Since V2 classes often don't get added on scroll

[andre-lergier]

Since Version 2 unfortunately the plugin doesn't work very reliable anymore.

With the following code the plugin adds the class to the elements which are already in the viewport on page load.
While scrolling, the defined class gets added only very rarely to appearing elements - most of the time never. In my case this means, that the elements just never show up, what's a huge problem.

import ViewportChecker from 'viewport-checker';

document.addEventListener('DOMContentLoaded', () => {
  const vpc = new ViewportChecker('[data-in-vp-animation]', {
    classToAdd: 'in-vp',
    removeClassAfterAnimation: false,
    offset: `${10}%`,
  });

  vpc.attach();
});

If I change back to Version 1 using jQuery, everything works as expected:

import $ from 'jquery';
import 'jquery-viewport-checker';

document.addEventListener('DOMContentLoaded', () => {
  $('[data-in-vp-animation]').viewportChecker({
    classToAdd: 'in-vp',
    removeClassAfterAnimation: false,
    offset: `${10}%`,
  });
});
