Examples

VirtualScroll Example

Below is a simple VirtualScroll example. Each row in the virtualized list is rendered through the use of a rowRenderer function for performance reasons. This function must return an element with a unique key and must fit within the specified rowHeight.

Note that it is very important that rows do not have vertical overflow. This will make scrolling the list difficult (as individual items will intercept the scroll events). For this reason it is recommended that your rows use a style like overflow-y: hidden.)

import React from 'react';
import ReactDOM from 'react-dom';
import { VirtualScroll } from 'react-virtualized';

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

// Render your list
ReactDOM.render(
  <VirtualScroll
    width={300}
    height={300}
    rowsCount={list.length}
    rowHeight={20}
    rowRenderer={
      index => (
        <div key={index}>
          {list[index]}
        </div>
      )
    }
  />,
  document.getElementById('example')
);

FlexTable Example

Below is a very basic FlexTable example. This table has only 2 columns, each containing a simple string. Both have a fixed width and neither is sortable. See here for a more full-featured example including custom cell renderers, sortable headers, and more.

import React from 'react';
import ReactDOM from 'react-dom';
import { FlexTable, FlexColumn } from 'react-virtualized';

// Table data as a array of objects
const list = [
  { name: 'Brian Vaughn', description: 'Software engineer' }
  // And so on...
];

// Render your table
ReactDOM.render(
  <FlexTable
    width={300}
    height={300}
    headerHeight={20}
    rowHeight={30}
    rowsCount={list.length}
    rowGetter={index => list[index]}
  >
    <FlexColumn
      label='Name'
      dataKey='name'
      width={100}
    />
    <FlexColumn
      width={200}
      label='Description'
      dataKey='description'
    />
  </FlexTable>,
  document.getElementById('example')
);

Similar packages

Other packages similar to react-virtualized

react-window

React-window is a complete rewrite of react-virtualized by the same author. It offers similar functionality but with a smaller and faster core. It's designed to be more approachable and easier to use than react-virtualized.

react-infinite

React-infinite is another package for rendering large lists of elements within a scrolling container. It differs from react-virtualized in its API and the way it handles infinite loading, but it also aims to provide efficient rendering for large lists.

react-virtuoso

React-virtuoso is a virtual list component with a simple API that supports variable-sized items and sticky headers. It provides a different approach to virtualization compared to react-virtualized, focusing on simplicity and automatic handling of item heights.

react-list

React-list is a versatile infinite scroll React component. It offers several modes for rendering lists, including simple, variable, and uniform heights. It's a simpler alternative to react-virtualized with fewer features but can be easier to integrate in some cases.
