Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

A word about react-window

If you're considering adding react-virtualized to a project, take a look at react-window as a possible lighter-weight alternative. Learn more about how the two libraries compare here.

Getting started

Install react-virtualized using npm.

npm install react-virtualized --save

ES6, CommonJS, and UMD builds are available with each distribution. 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';

// But if you only use a few react-virtualized components,
// And you're concerned about increasing your application's bundle size,
// You can directly import only the components you need, like so:
import AutoSizer from 'react-virtualized/dist/commonjs/AutoSizer';
import List from 'react-virtualized/dist/commonjs/List';

Note webpack 4 makes this optimization itself, see the documentation.

If the above syntax looks too cumbersome, or you import react-virtualized components from a lot of places, you can also configure a Webpack alias. For example:

// Partial webpack.config.js
{
  alias: {
    'react-virtualized/List': 'react-virtualized/dist/es/List',
  },
  ...rest
}

Then you can just import like so:

import List from 'react-virtualized/List';

// Now you can use <List {...props} />

You can also use 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>

Now you're ready to start using the components. You can learn more about which components react-virtualized has to offer below.

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-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 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.

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 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} />
Public methods

Grid and Collection components can be forcefully re-rendered using forceUpdate. 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

API documentation available here.

There are also a couple of how-to guides:

Examples

Examples for each component can be seen in the documentation.

Here are some online demos of each component:

And here are some "recipe" type demos:

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.

Friends

Here are some great components built on top of react-virtualized:

  • react-infinite-calendar: Infinite scrolling date-picker with localization, themes, keyboard support, and more
  • react-sortable-hoc: Higher-order components to turn any list into an animated, touch-friendly, sortable list
  • react-sortable-tree: Drag-and-drop sortable representation of hierarchical data
  • react-virtualized-checkbox: Checkbox group component with virtualization for large number of options
  • react-virtualized-select: Drop-down menu for React with windowing to support large numbers of options.
  • react-virtualized-tree: A reactive tree component that aims to render large sets of tree structured data in an elegant and performant way
  • react-timeline-9000: A calendar timeline component that is capable of displaying and interacting with a large number of items
