {
    const { children } = this.props
 
    const element = React.Children.only(children)
    const instantiableElement = createInstantiable(element)
    const nextElement = React.cloneElement(
      instantiableElement,
      { ref: node => this.setRef(node) }
    )
 
    return (
      <div className='some-optional-wrapper'>
        {nextElement}
      </div>
    )
  }
}

Requirements

Everything is written in ES5. To make it working in IE8, you need polyfills for ES5, especially:

• Object.assign
• Object.defineProperty
• Object.create
