EAA compliance for React: WCAG 2.1 AA checklist & fixes

What the EAA actually requires from a React site

The European Accessibility Act (Directive 2019/882) applies to consumer-facing online services from 28 June 2025. For a React site selling to EU consumers, that means the storefront, checkout, account area, and any embedded payment flow have to meet WCAG 2.1 Level AA via the harmonised standard EN 301 549. Microenterprises with under 10 employees and below €2 million in turnover are exempt for services, but not for products.

Fines vary by member state. Germany caps individual penalties at €100,000; France can fine up to 4% of group turnover; Spain reaches €600,000 for serious or repeated breaches. None of those numbers are theoretical — market surveillance authorities have already started auditing storefronts in Germany and France in the run-up to enforcement.

In practice, the work breaks down into three buckets: theme-level fixes (focus styles, contrast, semantics), interaction-level fixes (carousels, modals, drawers, gallery widgets), and content-level fixes (alt text, headings, descriptive link text). The list below covers the React-specific failure points we see most often during scans.

Top WCAG failures we see on React sites

Across hundreds of React scans, the same handful of issues show up over and over. None of them require ripping the theme apart — most are fixable in a few hours by someone comfortable in the platform's editor or template files.

• Custom modals without focus trap or restore

  Hand-rolled <div> modals usually skip Tab cycling and never restore focus to the trigger. Use a vetted library (Radix, React Aria, Headless UI).

  2.4.3, 2.1.2 — Level A

• Click-only ARIA roles

  role="button" on a <div> needs onKeyDown for Enter and Space. Most teams forget the keyboard half.

  2.1.1, 4.1.2 — Level A

• SPA route changes are silent

  react-router and react-navigation do not notify assistive tech when the URL changes.

  4.1.3 — Level AA

Concrete code fixes for React

Below are copy-paste fixes for the most common React issues. They assume you have access to your theme code or the platform's custom-code injection panel. If you cannot edit code directly, share these snippets with whoever maintains the site — every one of them is a ten-minute change.

import * as Dialog from '@radix-ui/react-dialog';

export function MyModal() {
  return (
    <Dialog.Root>
      <Dialog.Trigger>Open</Dialog.Trigger>
      <Dialog.Portal>
        <Dialog.Overlay />
        <Dialog.Content>
          <Dialog.Title>Title</Dialog.Title>
          <Dialog.Close>Close</Dialog.Close>
        </Dialog.Content>
      </Dialog.Portal>
    </Dialog.Root>
  );
}

Tools and plugins worth installing first

• eslint-plugin-jsx-a11y

• @axe-core/react in development

• Storybook a11y addon for per-component checks

How to scan a React site without missing anything

Automated scanners catch about 30–40% of WCAG issues; the rest need manual review. The good news is that the 30–40% includes the most expensive issues to remediate after the fact, so an automated scan is the cheapest way to get unstuck. Run one before you change a line of theme code.

• Run scans against the production bundle, not development. Hot reload can mask issues.
