Description

React puppet lets you update a React Element nested in a render function without re-rendering the owner component.

Why ?

When you have a component with a big render function, it may be bothering that you have to re-render the whole component just to change a prop on an element sitting right in the middle of its render function.

Normally, you shouldn't do that. That's not the React way. Do not use this if you don't understand its purpose !

Usage

import React from 'react';
import puppet from '../src/puppet';
import puppetBadge from './Badge';

const Badge = puppet(puppetBadge);
const Div = puppet('div');

class App extends React.Component {
  handleClick() {
    // Badge will update only its prop test and will be re-rendered.
    this.refs.Badge.setProps({ test: true });
    // div will replace its props with style and will be re-rendered.
    this.refs.div.replaceProps({ style: { color: 'red' } });
  }

  render() {
    return (
      <div>
        <button onClick={ ::this.handleClick }>Click me</button>
        <Badge title='test' ref='Badge'/>
        <Div ref='div' some='prop'>
          Hello
        </Div>
      </div>
    );
  }
}
