About
Spectrum UI components in React
What detecting react-aria tells you about a site
react-aria is Adobe's library of unstyled, accessibility-first behaviour hooks, so its presence is a strong signal that the team treats WCAG compliance, keyboard interaction and screen-reader support as first-class requirements rather than an afterthought. This is common in enterprise software, design-system teams and products with regulatory accessibility obligations. Because it ships behaviour without styling, finding it implies a deliberate, build-your-own-components approach where the team owns the visual layer and leans on Adobe for the hard interaction semantics.
Why the exact react-aria version matters
react-aria sits under the larger React Spectrum project and consolidated many individual @react-aria/* packages into a monopackage over time, so the version indicates which packaging era and which hook surface the build uses. Accessibility libraries also accrue meaningful correctness fixes across releases, so the exact version hints at how current the captured a11y behaviour is.
react-aria in a real-world stack
When you find react-aria in a bundle, it rarely travels alone. react-stately, and frequently the broader React Spectrum or a custom design system.
Quick facts
npm install react-ariaCommon pairings
Packages this one expects to find in the same project. Each is also a Sourcemap Explorer detection target.
What react-aria pulls in
react-aria declares 9 direct dependencies — each one also rides into any bundle that ships react-aria, so they are detection targets too. Reading them is a quick way to understand the package's real footprint .
How Sourcemap Explorer detects react-aria
react-aria ships as v3.51.0, published 2026-07-31 and carries 9 direct dependencies, 2 peer dependencies (react, react-dom), 1,316 versions on the registry. Those exact numbers are the footprint Sourcemap Explorer matches when react-aria rides inside a deployed bundle — here is how the detection works.
We catch react-aria from two complementary signals: bundled source paths and the embedded package.json. Modern bundlers (webpack, Vite, esbuild, Rollup, Turbopack) preserve the original node_modules/react-aria/ paths inside the JavaScript sourcemap's sources[] array — that's the canonical signal. When the matching package.json is also captured in sourcesContent[], we read the exact version field — patch number included. No regex guessing, no version inference.
- 1
Confirm the site exposes sourcemaps
In DevTools Network, check the response headers of any application script for `SourceMap` or `X-SourceMap`. Failing that, fetch the script's last 4 KB and look for a `//# sourceMappingURL=` comment — that map is where the `react-aria` paths live.
- 2
Find the package in the bundle
Open DevTools → Network → reload. Click any application script and look at its sourcemap. Inside, search `sources[]` for entries matching `node_modules/react-aria/` — every match confirms the package is bundled. The matching `sourcesContent[i]` for `node_modules/react-aria/package.json` gives you the exact installed version.
- 3
Read the version directly from package.json
Run `jq -r '. as $m | $m.sources | to_entries[] | select(.value | endswith("node_modules/react-aria/package.json")) | $m.sourcesContent[.key] | fromjson | .version' bundle.js.map`. Sourcemap Explorer automates the same query in the popup.
Major releases of react-aria
When each major version first landed. Major bumps are where breaking changes live, so this timeline is the fastest way to date the react-aria version a site actually ships against the ecosystem.

React Spectrum Libraries
A collection of libraries and tools that help you build adaptive, accessible, and robust user experiences.
React Spectrum
A React implementation of Spectrum, Adobe’s design system. Spectrum provides adaptive, accessible, and cohesive experiences for all Adobe applications.
React Aria
A library of unstyled React components and hooks that helps you build accessible, high quality UI components for your application or design system.
React Stately
A library of React Hooks that provides cross-platform state management for your design system.
More information about React Stately
Internationalized
A collection of framework-agnostic internationalization libraries for the web.
Features
- ♿️ Accessible – Accessibility and behavior is implemented according to WAI-ARIA Authoring Practices, including full screen reader and keyboard navigation support. All components have been tested across a wide variety of screen readers and devices to ensure the best experience possible for all users.
- 📱 Adaptive – All components are designed to work with mouse, touch, and keyboard interactions. They’re built with responsive design principles to deliver a great experience, no matter the device.
- 🌍 International – Support over 30 languages is included out of the box, including support for right-to-left languages, date and number formatting, and more.
- 🎨 Customizable – React Spectrum components support custom themes, and automatically adapt for dark mode. For even more customizability, you can build your own components with your own DOM structure and styling using the React Aria and React Stately hooks to provide behavior, accessibility, and interactions.
Getting started
React Spectrum includes several libraries, which you can choose depending on your usecase.
- React Spectrum is an implementation of Adobe's design system. If you’re integrating with Adobe software or would like a complete component library to use in your project, look no further!
- React Aria is a collection of unstyled React components and hooks that helps you build accessible, high quality UI components for your own application or design system. If you're building a component library for the web from scratch with your own styling, start here.
- React Stately is a library of state management hooks for use in your component library. If you're using React Aria, you'll likely also use React Stately, but it can also be used independently (e.g. on other platforms like React Native).

Contributing
One of the goals of the React Spectrum project is to make building design systems and component libraries as easy as possible, while maintaining high quality interactions and accessibility support. We aim to raise the bar for web applications. The best way to achieve that goal is together. We would love contributions from the community no matter how big or small. 😍

FAQ
What is react-aria used for?
Spectrum UI components in React
How can I tell if a website is using react-aria?
Open the page in Chrome with the Sourcemap Explorer extension installed and read the Stack tab. We catch `react-aria` from two complementary signals: `node_modules/react-aria/` paths inside the JavaScript sourcemap, and the embedded `package.json` we read for exact-version detection. Without the extension you can do the same lookup manually in DevTools — the steps are listed in the "How Sourcemap Explorer detects" section above.
How do I find out which version of react-aria a website is running?
Read it straight from the site's JavaScript sourcemap. When a build ships source maps, the bundled `react-aria/package.json` carries the exact `version` string — Sourcemap Explorer extracts it in one click on the Stack tab, and you can do it by hand in DevTools by opening the `.map` file and searching for `node_modules/react-aria/package.json`. That is far more reliable than inferring the version from an asset-hash or a `?ver=` query string, which is all surface-level detectors have to go on. The current npm release is 3.51.0, but real deployments frequently run an older pinned version — which is exactly why reading the bundled number matters.
What is the latest version of react-aria?
3.51.0, as published on the npm registry. The "Recent versions" table on this page lists the most recent 8 releases with their release dates. Sourcemap Explorer reports the version actually bundled into a site, which can lag the latest release by months on real-world deployments.
Is react-aria actively maintained?
Very actively maintained — the last release shipped within the past three months. The last published release was 2026-07-31. Source code: https://github.com/adobe/react-spectrum.
Where can I read more?
Project homepage: https://github.com/adobe/react-spectrum#readme. Source code: https://github.com/adobe/react-spectrum. Published on npm: https://www.npmjs.com/package/react-aria. Licensed as Apache-2.0.
Detected by Sourcemap Explorer
When a bundle ships sourcemaps, we read the embedded package.json for react-aria and report the precise version (the registry's latest is v3.51.0, published 2026-07-31; the bundled copy is often older). Without sourcemaps, an import / require in the page's scripts is enough to flag it.
