I need to implement virtual list in vanilla js.
I used this approach:
<script type="module" defer>
import { Virtualizer } from 'https://cdn.jsdelivr.net/npm/@tanstack/virtual-core@3.2.0/+esm';
// other code...
// Initialize the virtualizer
const virtualizer = new Virtualizer({
debug: true,
count: 10000, // The number of items in the list
getScrollElement: () => container,
estimateSize: () => 50, // The estimated size of each item
overscan: 5, // How many items to render outside of the viewport
});
// other code...
const items = virtualizer.getVirtualItems();
// items.length always === 0
</script>
No matter what I do, the array of items is always empty. But virtualizer.measurementsCache.length === 10000.

});
const items = virtualizer.getVirtualItems() should return array with more than zero items
