  • Virtual Scroll for Angular

    Angular Virtual Scroll that displays a small subset of records, just enough to fill the viewport, and uses the same DOM elements as the user scrolls.

    This method is effective because the number of DOM elements is always constant and tiny irrespective of the size of the list. Thus, the virtual scroll can display endlessly, efficiently growing a list of items.

    This open source project is an Angular-compatible module that has an easy-to-use API and supports multi-columns. We achieved 82,000 downloads.
