## What it is
A React library that warns developers about accessibility issues in their React elements at runtime by patching React's rendering functions. It is now deprecated in favor of @axe-core/react.

## Use cases
- find accessibility issues in react components
- warn about missing alt attributes on images
- check aria roles in react app
- audit react app for a11y during development
- catch keyboard accessibility problems in react

## When to choose
- maintaining a legacy codebase that already uses react-a11y
- you need the specific legacy rule set it provides

## When to avoid
- starting a new project - use @axe-core/react instead
- production environments since it patches React rendering and slows it down
- you want actively maintained accessibility tooling

## Facets
- artifact type: library
- maturity: abandoned
- function: accessibility, testing, linter
- domain: accessibility, frontend, web-development
- platform: browser
- tags: react, a11y, deprecated, runtime-auditing, wcag, nodejs, web-server
