Spine::Engines
Starting point for your Rack application and its configurations.
Installation
To install it, add the gem to your Gemfile:
gem 'spine-engines'Then run bundle. If you're not using Bundler, just gem install spine-engines.
Usage
Define your application and configuration:
# lib/my_app/application.rb
module MyApp
module Application
extend Spine::Engines::Application
extend self
# Add loaders
loaders << Spine::Engines::Loaders::LoadPaths
loaders << Spine::Engines::Loaders::EnvironmentConfiguration
loaders << Spine::Engines::Loaders::Initializers
# Add extensions
extension Spine::Routing::Engine
# Add your own extra configuration
def active_record
::ActiveRecord::Base
end
end
endDefine your shared configuration between environments. You can define
environment specific configurations in config/environments/evironment_name.rb.
# config/environment.rb
require File.expand_path('../boot', __FILE__)
environment = ENV['RACK_ENV'] || 'development'
Bundler.require(:default, environment)
require File.expand_path('../../lib/my_app/application', __FILE__)
MyApp::Application.configure do |config|
config.environment = environment
config.root = File.expand_path('../..', __FILE__)
config.load_paths! %w(
lib/my_app/**/*.rb
)

MyApp::Application.initialize!Add Bundler to boot:
# config/boot.rb
require 'rubygems'
# Set up gems listed in the Gemfile.
gemfile = File.expand_path('../../Gemfile', __FILE__)
begin
ENV['BUNDLE_GEMFILE'] = gemfile
require 'bundler'
Bundler.setup
rescue Bundler::GemNotFound => e
STDERR.puts e.message
STDERR.puts "Try running `bundle install`."
exit!
