useKey()

npm i @accessible/use-key

A React hook for handling keydown events on specific event.key values. It also normalizes non-standard event.key values from IE to their modern equivalents.

Quick Start

import * as React from 'react'
import useKey from '@accessible/use-key'

const Component = () => {
  const ref = React.useRef(null)

  // Listens to keydown events on the `ref` above
  useKey(ref, {
    // Logs event when the Escape key is pressed
    Escape: console.log,
    // Logs "Key was pressed: Enter" to the console when Enter is pressed
    Enter: (event) => console.log('Key was pressed:', event.key),
  })

  // Listens to keydown events on the window
  useKey(window, {
    // Logs event when the Escape key is pressed
    Escape: console.log,
    // Logs "Key was pressed: Enter" to the console when Enter is pressed
    Enter: (event) => console.log('Key was pressed:', event.key),
  })

  return <div ref={ref} />
}
