react-infinite-scroll-component npm npm

A component to make all your infinite scrolling woes go away with just 4.15 kB! Pull Down to Refresh feature added. An infinite-scroll that actually works and super-simple to integrate!

install

  npm install --save react-infinite-scroll-component

  // in code ES6
  import InfiniteScroll from 'react-infinite-scroll-component';
  // or commonjs
  var InfiniteScroll = require('react-infinite-scroll-component');

using

<InfiniteScroll
  dataLength={items.length} //This is important field to render the next data
  next={fetchData}
  hasMore={true}
  loader={<h4>Loading...</h4>}
  endMessage={
    <p style={{textAlign: 'center'}}>
      <b>Yay! You have seen it all</b>
    </p>
  }
  // below props only if you need pull down functionality
  refreshFunction={this.refresh}
  pullDownToRefresh
  pullDownToRefreshContent={
    <h3 style={{textAlign: 'center'}}>&#8595; Pull down to refresh</h3>
  }
  releaseToRefreshContent={
    <h3 style={{textAlign: 'center'}}>&#8593; Release to refresh</h3>
  }>
  {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.
dataLength number set the length of the data.This will unlock the subsequent calls to next.
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 | string A threshold value defining when InfiniteScroll will call next. Default value is 0.8. It means the next will be called when user comes below 80% of the total height. If you pass threshold in pixels (scrollThreshold="200px"), next will be called once you scroll at least (100% - scrollThreshold) pixels down.
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
className string add any custom class you want
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 or string optional, reference to a (parent) DOM element that is already providing overflow scrollbars to the InfiniteScroll component. You should provide the id of the DOM node preferably.
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.
key string the key for the current data set being shown, used when the same component can show different data sets at different times, default=undefined
You can’t perform that action at this time.
