What is the preferred way to run Sinatra application? - sinatra

Question

EDIT: I got the application working using TorqueBox, so I guess the problem is related to Trinidad. However, I think my guestion about the preferred way to run Sinatra applications is still valid.
I am using JRuby, Bundler, and modular style. Here's my application code:
# myapp.rb
class MyApp < Sinatra::Base
configure :development do
register Sinatra::Reloader
end
set :server, 'trinidad'
set :environment, :development
set :logging, true
#...
end
# config.ru
require 'bundler/setup'
Bundler.require(:default)
$: << File.dirname(__FILE__)
require 'myapp'
run MyApp
# Gemfile
source 'http://rubygems.org'
gem 'rack'
gem 'sinatra', :require => 'sinatra/base'
gem 'sinatra-contrib', :require => 'sinatra/reloader'
gem 'coffee-script'
gem 'neography'
gem 'gon-sinatra'
gem 'sass'
gem 'trinidad'
What is the proper way (i.e. what kind of command) to launch my application? I'm using Trinidad, because I read that it's good solution for JRuby applications (I couldn't get TorqueBox to work). Currently I'm running my app by 'trinidad config.ru', but it throws following kind error messages:

ignoring null application
I'm using versions 1.4.1 of Trinidad and Rack, 1.7.0.preview1 of JRuby, and 1.3.3 of Sinatra.
If I run 'bundle exec trinidad config.ru', I get following errors:

Answer 1

rubygems is not loaded by default (at least with jruby --1.8) thus you'll either add require 'rubygems' on top of the config.ru as JRuby (actually JRuby-Rack) loads your app in a separate "runtime" (kind of a new ruby process but inside the same JVM process) by default.
alternatively, you might as well run using rackup -s trinidad

Answer 2

As far as the CLI command to invoke your rack configuration and application, kares is right. Using "rackup" with "-s trinidad" is the way to go if you are not using Torquebox.
As far as the Ruby command to call your application from within your rack config, here is what I do.. Not sure if this applies in your situation, if this is what you're looking for, but it will help regardless of HTTP handler:
You have MyApp, which mixes in Sinatra::Base. If you trim that class down to only configure your environment, and run "before do" and "after do" for every pageload... but not actually handle and get/post calls; then you can create specialized classes which handle certain paths in your overall application. This uses Rack::Builder's map() method...
require 'myapp'
require 'mylanding'
require 'myauthentication'
require 'myautocomplete'
require 'mysearch'
#de run MyApp
map "/" do
run MyLanding #de Catch-all, which would have "get '/*' do" in it too.
end
map "/authentication/" do
run MyAuthentication
end
map "/autocomplete/" do
run MyAutocomplete
end
map "/search/" do
run MySearch
end
Then inside each My* class, do this:
class MyLanding < MyApp
get "/*" do
..handle landing.. or see what's in the splat.
end
end
class MyAuthentication < MyApp
get "/sign/in" do
..present sign-in..
end
post "/sign/in" do
..handle sign-in..
end
end
etc...
Your sub-classes have the overall MyApp treatment of every pageload, but add routes, such that /authentication/sign/in is handled by MyAuthentication's /sign/in, for example. It's a cool way of having somewhat focused sub-applications all using the same foundation: MyApp.
