What is @storybook/addon-a11y?
The @storybook/addon-a11y is a Storybook plugin that integrates automated accessibility testing into your component development workflow using the Axe engine. It scans UI components against WCAG standards and identifies accessibility issues related to ARIA, color contrast, keyboard navigation, and other compliance problems. Developers use it to catch accessibility violations early during component development rather than discovering them later in testing or production.
