EN 301 549 on Next.js: complete compliance checklist
Implementing EN 301 549 compliance on Next.js means addressing the platform's specific failure modes (spa route changes not announced, modal focus management) while applying EN 301 549 — Accessibility requirements for ICT products and services success criteria across content, code, and editorial workflow.
EN 301 549 in 60 seconds
EN 301 549 is the harmonised European standard for digital accessibility, maintained jointly by ETSI, CEN, and CENELEC, that incorporates WCAG 2.1 AA for web and mobile content and adds requirements for hardware, software, documentation and support — and is the technical reference for both the European Accessibility Act and the Web Accessibility Directive.
Next.js accessibility — what you are starting with
Next.js delivers SSR/RSC HTML that is screen-reader friendly out of the box, but client-side interactions (modals, route changes, dynamic content) require explicit accessibility work.
EN 301 549 setup checklist for Next.js
1. Use semantic HTML in components: Prefer button over div + onClick; use header/main/nav.
2. Announce route changes: Use a live region or react-aria utilities to announce.
3. Test with axe-core and AT: Wire @axe-core/react in dev; manual NVDA/VoiceOver pass per page.
Common EN 301 549 failures on Next.js
• SPA route changes not announced
• Modal focus management
• Dynamic content not announced
• Image component alt prop omission
Putting it together
Combine EN 301 549's Level AA requirements with Next.js's native tooling. Bake accessibility into your component library and editorial workflow; instrument axe-core in CI for regression.
