## Summary

Single-page applications (SPAs) built with React often carry an industry stigma of being inherently inaccessible. Because SPAs typically render as complex component trees without triggering full page reloads, screen readers and keyboard users frequently lose context, facing disjointed DOM structures, unannounced dynamic changes, and broken focus patterns. Overcoming this stigma requires intentionally adapting traditional web accessibility principles into the React component lifecycle to ensure inclusive user experiences.

The cornerstone of React accessibility is prioritizing semantic HTML over generic `<div>` containers. Using native elements like `<nav>`, `<main>`, and `<button>` directly maps interactive intents to the browser's accessibility tree, granting screen readers built-in keyboard navigation and event handling behaviors. When breaking interfaces into smaller components, React Fragments (`<>...</>`) play a crucial vital role in preventing wrapper elements from breaking valid parent-child HTML structures (like unordered lists). For interactive states, developers must orchestrate keyboard focus management manually using the `useRef` hook. Directing focus when elements are added, edited, or deleted prevents users from becoming stranded or losing their place within complex CRUD operations.

To bridge the gap left by the lack of page refreshes, teams must implement programmatic context updates. Updating the document title dynamically and utilizing ARIA live regions (`aria-live`, `role="status"`) ensures that off-screen changes and notifications are reliably announced to assistive technologies. Finally, maintaining accessible React architectures requires a multi-layered testing strategy. While automated linters like `eslint-plugin-jsx-a11y` and browser extensions like axe DevTools provide an excellent foundational baseline, they only catch programmatic failures. Thorough manual keyboard testing—checking for logical tab orders, robust focus visibility, and the absence of keyboard traps—remains irreplaceable for building a truly accessible, production-ready application.
