$ npm install direction-reveal --save-dev
The script is an ES6(ES2015) module but the compiled version is included in the build as "src/scripts/direction-reveal-umd.js". You can also copy "src/scripts/direction-reveal.js" into your own site if your build process can accommodate ES6 modules.
import DirectionReveal from 'direction-reveal';
// Init with default setup
const directionRevealDemo = DirectionReveal();

itemSelector: '.direction-reveal__card',
animationName: 'swing',
animationPostfixEnter: 'enter',
animationPostfixLeave: 'leave',
enableTouch: true,
touchThreshold: 250

@import "node_modules/direction-reveal/src/styles/direction-reveal.scss";<div class="direction-reveal">
<a href="#" class="direction-reveal__card">
<img src="images/image.jpg" class="direction-reveal__img">
<div class="direction-reveal__overlay direction-reveal__anim--enter">
<h3 class="direction-reveal__title">Title</h3>
<p class="direction-reveal__text">Description text.</p>
</div>
</a>

</div>
The demos use <a> tags for the "direction-reveal__card" but <div> tags can be used as below, specifying the tabindex ensures keyboard navigation works as expected. They can all have a value of 0 and will follow the source order of the divs.
<div class="direction-reveal__card" tabindex="0">
...
</div>
Most of the animations above can be inverted so the overlay is visible by default and animates out on hover. Change the class 'direction-reveal__anim--enter' to 'direction-reveal__anim--leave' for this effect.
You can also add the class 'direction-reveal__anim--enter' or 'direction-reveal__anim--leave' to the image to animate it at the same time as overlay. This effect can be seen in the Slide & Push demo.
A 'directionChange' event is broadcast once a user enters/leaves an item with information about the action(enter,leave) and direction(top, right, bottom, left).
document.querySelector('#test').addEventListener('directionChange', (event) => {
console.log(`Action: ${event.detail.action} Direction: ${event.detail.direction}`);
});
The plugin will detect touch support and reveal the hidden content on first click then follow link on the second click. This can be disabled with the option enableTouch.
Supports all modern browsers(Firefox, Chrome and Edge) released as of January 2018. For older browsers you may need to include polyfills for Nodelist.forEach, Element.classList and Passive Event Listeners.
