Readme
This library is used in ember-in-viewport. This library is particularly important for re-using the IntersectionObserver API. IntersectionObserver.observer can observer multiple elements. So this library will resuse the IntersectionObserver instance for another element on the page with the same set of observer options and root element. This can dramatically improve performance for pages with lots of elements and observers.
npm install intersection-observer-admin --save
import IntersectionObserverAdmin from 'intersection-observer-admin';
const intersectionObserverAdmin = new IntersectionObserver();
// add an element to static administrator
intersectionObserverAdmin.add(element, enterCallback, exitCallback, { root, rootMargin: '0px 0px 100px 0px', threshold: 0 });
// remove an element from the static administrator
intersectionObserverAdmin.add(element, enterCallback, exitCallback, { root, rootMargin: '0px 0px 100px 0px', threshold: 0 }, '.my-list');
// Use in cleanup lifecycle hooks (if applicable) from the element being observed
intersectionObserverAdmin.unobserve(element, observerOptions, scrollableArea);
// Use in cleanup lifecycle hooks of your application as a whole
// This will remove the in memory data store holding onto all of the observers
intersectionObserverAdmin.destroy();
