Install

yarn add @closeio/use-infinite-scroll

Benefits

• Extremely lightweight (less than 1KB minzipped).
• It uses the IntersectionObserver API, so it doesn't need to listen to scroll events – which are known to cause performance issues.
• No other 3rd-party dependencies.

Usage

import React from 'react';
import useInfiniteScroll from '@closeio/use-infinite-scroll';

export default function MyComponent() {
  const [items, setItems] = useState([]);
  const [hasMore, setHasMore] = useState(false);
  const [page, loaderRef, scrollerRef] = useInfiniteScroll({ hasMore });

  useEffect(async () => {
    const data = await myApiCall({ page });
    setHasMore(data.hasMore);
    setItems(prev => [...prev, data.items]);
  }, [page]);

  return (
    <div ref={scrollerRef}>
      {items.map(item => (
        <div key={item.id}>{item.name}</div>
      ))}
      {hasMore && <div ref={loaderRef}>Loading…</div>}
    </div>
  );
}
