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} />
