1. written in typescript
2. added a scrollBuffer so that you can start loading the next items before the end is reached

React Progressive List is an alternative to React Virtualized. It wins in two possible scenarios:

1. Your list rows are complex and slow to render. react-virtualized cannot render new rows fast enough to maintain a smooth 60fps scroll.
2. You've tried react-virtualized and found it to be overly complicated for your basic needs.

Example

  renderRow = index => {
    return <Row key={index} avatar={avatars[index]} name={names[index]} />;
  }

  render() {
    return (
      <ReactProgressiveList
        initialAmount={40}
        progressiveAmount={20}
        renderItem={this.renderRow}
        renderLoader={() => <Spinner />}
        rowCount={400}
        scrollBuffer={20}
        useWindowScroll
      />
    );
  }
