use-keyboard-shortcuts

An intuitive React hook to enable keyboard shortcuts.

Quick Example

  useKeyboardShortcuts([
    { keys: ["ctrl", "a"], onEvent: event => alert("ctrl + a was pressed") },
    { keys: ["shift", "b"], onEvent: event => alert("shift + b was pressed") },
    { keys: ["Tab"], handleNext },
    { keys: ["Esc"], handleClose },
    { keys: ["Enter"], handleSubmit, preventDefault: false },
  ])
  useKeyboardShortcuts(
    [{ keys: ["ctrl", "shift"], onEvent: () => alert('ctrl + shift + scroll is active') }],
    true,
    [],
    "mousewheel"
  )
}

Features

Easy to use
Typescript support
Multiple shortcuts registered at the same time
Support for special keys: Shift, Ctrl (command on Mac), Alt (option on Mac).
Support for keydown and mousewheel events
Prevents mature propagation. This means that if you have a shortcut for ctrl + a and ctrl + shift + a in the same hook, then the action
for ctrl + a will not trigger when pressing ctrl + shift + a.

Install

$ npm install --save use-keyboard-shortcuts
$ yarn add use-keyboard-shortcuts

Usage

    { keys: ["Esc"], onEvent: () => setIsOpen(false) },
  ])
  return <div>...</div>
}
