tiny rack app that dynamically loads a Grape API based on the url

Grapeskin

An experimental Ruby Rack app that dynamically loads and executes correctly formed Ruby Grape APIs based on the url from an array of paths.

A Grape API looks like :

	module Ping
	  class API < Grape::API
	    format :json
	    prefix "ping"

	    get 'ping' do
	      { ping: 'pong' }
	    end
	  end
	end

A GET http://example.org/something/special request would load "Something::API" from "grapes/something/api.rb" and execute the "special" handler.

This means :

1. The Grapeskin app consumes minimal memory by itself, because the APIs and their dependencies are not preloaded

2. The Grapeskin app can support any number of APIs from one install

3. API's can installed and removed and upgraded ad hoc simply by moving files in and out of a grapes path, without restarting the server

4. Performance is less than normal because each API and its dependencies must be loaded on each request

Enjoy!
