Sinatra.


I didn’t write Sinatra,
…
I just love it.


Sinatra.

require 'sinatra'

get '/' do
"Don't you hate pants?"
end


Sinatra.

require 'sinatra'

get '/homer/hate/:hate' do
"Don't you hate #{params[:hate]}?"
end


Sinatra.

require 'sinatra'

get '/homer/hate/:hate.json' do
content_type 'json'
"{'hate': '#{params[:hate]}'}"
end

get '/homer/hate/:hate' do
"Don't you hate #{params[:hate]}?"
end


Classy.


Sinatra. Classy.
require 'sinatra'
require 'rack/flash'

class ClassyApp < Sinatra::Default
set :sessions, true
use Rack::Flash

get '/' do
haml :index
end

post '/classify' do
flash[:message] = 'Your text has been classified.'
@text = "I do say, #{params[:text]}. Quite!"
haml :classify
end

end


Sinatra. Classy.


Sinatra
is not
a framework.


Framework.


Not a Framework.


Not MVC.


WDNNSP
(We Don’t Need No Stinkin’ Pattern)


Sinatra
is a
library.


Sinatra as a library.

‣A nicer Rack.
‣ Rack


Code first.

Then Sinatra.

My Awesome
Ruby Project.

speaks HTTP.
Sinatra HTTP


Do you speak HTTP?

User Rack
RestClient Sinatra


The power of
the local web.
