Definition
Reach Router was a routing library for React applications that prioritized keyboard accessibility and screen-reader support as first-class concerns rather than add-ons. It rendered nested routes based on the current URL and managed focus changes so that navigating between views behaved correctly for assistive technology. The project was merged into React Router starting with version 5, and its accessibility techniques were folded into that library, leaving Reach Router itself deprecated.
Overview
Reach Router grew out of a frustration with how most client-side routers in the React ecosystem treated accessibility as an afterthought. Where earlier routers focused primarily on matching URLs to components, Reach Router was designed from the start around the question of what happens to a keyboard or screen-reader user when the visible content changes without a full page reload. It shipped automatic focus management, so that navigating to a new route moved focus to the new page's heading rather than leaving it stranded on a link that no longer made sense in context. Mechanically, Reach Router used a ranking algorithm to match the current URL against a tree of route definitions, picking the most specific match rather than requiring routes to be declared in a particular order. This made nested and dynamic routes easier to reason about than in some contemporary routers, where route order affected which component rendered. It exposed a small set of components, `Router`, `Link`, and `Redirect`, along with hooks like `useParams` and `useNavigate` for reading route state and triggering navigation imperatively. Compared to its main contemporary, React Router, Reach Router took a narrower, more opinionated stance: fewer configuration options, a stronger insistence on accessible defaults, and a simpler mental model for nested routes. It did not attempt to support server-side rendering or non-React environments, positioning itself specifically as an accessible client-side router for single-page React apps rather than a general-purpose routing solution. In practice, teams adopted Reach Router when accessibility compliance was a hard requirement and they did not want to hand-roll focus management on top of another router. It saw use in government and enterprise applications where WCAG conformance was mandated, as well as in projects maintained by developers who valued its simpler API surface over React Router's broader feature set. Reach Router's most consequential limitation turned out to be its own success: its ideas were good enough that the React Router maintainers absorbed them directly, merging the two projects starting with React Router version 5. Since that merger, Reach Router has been deprecated and receives no further updates, so any project still depending on it directly should plan a migration to a current version of React Router to keep receiving security and compatibility fixes. Continuing to run Reach Router in a production application also means missing out on newer React features such as concurrent rendering support, data loaders, and nested route conventions that React Router has continued to develop since the merger, widening the gap between the two libraries over time. Teams auditing a dependency tree for unmaintained packages should treat a direct Reach Router dependency as a signal to schedule a migration rather than as neutral technical debt.
Key Features
- Automatic focus management moves focus to new content after route changes
- Ranking-based route matching picks the most specific match regardless of declaration order
- Small component API centered on Router, Link, and Redirect
- Hooks for reading route parameters and triggering imperative navigation
- Built-in support for nested, relative routes without extra configuration
- Designed to meet accessibility guidelines by default rather than through opt-in props

Reach for long-context prompting when the relevant material is small, stable and fits comfortably in the window; reach for retrieval when the corpus is larger than the window, changes often, or must be filtered per user. The decision is driven by corpus size, update rate and cost per request, not by which approach is newer.
