Composing middlewares

In a similar way that you compose plugged operations, you can also compose rack middlewares from another application.

For that, you just need to use another application. All the middlewares for that application will be added to the stack in the same order.

class HtmlApp
  include WebPipe
  
  use :session, Rack::Session::Cookie, key: 'my_app.session', secret: 'long'
  use :csrf, Rack::Csrf, raise: true
end

class MyApp
  include WebPipe
  
  use :html, HtmlApp.new
  # use ...
  
  # plug ...
end
