use-infinite-scrolling v1.0.1
use-infinite-scrolling
A React Hook for infinite scrolling on virtually any vertically scrollable element.
Installation
npm install use-infinite-scrolling
Usage
In your component, initialize the Hook using useInfiniteScrolling
like so:
const MyComponent = () => {
const onBottomHit = () => {
console.log('bottom reached');
};
const elemRef = useRef(null);
useInfiniteScrolling(elemRef, onBottomHit, { gap: 0 });
return <div ref={elemRef} />;
}
You must provide at least ref
(first parameter) and onBottomHit
(second parameter) to useInfiniteScrolling
.
Make sure that the element which is targeted via ref
has the overflow-y
CSS property set to auto
or scroll
to enable infinite scrolling.
As a third parameter you may pass a configuration object which currently has one supported property called gap
. It determines the pixel distance between the bottom of the scroll container and the vertical scroll position at which to call onBottomHit
. By default, gap
is zero, or, in other words, onBottomHit
will only be executed when the bottom of the scroll container has been reached (not before). If gap
is set to 100, onBottomHit
will be called as soon as the scroll position is 100 pixels or less before the bottom of the scroll container. If gap
is set to a negative value, it will be evaluated as zero.
