Introduce Hanami::API::DSL

Feature

Introduce Hanami::API::DSL which gives the ability to other frameworks to use the Hanami::API DSL.

Example

Imagine you're building a web framework, or simply you need a routing DSL. You declare a superclass like this:

# framework.rb
require "hanami/api"

module Framework
  class App
    def self.inherited(base)
      super
      base.extend(Hanami::API::DSL)
    end
  end
end

Then in your app, you inherit from your superclass, which has now a .routes class method that can wrap all the routes. Within that block you have all the Hanami::API methods available.

 # app.rb
require "framework/app"

class MyApp < Framework::App
  routes do
    root { "Hello, World!" }
  end
end

In config.ru (for Rack web servers), you just initialize your app.

# config.ru
require_relative "./app"

run MyApp.new
