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

## Installation

```
npm install react-infinite-scroller --save
```
```
yarn add react-infinite-scroller
```

## How to use

```js
import InfiniteScroll from 'react-infinite-scroller';
```

### Window scroll events

```js
<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

```js
<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.

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