koajs/router

The @koa/router package is a modern, TypeScript‑native router middleware for Koa that supports Express‑style routes, named URLs, parameter validation, nested routers, host‑matching, and full type safety out of the box. It’s ideal for developers building scalable web APIs or applications with Koa who want clean, composable route definitions, explicit URL generation, and robust error handling without extra type‑definition dependencies.
