React Router v8, a minimal breaking changes release, debuted on June 17, 2026. This version marks ESM-only builds, default middleware, and the end-of-life for React Router v6 and Remix v2. React Router v8 now requires Node 22.22.0+, React 19.2.7+, and Vite 7+. The library has migrated to an ESM-only module with updated baselines, default middleware, and splitRouteModules as a top-level configuration option.
Middleware becoming a baseline has raised concerns for teams pulling over 50 million weekly npm downloads. Some developers are considering alternatives like TanStack Router, while React Router remains popular for its straightforward migration path.
