React components for efficiently rendering large lists and tabular data
React components for efficiently rendering large lists and tabular data. Check out the documentation for live examples.

If you're considering adding react-virtualized to a project, take a look at react-window as a possible lighter-weight alternative.
Install react-virtualized using npm.
npm install react-virtualized --save
ES module and CommonJS builds are included, along with TypeScript type definitions. For example:
// Most of react-virtualized's styles are functional (eg position, size). // Functional styles are applied directly to DOM elements. // The Table component ships with a few presentational styles as well. // They are optional, but if you want them you will need to also import the CSS file. // This only needs to be done once; probably during your application's bootstrapping process. import 'react-virtualized/styles.css'; // You can import any component you want as a named export from 'react-virtualized', eg import {Column, Table} from 'react-virtualized';
The package is marked as side-effect free (other than its CSS), so bundlers will tree-shake any components you don't use.
TypeScript types are exported for each component's props (e.g. ListProps, GridProps, TableProps) along with the parameters passed to renderers (e.g. RowRendererParams, CellRendererParams, TableCellProps).
Now you're ready to start using the components. You can learn more about which components react-virtualized has to offer below.
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-dom.
NPM will not automatically install these for you but it will show you a warning message with instructions on how to install them.
By default all react-virtualized components are wrapped in memo to avoid re-rendering unless props or state has changed.
This occasionally 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.
This shallow comparison will detect changes to any props, even ones a component doesn't use.
This means you can also pass through additional properties that affect cell rendering to ensure changes are detected.
For example, if you're using List 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:
<List {...listProps} sortBy={sortBy} />
Grid components can be forcefully re-rendered by calling forceUpdate on their ref.
For Table and List, you'll need to call forceUpdateGrid to ensure that the inner Grid is also updated. For MultiGrid, you'll need to call forceUpdateGrids to ensure that the inner Grids are updated.
Documentation and live examples for every component are available at react-virtualized-docs.vercel.app.
Components:
CellMeasurer measures cells whose sizes aren't known ahead of time.
Grid, List, Masonry and Table can also be scrolled by the window (or another scrollable element) with the scrollElement prop.
Higher-order components:
Note
AutoSizer is no longer part of react-virtualized (as of version 10); it is available as the separate react-virtualized-auto-sizer package.
See sizing components for how to use it with react-virtualized.
There are also a couple of how-to guides:
Here are some "recipe" type demos:
react-virtualized aims to support all evergreen browsers and recent mobile browsers for iOS and Android.
If you find a browser-specific problem, please report it along with a repro case (e.g. a CodeSandbox).
Here are some great components built on top of react-virtualized:
