Swipe Event Listener

swipe-event-listener is a very minimal library that allows listening for swipe gesture, including the ones from the mouse from any DOM element. Once invoked with a DOM element, simply listen for swipe events.

Installation

Browser

<script src="https://unpkg.com/swipe-event-listener@1.2.1/dist/swipe-event-listener.js"></script>

Then anywhere in your JavaScript code.

const { SwipeEventListener } = window.SwipeEventListener;

OR

const SwipeEventListener = window.SwipeEventListener.SwipeEventListener;

Via NPM

npm i swipe-event-listener

Then anywhere in your code.

import { SwipeEventListener } from 'swipe-event-listener';

OR

const SwipeListener = require('swipe-listener');

How to use it

const { swipeArea, updateOptions } = SwipeEventListener({
  swipeArea: document.querySelector('body'),
});

swipeArea.addEventListener('swipeDown', () => {
  console.log('swipe down');
});
swipeArea.addEventListener('swipeUp', () => {
  console.log('swipe up');
});

swipeArea.addEventListener('swipeLeft', () => {
  console.log('swipe left');
});

swipeArea.addEventListener('swipeRight', () => {
  console.log('swipe right');
});

const SwipeEventListener: (
  customOptions: Options,
) => {
  swipeArea: HTMLElement;
  updateOptions: (newOptions: Options) => void;
};
