Yes I can write an unmaintainable spaghetti mess, or I can isolate a specific business domain and write or use a library that solves this problem once and for all.
Because at the end of the day it's me who end up testing and running that code, not you.
I think you ought to reconsider what the other guy said. His suggestions were quite good because they lead to simple, idiomatic code that relies solely on the standard library.
I read matt ryer's excellent book "Go Blueprints" already. I know all that stuff. I use middlewares with complex logic, I write apps with hundreds of controllers, so with all due respect I'm not going to reinvent the wheel , each time I need to finish a project with tight deadlines.
I don't understand this Go community mindset which says that "nothing is needed but the std lib". My use case isn't Google's or anybody else's.
If the Go team wanted an idiomatic router or middleware stack well they should have provided fully featured ones in the standard lib. There are none. It means "user land".
Have you seen Negroni? It provides a simple framework which solves some the middleware problem. It doesn't use dep injection, the code is more idiomatic and you can use it with any HTTP mux/router you want.
