Small ruby web stacks When Rails is just to big

The scale of our frameworks

How much does it take to have a working ruby served web page?

require 'socket' server = TCPServer.new('127.0.0.1', 8080) loop do session = server.accept request = session.gets session.print "HTTP/1.1 200/OKrnServer: MakorsharnContent-type: text/ plainrnn" session.write "Hello world" session.close end

Rails Radiant

• The base of Rack (almost) all ruby web apps • 8439 lines of code

• Rails, great The base of Rack development (almost) all ruby platform web apps • 131990 lines code 8439 lines of of code

Merb Rails Radiant

And we still need a webserver

Radiant Rails Merb

Sinatra Rack

class HelloWorld def call(env) [200, {"Content-Type" => "text/plain"}, ["Hello world!"]] end end run HelloWorld.new

Use a Rack to Stack

use Rack::Lock use ActionController::Failsafe use ActionController::Session::CookieStore, , {:secret=>"<secret>", :session_key=>"_<app>_session"} use Rails::Rack::Metal use ActionController::RewindableInput use ActionController::ParamsParser use Rack::MethodOverride use Rack::Head use ActiveRecord::QueryCache run ActionController::Dispatcher.new

class Exaple def initialize(app) @app = app end def call(env) # edit environment status, headers, body = @app.call(env) # edit response return status, headers, body end end

use Rack::Lock use ActionController::Failsafe use ActionController::Session::CookieStore, , {:secret=>"<secret>", :session_key=>"_<app>_session"} use Rails::Rack::Metal use ActionController::RewindableInput use ActionController::ParamsParser use Rack::MethodOverride use Rack::Head use ActiveRecord::QueryCache run ActionController::Dispatcher.new

Don’t use Rack solo. ‘cause it don’t knows pages

Sinatra knows pages

require 'rubygems' require 'sinatra' get '/' do "Hello world!" end run Sinatra::Application

verb 'uri_with/:params/and/*' do # your logic logic "Your response" end

There is more

get '/' do Templates erb :index end get '/haml/:title' do haml '%h1 #{params[:title]}' end get '/builder' do builder :index end get '/css/screen.css' do content_type 'text/css', :charset => 'utf-8' sass :screen end

Helpers helpers do def pirate(name) "#{name} Arrh!" end end get '/:name' do pirate(params[:name]) end

before do request.path_info = '/foo/bar/baz' if request.path_info = '/foo/baz/bar' end get '/guess/:who' do pass unless params[:who] == 'Pirate' "You got me!" end get '/guess/*' do "You missed!" end not_found do 'This is nowhere to be found' end error do 'Sorry there was a nasty error' end
