Examples

Many react-virtualized components require explicit dimensions but sometimes you just want a component to just grow to fill all of the available space. The AutoSizer component can be useful in this case.

One word of caution about using AutoSizer with flexbox containers. Flex containers don't prevent their children from growing and AutoSizer greedily grows to fill as much space as possible. Combining the two can cause a loop. The simple way to fix this is to nest AutoSizer inside of a block element (like a <div>) rather than putting it as a direct child of the flex container.

import React from 'react';
import ReactDOM from 'react-dom';
import { AutoSizer, List } from 'react-virtualized';
import 'react-virtualized/styles.css'; // only needs to be imported once

// List data as an array of strings
const list = [
  'Brian Vaughn'
  // And so on...
];

function rowRenderer ({ key, index, style}) {
  return (
    <div
      key={key}
      style={style}
    >
      {list[index]}
    </div>
  )
}

// Render your list
ReactDOM.render(
  <AutoSizer>
    {({ height, width }) => (
      <List
        height={height}
        rowCount={list.length}
        rowHeight={20}
        rowRenderer={rowRenderer}
        width={width}
      />
    )}
  </AutoSizer>,
