A rack application that allows for some rudimentary routing using procs

rack_router.rb

class Router
  attr_accessor :routes
  
  def initialize
    @routes = {}
  end
  
  def add_route(path, &block)
    @routes[path] = block
  end
  
  def call(env)
    puts "calling #{env['REQUEST_PATH']}"
    if @routes[env["REQUEST_PATH"]]
      @routes[env["REQUEST_PATH"]].call
    else
      @routes["/"].call
    end
  end
end


router = Router.new
router.add_route "/" do
  [200, {"Content-Type" => "text/html"}, [1+4]]
end

router.add_route "/something" do
  [200, {"Content-Type" => "text/html"}, ["something"]]
end

run router
