A simple infinite loading list in React

A simple infinite loading list in React

react-simple-infinite-loading

Someone pointed out the React implementation of the list was a bit complex. I figure out it was possible to write an abstraction for this particular case. Here it is!

This component aims to stay easy to use. If your use case needs more options I recommend using directly awesome libraries from Brian Vaughn listed in dependencies section.

react-simple-infinite-loading

Install

npm install --save react-simple-infinite-loading

Usage

import React from 'react'

import InfiniteLoadingList from 'react-simple-infinite-loading'

function Example({ items, fetchMore, hasMore }) {
  return (
    <div style={{ width: 300, height: 300 }}>
      <InfiniteLoading
        items={items}
        itemHeight={40}
        hasMoreItems={hasMore}
        loadMoreItems={fetchMore}
      >
        {({ item }) => <div>{item}</div>}
      </InfiniteLoading>
    </div>
  )
}

Dependencies

react-simple-infinite-loading has only three dependencies:

  • react-window is made to display efficiently large lists. It only creates components for the visible elements and reuse nodes.
  • react-window-infinite-loader is a HOC that loads elements just-in-time as user scrolls down the list
  • react-virtualized-auto-sizer helps you displaying your list so it fits the space available in its parent container.
