Infinitely load content using a React Component. This fork maintains a simple, lightweight infinite scroll package that supports both window and scrollable elements.

import InfiniteScroll from 'react-infinite-scroller';

Window scroll events

<InfiniteScroll
    pageStart={0}
    loadMore={loadFunc}
    hasMore={true || false}
    loader={<div className="loader" key={0}>Loading ...</div>}
>
    {items} // <-- This is the content you want to load
</InfiniteScroll>

DOM scroll events

<div style="height:700px;overflow:auto;">
    <InfiniteScroll
        pageStart={0}
        loadMore={loadFunc}
        hasMore={true || false}
        loader={<div className="loader" key={0}>Loading ...</div>}
        useWindow={false}
    >
        {items}
    </InfiniteScroll>
</div>

Custom parent element

You can define a custom parentNode element to base the scroll calulations on.

class InfiniteScrollOverride extends InfiniteScroll {

    /**
     * We are overriding the getParentElement function to use a custom element as the scrollable element
     *
     * @param {any} el the scroller domNode
     * @returns {any} the parentNode to base the scroll calulations on
     *
     * @memberOf InfiniteScrollOverride
     */
    getParentElement(el) {
        if (this.props.scrollParent) {
            return this.props.scrollParent;
        }
        return super.getParentElement(el);
    }

    render() {
        return super.render();
    }
}
