Key

Key is a tiny little keycode library for your browser. It makes keybound event assertions super simple.

Example

Here's how key can work together with a DOM query library like jQuery to navigate through a [pseudo] image gallery.

var gallery = new GalleryOfAwesome();

$(window).on('keyup', function(event) {
    if (key.is(key.code.arrow.left, event.which)) {
        gallery.navigateLeft();
    } else if (key.is(key.code.arrow.right, event.which)) {
        gallery.navigateRight();
    } else if (key.is(key.code.special.esc, event.which)) {
        gallery.close();
    }
});

You can even assert against a collection of keys, not just a specific key.

var input = $('input[type="text"]');

input.on('keydown', function (event) {
    if (key.is(key.code.punctuation, event.which)) {
        event.preventDefault();
        window.alert('No punctuation allowed!');
    }
});

Usage

var key = window.key; // In browser
var key = require('key'); // Or package manager

Installation

  • npm install key
