The Slim Framework’s router is built on top of the[Fast Route](https://github.com/nikic/FastRoute)component, and it is remarkably fast and stable. While we are using this component to do all our routing, the app’s core has been entirely decoupled from it and interfaces have been put in place to pave the way for using other routing libraries. Slim框架的路由器構建在[Fast Route](https://github.com/nikic/FastRoute)組件之上，非常快速和穩定。當我們使用這個組件來完成所有的路由時，應用程序的核心已經完全與它解耦，接口已經到位，為使用其他路由庫鋪平了道路。 > 由 Laravel 組件搭建而成的微框架Lumen 路由也是基于Fast Route
