KeyMapper Component

Simple utility component useful for handling keyboard shortcuts for triggering UI elements used frequently in development.

Usage

// need to make npm package for this
import KeyMapper, { CTRL, SHIFT } from 'react-keymapper';

export default class App {
  render() {
    return (
      <section>
        <KeyMapper show={[CTRL, SHIFT, 's']} hide={[CTRL, SHIFT, 'h']}>
          {() => <div>Some component to render when triggered</div>}
        </KeyMapper>
      </section>
    );
  }
}

All you have to do is provide a callback function for the KeyMapper component to call whenever your show combination is triggered. When you trigger your hide combination, KeyMapper will just render null.

Support

Currently, KeyMapper supports the ALT, CTRL, and SHIFT modifier keys on a keyboard. Please use at least one modifier key along with a letter in your trigger combination.
