Koa‑tree‑router is a high‑performance HTTP router for Koa applications that uses a compact radix‑tree (Trie) to achieve up to 11× faster routing than koa‑router. It provides an Express‑style API (`router.get`, `router.post`, etc.), supports method‑not‑allowed handling, multiple middleware per route, nested route groups, and TypeScript typings, making it ideal for developers who need fast, feature‑rich routing in Koa servers.
