Avoid global state

As for me, having global state like this:

import "./SomeController" // import result affects as a global variable
let app = createExpressServer() // express server implicitly use "SomeController"

is not a good idea, because is handles like global variables. For example, this requries to clear metadata storage before each functional test. I think it could be better, if you made this opt-in, and add ability to explicit pass controllers, interceptors and other citizens to createExpressServer:

import SomeController from "./SomeController"
import SomeInterceptor from "./SomeInterceptor"
let app = createExpressServer(
  SomeController,
  SomeInterceptor
)

or somehow else. What do you think about it?

Global state for decorators can be avoided, if metadata information will be stored inside class function (for example in $metadata or $reflection) property. Thank you for that points, I’ll check that.
