I have a working markup and script to track horizontal swipes on a container using Hammer.js:
const container = document.getElementsByClassName('swiper')[0];
const manager = new Hammer.Manager(container);
const swipe = new Hammer.Swipe();
manager.add(swipe);
manager.on('swipe', event => {
if (event.offsetDirection === 4) {
container.style.background = 'red';
}
if (event.offsetDirection === 2) {
container.style.background = 'blue';
}
});
.swiper {
height: 100vh;
background: grey;
}
<script src="https://hammerjs.github.io/dist/hammer.min.js"></script>
<h1>Some content</h1>
<div class="swiper"></div>
<h1>More content</h1>
Fiddle

This works fine and I'm already triggering a slider with that.
However, the problem is, that all swipe-events seem to be prevented. The user can't scroll up or down anymore on a mobile device. I've tested this on an iPhone with iOS 11.
Is there a way to tell Hammer.js to propagate these events instead of consuming them?
