eslint-plugin-jsx-a11y is an ESLint plugin that statically analyzes JSX code to detect accessibility violations in React applications.
The plugin addresses the problem of catching accessibility issues early in development by performing static analysis of JSX elements without requiring runtime execution. It examines the abstract syntax tree to identify common accessibility mistakes such as missing alt text, improper ARIA attributes, and semantic HTML violations. The tool is designed to work alongside runtime testing tools like axe-core, catching issues that static analysis can detect while acknowledging that comprehensive accessibility testing requires both static checks and testing with assistive technology.
Teams building React applications should adopt this plugin if accessibility compliance is a priority and they want automated detection of common accessibility patterns in their codebase. It suits projects already using ESLint and integrates into both legacy and flat ESLint configuration formats. The plugin provides two shareable configurations—recommended and strict—allowing teams to choose their enforcement level. It works well as part of a broader accessibility testing strategy rather than as a standalone solution.
The project maintains active continuous integration with passing checks on the main branch. The codebase has established test coverage tracking. The plugin provides both legacy and modern ESLint configuration support, indicating ongoing maintenance to align with ESLint's evolving standards. Documentation is available in multiple languages, reflecting effort to serve a diverse user base.
