eslint-plugin-jsx-a11y review

Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026

eslint-plugin-jsx-a11y is an open-source ESLint plugin for React and other JSX-based applications. It analyzes JSX source code for accessibility issues such as missing alternative text, invalid ARIA properties, inaccessible labels, keyboard interaction problems, and unsuitable element roles. It is aimed at development teams that want accessibility rules applied within their existing ESLint workflow, especially teams enforcing JSX standards across React components.

The project is free and open source, with no paid tier described. Its published feature set includes recommended and strict shareable configurations, plus ESLint flat configuration support. Teams can customize component-to-DOM element mappings and JSX attribute mappings, while polymorphic component analysis helps account for components that can render different element types. Because ESLint is the listed integration, the product fits teams already organizing code quality checks around that ecosystem rather than teams seeking a separate accessibility platform.

Its strongest focus is static coverage across common JSX accessibility concerns. Rules address ARIA, labels, alternative text, keyboard access, roles, focus, and media captions, giving developers a broad set of source-level checks. That focus also defines its boundaries: it does not test rendered DOM behavior, provide manual review tools, support mobile testing, or replace assistive-technology testing. Teams choosing eslint-plugin-jsx-a11y should want an accessible JSX coding layer and be prepared to combine it with rendered-DOM and assistive-technology testing. Teams seeking mobile coverage, browser-based checks, or remediation workflows should choose a broader accessibility testing product instead.
