Next.js powers high-performance web applications with server-side rendering, static generation, and hybrid rendering modes. While Next.js gives developers full control over the HTML output, its React foundation and client-side routing model create accessibility patterns that differ from traditional websites. Under the EAA, any Next.js application providing services to EU consumers must meet EN 301 549 requirements.
Common Next.js accessibility issues
Client-side route changes don't announce page transitions
Next.js uses client-side routing via next/link and the App Router. When users navigate between pages, the browser doesn't perform a full page load - so screen readers aren't automatically notified that the page has changed. Without explicit focus management and announcements, screen reader users don't know navigation occurred.
Dynamic content loading without live regions
Next.js applications frequently load content dynamically - via API routes, server actions, or client-side data fetching. When content appears or updates without a page reload, screen readers miss the change unless ARIA live regions are implemented.
Image component alt text is optional
Next.js's next/image component requires the alt prop but accepts an empty string. Developers frequently pass empty alt text to suppress linting warnings rather than writing meaningful descriptions, resulting in decorative image treatment for informative images.
Loading and streaming states lack accessibility
Next.js App Router features like loading.tsx, Suspense boundaries, and streaming SSR create intermediate loading states. These loading indicators are often purely visual (spinners, skeleton screens) with no screen reader announcement that content is loading or has loaded.
Head metadata doesn't guarantee accessible document structure
Next.js gives developers full control over document metadata through the Metadata API, but it doesn't enforce accessible document structure. Missing page titles, incorrect language attributes, and absent skip navigation links are common in Next.js applications.
How Lumi works with Next.js
Lumi scans your deployed Next.js application by navigating through client-side routes, waiting for hydration and dynamic content, and testing interactive components in their fully rendered state. Our five engines catch issues in server-rendered HTML, client-hydrated components, and dynamically loaded content. Monitor continuously to catch regressions from deployments.
Next.js-specific WCAG gotchas
Server and client rendering can produce different accessibility
Next.js components can render differently on the server versus the client. A component might have correct ARIA attributes in SSR but lose them after hydration, or vice versa. Only scanning the fully hydrated page catches these mismatches.
Component libraries inherit their own accessibility debt
Next.js projects frequently use third-party component libraries (headless UI, Radix, Material UI). The accessibility quality of these libraries varies, and misconfiguring accessible components is as easy as using them correctly.
Middleware and rewrites can affect accessibility
Next.js middleware that modifies responses (A/B tests, locale redirects, auth gates) can produce different pages for different users. Each variant needs independent accessibility scanning.

Frequently asked questions
Does Next.js handle accessibility automatically?
No. Next.js provides tools (like the Image component and ESLint accessibility rules) but does not enforce accessibility. The framework outputs whatever HTML your components produce - accessible or not.
How do I handle focus management with Next.js routing?
Next.js App Router doesn't manage focus on route changes by default. You need to implement focus management manually - typically by moving focus to the main content area or a heading after navigation, and announcing the new page title to screen readers.
Does the EAA apply to Next.js web applications?
The EAA applies based on what your application does, not what framework it uses. If your Next.js application provides services to EU consumers - e-commerce, banking, content platforms, SaaS tools - it must meet EN 301 549.
Can next/image help with accessibility?
The next/image component requires an alt prop, which is a good forcing function. But it accepts empty strings and doesn't validate alt text quality. Developers still need to write meaningful, descriptive alt text for each image.
