using

<InfiniteScroll
  pullDownToRefresh
  pullDownToRefreshContent={
    <h3 style={{textAlign: 'center'}}>&#8595; Pull down to refresh</h3>
  }
  releaseToRefreshContent={
    <h3 style={{textAlign: 'center'}}>&#8593; Release to refresh</h3>
  }
  refreshFunction={this.refresh}
  next={fetchData}
  hasMore={true}
  loader={<h4>Loading...</h4>}

    <p style={{textAlign: 'center'}}>
      <b>Yay! You have seen it all</b>
    </p>
  }>
  {items}
</InfiniteScroll>

The InfiniteScroll component can be used in three ways.

• Specify a value for the height prop if you want your scrollable content to have a specific height, providing scrollbars for scrolling your content and fetching more data.
• If your scrollable content is being rendered within a parent element that is already providing overflow scrollbars, you can set the scrollableTarget prop to reference the DOM element and use it's scrollbars for fetching more data.
• Without setting either the height or scrollableTarget props, the scroll will happen at document.body like Facebook's timeline scroll.

props

name | type | description -----|------|------------ next | function | a function which must be called after reaching the bottom. It must trigger some sort of action which fetches the next data. The data is passed as children to the InfiniteScroll component and the data should contain previous items too. e.g. Initial data = [1, 2, 3] and then next load of data should be [1, 2, 3, 4, 5, 6]. hasMore | boolean | it tells the InfiniteScroll component on whether to call next function on reaching the bottom and shows an endMessage to the user children | node (list) | the data items which you need to scroll. loader | node | you can send a loader component to show while the component waits for the next load of data. e.g. <h3>Loading...</h3> or any fancy loader element scrollThreshold | number | a threshold value after that the InfiniteScroll will call next. By default it's 0.8. It means the next will be called when the user comes below 80% of the total height. onScroll | function | a function that will listen to the scroll event on the scrolling container. Note that the scroll event is throttled, so you may not receive as many events as you would expect. endMessage | node | this message is shown to the user when he has seen all the records which means he's at the bottom and hasMore is false style | object | any style which you want to override height | number | optional, give only if you want to have a fixed height scrolling content scrollableTarget | node | optional, reference to a (parent) DOM element that is already providing overflow scrollbars to the InfiniteScroll component. hasChildren | bool | children is by default assumed to be of type array and it's length is used to determine if loader needs to be shown or not, if your children is not an array, specify this prop to tell if your items are 0 or more. pullDownToRefresh | bool | to enable Pull Down to Refresh feature pullDownToRefreshContent | node | any JSX that you want to show the user, default={<h3>Pull down to refresh</h3>} releaseToRefreshContent | node | any JSX that you want to show the user, default={<h3>Release to refresh</h3>} pullDownToRefreshThreshold | number | minimum distance the user needs to pull down to trigger the refresh, default=100px refreshFunction | function | this function will be called, it should return the fresh data that you want to show the user initialScrollY | number | set a scroll y position for the component to render with.
