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';

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>
);
