React Component State

Updates the state locally when that same value changes in another component. Simply need to use the following instead of the default react component and use updateState instead of setState :

import Component from 'react-component-state';

export default class Thing1 extends Component {
  render() {
    return (
      <div>{this.state.counter}</div>
    )
  }
}

...

import Component from 'react-component-state';

export default class Thing2 extends Component {
  state = {
    counter: 0
  };
  constructor(props) {
    super(props);
    this.updateCounter = this.updateCounter.bind(this);
  }
  updateCounter() {
    this.updateState({ counter : this.state.counter + 1 })
  }
  render() {
    <button onClick={this.updateCounter}>Click me!</button>
  }
}

...

import { Component } from 'react';
import Thing1 from './thing1';
import Thing2 from './thing2';

export default class App extends Component {
  render() {
    <Thing1 />
    <Thing2 />
  }
}
