Get Started
npm install react-virtuoso
import * as React from 'react'
import * as ReactDOM from 'react-dom'
import { Virtuoso } from 'react-virtuoso'
const App = () => {
return <Virtuoso style={{ height: '400px' }} totalCount={200} itemContent={index => <div>Item {index}</div>} />
}
ReactDOM.render(<App />, document.getElementById('root'))
Grouped Mode
The GroupedVirtuoso
component is a variant of the "flat" Virtuoso
, with the following differences:
- Instead of
totalCount
, the component exposesgroupCounts: number[]
property, which specifies the amount of items in each group. For example, passing[20, 30]
will render two groups with 20 and 30 items each; - In addition the
itemContent
property, the component requires an additionalgroupContent
property, which renders the group header. ThegroupContent
callback receives the zero-based group index as a parameter.
Grid
The VirtuosoGrid
component displays same sized items in multiple columns.
The layout and item sizing is controlled through CSS class properties, which allows you to use media queries, min-width, percentage, etc.
Table
The TableVirtuoso
component works just like Virtuoso
, but with HTML tables.
It supports window scrolling, sticky headers, sticky columns, and works with React Table and MUI Table.
Works With Your UI Library of Choice
You can customize the markup up to your requirements - check the Material UI list demo. If you need to support reordering, check the React Sortable HOC example.
Documentation and Demos
For in-depth documentation and live examples of the supported features and live demos, check the documentation website.
Browser support
To support legacy browsers, you might have to load a ResizeObserver Polyfill before using react-virtuoso
:
import ResizeObserver from 'resize-observer-polyfill'
if (!window.ResizeObserver)
window.ResizeObserver = ResizeObserver

Fixes and new Features
To run the tests, use npm run test
.
An end-to-end browser-based test suite is runnable with npm run e2e
, with the pages being e2e/*.tsx
and the tests e2e/*.test.ts
.
A convenient way to debug something is to preview the test cases in the browser.
To do that, run npm run browse-examples
- it will open a crude UI that lets you browse the components in the e2e
folder.
