Literal Controller/Presenter/Interactor implementation sample (naive), I prefer MediatR instead for most cases :) from http://www.plainionist.net/Implementing-Clean-Architecture-Controller-Presenter/

controller-presenter-interactor.cs

// "controller"
(ctx, next) => {
   let presenter = new Presenter(ctx)
   let interactor = new Interactor(presenter)
   interactor.handle(getRequestFrom(ctx))
}

class Presenter {
   constructor(ctx) { this.ctx = ctx }
   present(response) {
      let viewModel = responseToViewModel(response)
      ctx.Body = JSONSerialize(viewModel)
      ctx.Status = 200
   }
}

class Interactor {
   constructor(presenter) { this.presenter = presenter }
   handle(request) {
      // do stuff
      let response = ...
      this.presenter.present(response)
   }
}
