Ruby / Roda - Web Framework / Plugins / :middleware

Introduction

The :middleware plugin allows the Roda app to be used as Rack middleware.

In the example below, requests to /mid will return Mid by the Mid middleware, and requests to /app will not be matched by the Mid middleware, so they will be forwarded to App.

class Mid < Roda
  plugin :middleware

  route do |r|
    
    r.is "mid" do
      "Mid"
    end
    
  end
  
end

class App < Roda
  
  use Mid
  
  route do |r|
    
    r.is "app" do
      "App"
    end
    
  end
  
end

run App

It is possible to use the Roda app as a regular app even when using the :middleware plugin.

ClassMethods

`#.new(app)`

Create a Forwarder instead of a new instance if a non-Hash is given.

`#.route(&block)`

Override the route block so that if no route matches, we throw so that the next middleware is called.

RequestMethods

`#.forward_next`

Whether to forward the request to the next application. Set only if this request is being performed for middleware. attr_accessor :forward_next
