Hello guys. How hanami handles routes with subdomains? I'm working on a project with a subdomain per client and I didn't figure out how to handle this using Hanami. In Rails I found some references:

# application_controller.rb
class ApplicationController < ActionController::Base
  protect_from_forgery with: :exception
  before_action :ensure_subdomain

  def current_blog
    @current_blog ||= Blog.find_by(subdomain: request.subdomain)
  end
  helper_method :current_blog

  private

  def ensure_subdomain
    redirect_to root_url(subdomain: :www) unless current_blog.present?
  end
end

# routes.rb
Rails.application.routes.draw do
  constraints(SubdomainRoutes) do
    resources :blogs, only: [:new]
    root 'welcome#index'
  end

  constraints(!SubdomainRoutes) do
    resources :blogs, except: [:index, :new] do
      resources :posts
    end
    root 'blogs#show'
  end
end

# subdomain_routes.rb
class SubdomainRoutes
  def self.matches? request
    case request.subdomain
    when '', 'www'
      true
    else
      false
    end
  end
end
