🎯 Quick Start

import { CeriousScroll } from '@ceriousdevtech/cerious-scroll';

const data = Array.from({ length: 10000 }, (_, i) => ({
  id: i,
  content: `Item ${i}`
}));

const container = document.getElementById('scroll-container');

const scroller = new CeriousScroll(
  container,
  data.length,
  40
);

container.addEventListener('cerious-viewport-change', () => {
  scroller.renderViewport(
    container.clientHeight,
    container,
    (index, element) => {
      element.innerHTML = `<div class="item">${data[index].content}</div>`;
      return element.offsetHeight;
    }
  );
});

container.dispatchEvent(new CustomEvent('cerious-viewport-change'));
