Golang MVC structur

I searched many sites and I saw a lot of sources in github and i haven't solution.

I created mvc website pattern in Golang:

• app
  • controllers
  • models
  • lib (All the features class/functions)
  • middleware
  • router.go
• resources
  • views
• main.go

My question is: How to inject config to have everywhere settings and other implemented class that will always be needed (like load speed single page)

One more thing(additionally): Can anyone recommend me a good material or transcribe MVC tricks idea works MVC with golang (General useful information)
