wouter

wouter is a minimalist routing library for React and Preact: about 2.2KB minified+gzip with zero dependencies, mimicking React Router's best practices while stripping the bulk. It offers both a hooks API (useLocation/useRoute/useParams) and a component API (Route/Link/Switch), with SSR, hash routing, nested routes and View Transitions support. Released under the Unlicense (public domain) — free for any commercial use; 7.9K stars and actively maintained. The go-to pick for small projects and embedded UIs that don't need the full data-loader stack.

1. In small projects, write routes directly with useRoute/useLocation — no top-level Router required.
2. Follow the README's migration examples to slim down from React Router.
3. Ultra-minimal cases can use the 650-byte useBrowserLocation hook alone.

• ~2.2KB gzip, zero dependencies
• Both hooks and component APIs; top-level Router optional
• SSR, nested routes, hash routing and View Transitions
• Unlicense (public domain) — use anywhere, commercially too
