Usage

// ...
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
import InfiniteAnyHeight from 'react-infinite-any-height';

class App extends Component {
  constructor() {
    super();

    const list = new Array(10000).fill('').map((x, i) => {
      const height = 100 + Math.round(Math.abs((Math.sin(i) * 250)));
      const style = { height, border: 'solid 1px', backgroundColor: `#${height}` };
      return (
        <div key={i} style={style}>
          Height: { height + 2 }
          <div style={{ textAlign: 'center', color: 'white' }}>
            Item: {i}
          </div>
        </div>
      );
    });

    this.state = { list };
  }

  render() {
    return (
      <InfiniteAnyHeight
        list={this.state.list}
        preloadAdditionalHeight={window.innerHeight*2}
        useWindowAsScrollContainer
      />
    );
  }
}

var elemDiv = document.createElement('div')
document.body.appendChild(elemDiv)
ReactDOM.render(<App/>, elemDiv)

All props are passed to react-infinite as well. When updating list make sure to use .slice(0) to change reference. If useWindowAsScrollContainer is ommited, both containerHeight and scrollContainer (the node that has the active .scrollTop) props are required.
