How to use

import InfiniteScroll from 'react-infinite-scroller';

Window scroll events

<InfiniteScroll
    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
        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.

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