eslint-plugin-jsx-a11y is a free ESLint plugin that checks JSX in React applications for accessibility issues in static code.
What eslint-plugin-jsx-a11y is
eslint-plugin-jsx-a11y is a free ESLint plugin that checks JSX in React applications for accessibility issues in static code. It offers recommended and strict rule configurations, including options for legacy .eslintrc and flat eslint.config.js setups. Its rules cover ARIA properties, values and roles, alternative text, labels, keyboard access, and captions for audio and video. For example, checks can flag clickable elements that are not interactive but lack keyboard listeners, or interactive handlers on elements that cannot receive focus. Teams can configure mappings between custom components and DOM element types, as well as between DOM attributes and JSX properties. An optional polymorphicPropName setting is available, though the project warns that polymorphic components can make code harder to maintain. Installation instructions cover npm and Yarn, and ESLint must be installed separately. Static checks do not evaluate the rendered DOM; the maintainers recommend adding @axe-core/react and assistive technology testing. The repository links to Tidelift for professional support. The package is MIT-licensed and listed as free.
Good
- Recommended and strict rule configurations are available.
- Checks ARIA, labels, keyboard access, and captions.
- Custom components and JSX properties can be mapped.
- MIT-licensed, with a free plan.
Watch out
- Checks static code, not the rendered DOM.
- Requires ESLint to be installed separately.
- No manual review tools, mobile testing, or browser extension.
Who it suits
It suits React developers who want accessibility checks within an ESLint workflow. Teams needing checks of rendered pages should supplement its static analysis with DOM and assistive technology testing.
Verdict
eslint-plugin-jsx-a11y adds focused accessibility rules to JSX linting, with configurable checks for custom components. Treat it as one part of accessibility review, not a substitute for rendered-DOM and assistive technology testing.
