Disclaimer: what I write here is something that is working for me, but I am not an expert, so I cannot declare this to be the best solution.
I am working on a small application that I know it will grow, so the traditional Sinatra application could be a mess when I have more than 10 routes.
So the strategy I have chosen is to create a base class called BaseController inheriting from Sinatra::Application, this base clase will handle global application settings.
#./base_controller.rb require 'sinatra/base' class BaseController < Sinatra::Base get '/' do 'Home (base controller)' end end
Then, I create one controller class for each application module, each of this controllers should inherit from my BaseController.
#/controllers/module1_controller.rb require File.join(File.dirname(__FILE__),'..', 'base_controller.rb') class Module1Controller < BaseController get '/' do 'Module 1' end end
Finally, in the config.ru file I define the base routes for each controller.
# config.ru require './base_controller.rb' require './controllers/module1_controller.rb' map '/' do run BaseController end map '/module1' do run Module1Controller end
Note: the code snippets above assume that the base_controller.rb and config.ru files are located in the root directory while every all controller files are located under «/controllers» directory.
