Getting started

Install react-virtualized using npm.

npm install react-virtualized --save

ES6, CommonJS, and UMD builds are available with each distribution. For example:

// Make sure to import default styles.
// This only needs to be done once; probably during your application's bootstrapping process.
import 'react-virtualized/styles.css';

// Then you can import any react-virtualized components you need.
// Tree-shaking is supported with ES6 or CommonJS usage.
import { Grid } from 'react-virtualized'

Alternately you can load a global-friendly UMD build:

<link rel="stylesheet" href="path-to-react-virtualized/styles.css">
<script src="path-to-react-virtualized/dist/umd/react-virtualized.js"></script>

Dependencies

React Virtualized has very few dependencies and most are managed by NPM automatically. However the following peer dependencies must be specified by your project in order to avoid version conflicts: react, react-addons-shallow-compare, and react-dom. NPM will not automatically install these for you but it will show you a warning message with instructions on how to install them.

Pure Components

By default all react-virtualized components use shallowCompare to avoid re-rendering unless props or state has changed. This ocassionally confuses users when a collection's data changes (eg ['a','b','c'] => ['d','e','f']) but props do not (eg array.length).

The solution to this is to let react-virtualized know that something external has changed. This can be done a couple of different ways.

Pass-thru props

The shallowCompare method will detect changes to any props, even if they aren't declared as propTypes. This means you can also pass through additional properties that affect cell rendering to ensure changes are detected. For example, if you're using VirtualScroll to render a list of items that may be re-sorted after initial render- react-virtualized would not normally detect the sort operation because none of the properties it deals with change. However you can pass through the additional sort property to trigger a re-render. For example:

<VirtualScroll
  {...virtualScrollProps}
  sortBy={sortBy}
/>

Public methods

Grid and Collection components can be forcefully re-rendered using forceUpdate. For FlexTable and VirtualScroll, you'll need to call forceUpdateGrid) to ensure that the inner Grid is also updated.

Documentation

API documentation available here.

There are also a couple of how-to guides:

• Customizing classes and styles
• Displaying items in reverse order
• Using AutoSizer
• Creating an infinite-loading list
• Displaying a reverse list

Examples

Examples for each component can be seen in the documentation.

Here are some online demos of each component:

• ArrowKeyStepper
• AutoSizer
• CellMeasurer
• Collection
• ColumnSizer
• FlexTable
• Grid
• InfiniteLoader
• ScrollSync
• VirtualScroll
• WindowScroller

And here are some "recipe" type demos:

• Collapsable tree view
• Full-page grid (spreadsheet)
• Dynamic cell measuring
• Cell hover effects

Supported Browsers

react-virtualized aims to support all evergreen browsers and recent mobile browsers for iOS and Android. IE 9+ is also supported (although IE 9 will require some user-defined, custom CSS since flexbox layout is not supported).

If you find a browser-specific problem, please report it along with a repro case. The easiest way to do this is probably by forking this Plunker.
