Move Routers to Controller?

Hello, is it possible move routers rules ti contoller? ( in CI3)

What do you have in mind? The router decide which controller to call. How can it work the other way around? The only thing I can think of is a base controller that would do redirects in its constructor.

I mean put router code in Controller, beacause my routes.php is too big, and easy controll routers in controller

beacause my routes.php is too big

Why is it a problem? If you move that code in the controller it will be the same size. I don't get it.

and easy controll routers in controller

...if it's easy, then do it?
