Keycodes utilities for WordPress, used to check the key pressed in events like onKeyDown. Contains keycodes constants for keyboard keys like DOWN, UP, ENTER, etc.

Install the module

npm install @wordpress/keycodes --save

This package assumes that your code will run in an ES2015+ environment. If you're using an environment that has limited or no support for ES2015+ such as lower versions of IE then using core-js or @babel/polyfill will add support for these methods. Learn more about it in Babel docs.

Check which key was used in an onKeyDown event:

import { DOWN, ENTER } from '@wordpress/keycodes';

// [...]

onKeyDown( event ) {
	const { keyCode } = event;
	
	if ( keyCode === DOWN ) {
		alert( 'You pressed the down arrow!' );
	} else if ( keyCode === ENTER ) {
		alert( 'You pressed the enter key!' );
	} else {
		alert( 'You pressed another key.' );
	}
}
