Add .set() to Express Router

[gtomitsuka]

Hello,

I've been working on a project and pretend using both EJS and Jade for it.
For this purpose, I thought separating stuff in multiple routers would work. However, when I tried to run it, I noticed the express.Router() does not include a router.set('view engine', 'ejs'). I am currently getting the files using fs and it works fine, but I really would like to have the advantages and simpler code that rendering with Express has.

Hi! We won't add .set and friends to routes, because it's one of the defining difference between routers (simply routing requests) and apps (having settings, methods, etc.). If you need different view engines for different parts of your project, consider simply using sub apps.

Nah, I'll fork it and then do my own implementation. Thanks anyway!

No problem 👍 let me know how the fork goes, though; the router code won't even exist in Express 5, haha.

P.S. this issue is a duplicate of #2524
