bullets-js v1.5.0

BulletsJS

A simple library for common functions.

npm install bullets-js --save-dev

Requirements

You'll need to write some CSS for BulletsJS components to work. You can change the default classes used by passing through the options.

Development

For general developement, use the following command:

npm run serve

NOTE: When testing on older devices (with Browser Stack for example) you might see:

SyntaxError: Unexpected token 'const'

Webpack Dev Server isn't serving babelified code.

It's a pain but I currently do the following (3 separate console tabs):

npm run watch

http-server

(optional) gulp browsersync

public/index.html then pulls in fully babelified code via a script tag.

Using the components

Attach a data-bullets-js attribute to an element to instantiate a class. E.g:

<button data-bullets-js="Modal" >Open Modal</button>

You can then pass through options like so:

<button data-bullets-js="Modal" data-bullets-options="activeClass:open">

Chain options with a comma:

<button data-bullets-js="Modal" data-bullets-options="activeClass:open,targetModal:.js-modal-2">

Modal

The Modal takes two options (default values shown). The class should be instantiated on the button used to trigger the modal.

activeClass: is-open targetModal: .js-modal

The activeClass is applied to the modal, and you should use CSS to then show the modal. For example:

.modal {
	display: none;
}
.modal.is-open {
	display: block;
}

If you want multiple modals on the same page, specify a different targetModal for each modal. You should include an overlay element on your page. A class is added to the body which can be used to make your overlay appear/disappear with the modal. The class added to the body is modal-is-open.

Modal mark-up should be as follows. The modal and modal__inner classes are optional but suggested. You only need one overlay element per page.

The aria-controls attribute should match the id attribute of the modal.

<button class="button" data-bullets-js="Modal" aria-controls="modal">Open Modal</button>

<div class="overlay" tabindex="-1"></div>

<div class="modal js-modal" id="modal" aria-hidden="true" role="dialog" aria-labelledby="dialog-title">		
	<div class="modal__inner" role="document" tabindex="0">

		<button class="js-modal-close button secondary button--hollow">Close</button>
		<h2 id="dialog-title">This is a modal!</h2>

		<!-- your modal content here -->

	</div>
</div>

Menu Toggle

The Menu Toggle takes one option (default values shown). The class should be instantiated on the button used to trigger the menu.

activeClass: menu-is-open

Example CSS might be:

.menu {
	display: none;
}

.menu-is-open .menu {
	display: block;
}

The menu toggle component requires the following mark-up to be accessible.

<button class="menutoggle" data-bullets-js="MenuToggle" id="menu-toggle" aria-label="Menu" aria-expanded="false" aria-controls="menu">

The aria-controls attribute should match the id attribute of the navigation menu. The above button is using menu so the navigation is marked-up as follows.

<nav class="menu" aria-hidden="true" aria-labelledby="menu-toggle" id="menu"></nav>

The behaviour of this component is that it toggles a class on the body element which you can then attach CSS to for making your menu appear and disappear. The component then toggles the necessary aria roles for you to ensure the menu is more accessible.

TESTING

Tested across all devices and browsers finding strong compatibility. ScrollClass may not work on IE11, but it works on Edge 14 up.
