Using multiple extensions with custom controller

This is effectively the same as using Jellyfish::Sinatra extension. Note that the controller should be assigned lastly in order to include modules remembered in controller_include.

require 'jellyfish-contrib'
class Tank
  include Jellyfish
  class MyController < Jellyfish::Controller
    include Jellyfish::MultiActions
  end
  controller_include NormalizedParams, NormalizedPath
  controller MyController

  get do # wildcard before filter
    @state = 'jumps'
  end
  get %r{^/(?<id>\d+)$} do
    "Jelly ##{params[:id]} #{@state}.\n"
  end
end
use Rack::ContentLength
use Rack::ContentType, 'text/plain'
run Tank.new

Extension: MultiActions (Filters)

require 'jellyfish-contrib'
class Tank
  include Jellyfish
  controller_include Jellyfish::MultiActions

  get do # wildcard before filter
    @state = 'jumps'
  end
  get do
    "Jelly #{@state}.\n"
  end
end
use Rack::ContentLength
use Rack::ContentType, 'text/plain'
run Tank.new

Halt in before action

require 'jellyfish-contrib'
class Tank
  include Jellyfish
  controller_include Jellyfish::MultiActions

  get do # wildcard before filter
    body "Done!\n"
    halt
  end
  get '/' do
    "Never reach.\n"
  end
end

use Rack::ContentLength
use Rack::ContentType, 'text/plain'
run Tank.new

Extension: NewRelic

require 'jellyfish'
class Tank
  include Jellyfish
  controller_include Jellyfish::NewRelic

  get '/' do
    "OK\n"
  end
end
use Rack::ContentLength
use Rack::ContentType, 'text/plain'
require 'cgi' # newrelic dev mode needs this and it won't require it itself
require 'new_relic/rack/developer_mode'
use NewRelic::Rack::DeveloperMode # GET /newrelic to read stats
run Tank.new
NewRelic::Agent.manual_start(:developer_mode => true)

Extension: Sinatra flavoured controller

It's an extension collection contains:

MultiActions
NormalizedParams
NormalizedPath

require 'jellyfish-contrib'
class Tank
  include Jellyfish
  controller_include Jellyfish::Sinatra

  get do # wildcard before filter
    @state = 'jumps'
  end
  get %r{^/(?<id>\d+)$} do
    "Jelly ##{params[:id]} #{@state}.\n"
  end
end
use Rack::ContentLength
use Rack::ContentType, 'text/plain'
run Tank.new

Extension: Swagger API documentation

For a complete example, checkout config.ru.

require 'jellyfish-contrib'
class Tank
  include Jellyfish
  get %r{^/(?<id>\d+)$}, :notes => 'This is an API note' do |match|
    "Jelly ##{match[:id]}\n"
  end
end
use Rack::ContentLength
use Rack::ContentType, 'text/plain'
map '/swagger' do
  run Jellyfish::Swagger.new('', Tank)
end
run Tank.new
