React Shortcuts

Manage keyboard shortcuts from one place.

Build Status


Managing keyboard shortcuts can sometimes get messy. Or always, if not implemented the right way.

Real problems:

  • You can't easily tell which shortcut is bound to which component
  • You have to write a lot of boilerplate code (addEventListeners, removeEventListeners, ...)
  • Memory leaks are a real problem if components don’t remove their listeners properly
  • Platform specific shortcuts is another headache
  • It's more difficult to implement feature like user-defined shortcuts
  • You can't easily get allthe application shortcuts and display it (e.g. in settings)

React shortcuts to the rescue!

With react-shortcuts you can declaratively manage shortcuts for each one of your React components.

Important parts of React Shortcuts:

  • Your keymap definition
  • ShortcutManager which handles keymap
  • <Shortcut> component for handling shortcuts

Quick tour

1. npm install react-shortcuts

2. Define application shortcuts

Create a new JS, Coffee, JSON or CSON file wherever you want (which probably is your project root). And define the shortcuts for your React component.

Keymap definition

 "Namespace": {
   "Action": "Shortcut",
   "Action_2": ["Shortcut", "Shortcut"],
   "Action_3": {
     "osx": "Shortcut",
     "windows": ["Shortcut", "Shortcut"],
     "linux": "Shortcut",
     "other": "Shortcut"
  • Namespace should ideally be the component’s displayName.
  • Action describes what will be happening. For example MODAL_CLOSE.
  • Keyboard shortcut can be a string, array of strings or an object which specifies platform differences (Windows, OSX, Linux, other). The shortcut may be composed of single keys (a, 6,…), combinations (command+shift+k) or sequences (up up down down left right left right B A).

Combokeys is used under the hood for handling the shortcuts. Read more about how you can specify keys.

Example keymap definition:
export default {
    MOVE_LEFT: 'left',
    MOVE_RIGHT: 'right',
    MOVE_UP: ['up', 'w'],
    DELETE: {
      osx: ['command+backspace', 'k'],
      windows: 'delete',
      linux: 'delete',

Save this file as keymap.[js|coffee|json|cson] and require it into your main file.

import keymap from './keymap'

3. Rise of the ShortcutsManager

Define your keymap in whichever supported format but in the end it must be an object. ShortcutsManager can’t parse JSON and will certainly not be happy about the situation.

import keymap from './keymap'
import { ShortcutManager } from 'react-shortcuts'
const shortcutManager = new ShortcutManager(keymap)
// Or like this
const shortcutManager = new ShortcutManager()

4. Include shortcutManager into getChildContext of some parent component. So that <shortcuts> can receive it.

class App extends React.Component {
  getChildContext() {
    return { shortcuts: shortcutManager }
App.childContextTypes = {
  shortcuts: PropTypes.object.isRequired

5. Require the component

You need to require the component in the file you want to use shortcuts in. For example <TodoItem>.

import { Shortcuts } from `react-shortcuts`
class TodoItem extends React.Component {
  _handleShortcuts = (action, event) => {
    switch (action) {
      case 'MOVE_LEFT':
        console.log('moving left')
      case 'MOVE_RIGHT':
        console.log('moving right')
      case 'MOVE_UP':
        console.log('moving up')
      case 'COPY':
        console.log('copying stuff')
  render() {
    return (
        <div>Make something amazing today</div>

The <Shortcuts> component creates a <shortcuts> element in HTML, binds listeners and adds tabIndex to the element so that it’s focusable. _handleShortcuts is invoked when some of the defined shortcuts fire.

Custom props for <Shortcuts> component

  • handler: func
    • callback function that will fire when a shortcut occurs
  • name: string
    • The name of the namespace specified in keymap file
  • tabIndex: number
    • Default is -1
  • className: string
  • eventType: string
    • Just for gourmets (keyup, keydown, keypress)
  • stopPropagation: bool
  • preventDefault: bool
  • targetNodeSelector: DOM Node Selector like body or .my-class
    • Use this one with caution. It binds listeners to the provided string instead of the component.
  • global: bool
    • Use this when you have some global app wide shortcuts like CMD+Q.
  • isolate: bool
    • Use this when a child component has React's key handler (onKeyUp, onKeyPress, onKeyDown). Otherwise, React Shortcuts stops propagation of that event due to nature of event delegation that React uses internally.
  • alwaysFireHandler: bool
    • Use this when you want events keep firing on the focused input elements.
