Off the Rails, on the way to Hanami

Ritorniamo a parlare di framework per applicazioni web con Hanami!

Hanami offre un’incredibile velocità grazie ai suoi componenti minimalisti e un approccio multi-applicazione .

Un framework così giovane sarà in grado di reggere il confronto con un titano come Rails?

1. OFF THE RAILS ON THE WAY TO HANAMI Torino Coding Society, 29 novembre 2016
2. Torino Coding Society, 29 novembre 2016 WHO AM I STEFANO PAU Web Developer @ weLaika @ramensoup7
3. Torino Coding Society, 29 novembre 2016 WHAT IS HANAMI Web Framework for Ruby LUCA GUIDI @jodosha
4. Torino Coding Society, 29 novembre 2016 WHY HANAMI • A valid alternative • Minimal and lightweight • Force the developer to write neatly • Modular approach
5. LIGHTWEIGHT Torino Coding Society, 29 novembre 2016 MINIMAL
6. MINIMAL & LIGHTWEIGHT Torino Coding Society, 29 novembre 2016 NEW PROJECT 20 40 60 80 Mb Sinatra Hanami Rails 100 (Ruby 2.3.0)
7. Torino Coding Society, 29 novembre 2016 SAME PROJECT 20 40 60 80 Mb Sinatra Hanami Rails 100 MINIMAL & LIGHTWEIGHT (Ruby 2.3.0)
8. Torino Coding Society, 29 novembre 2016 CONSTANTS AUTOLOADING Rails {development/test -> lazy loading production -> eager loading Hanami -> eager loading only MINIMAL & LIGHTWEIGHT
9. Torino Coding Society, 29 novembre 2016 MINIMAL & LIGHTWEIGHT Version: 0.1 - 0.8: • associations not implemented • manual mapping 0.9: • experimental associations • auto-mapping TOO MUCH
10. RAILS Torino Coding Society, 29 novembre 2016 DIFFERENT APPROACH THAN
11. Torino Coding Society, 29 novembre 2016 RAILS PROJECT STRUCTURE app/ |—assets/ |—controllers/ |—helpers/ |—models/ |—views/ bin/ config/ |—routes.rb db/ lib/ |—task/ test/
12. Torino Coding Society, 29 novembre 2016 HANAMI PROJECT STRUCTURE apps/ |—app1/ |—assets/ |—config/ |—routes.rb |—controllers/ |—templates/ |—views/ app2/ […] config/ db/ lib/ spec/ lib/ |—project_name/ |—entities/ |—repositories/
13. Torino Coding Society, 29 novembre 2016 HANAMI MODELS flying_trainer/ |—apps/ |—airport/ |—api/ |—dashboard/ |—lib/ |—flying_trainer/ |—entities/ |—pilot.rb |—plane.rb |—repositories/ |—pilot_repository.rb |—plane_repository.rb
14. Torino Coding Society, 29 novembre 2016 HANAMI REPOSITORIES class PilotRepository < Hanami::Repository def self.pilots pilot_db.all end def self.delete_last_pilot pilot_db.delete(pilot_db.last) end private def pilot_db new end end
15. Torino Coding Society, 29 novembre 2016 HANAMI ENTITIES class Pilot < Hanami::Entity attr_accessor :flag def flagged flag = true end def flagged? return true if flag end end
16. Torino Coding Society, 29 novembre 2016 HANAMI ACTIONS flying_trainer/ |—apps/ |—airport/ |—controllers/ |—home/ |—index.rb |—pilots/ |—index.rb |—show.rb |—delete.rb |—planes/
17. Torino Coding Society, 29 novembre 2016 HANAMI ACTIONS module Airport::Controllers::Pilots class Index include Airport::Action expose :pilots, :first_pilot def call(params) @pilots = PilotRepository.all_pilots @first_pilot = @pilots.first @some_pilots = PilotRepository.all_pilots end end end
18. Torino Coding Society, 29 novembre 2016 HANAMI VIEWS flying_trainer/ |—apps/ |—airport/ |—views/ |—home/ |—index.rb |—pilots/ |—index.rb |—show.rb |—delete.rb |—planes/
19. Torino Coding Society, 29 novembre 2016 HANAMI VIEWS module Airport::Views::Pilots class Show include Airport::View def capitalized_first_pilot first_pilot.name.capitalize end end end
20. Torino Coding Society, 29 novembre 2016 HANAMI TEMPLATES flying_trainer/ |—apps/ |—airport/ |—templates/ |—home/ |—index.html.erb |—pilots/ |—index.html.erb |—show.html.erb |—planes/
21. Torino Coding Society, 29 novembre 2016 MODULES OR MONOLITH
22. Torino Coding Society, 29 novembre 2016 MONOLITH a good solution for the first 2-3 years, but then…
24. Torino Coding Society, 29 novembre 2016 MODULAR • easy maintenance • you can start to build a monolith, but you can easily pass to a modular structure
25. Torino Coding Society, 29 novembre 2016 SOMETHING ELSE
26. Torino Coding Society, 29 novembre 2016 COMMAND LINE • hanami new project • hanami generate app action model migration mailer • hanami routes • hanami db create drop prepare any more…
27. Torino Coding Society, 29 novembre 2016 ROUTES • get '/foobars/:id', to: ‘controller#action' • post '/foobars/:id', to: ‘controller#action’ • resources :foobars • root ‘/’ any more…
28. Torino Coding Society, 29 novembre 2016 DATABASE • MySQL • PostgreSQL • SQLite3
29. Torino Coding Society, 29 novembre 2016 PRO • Minimal and lightweight • Force the developer to write neatly • Modular approach
30. Torino Coding Society, 29 novembre 2016 • Crude framework • Deep knowledge of Ruby • Poor documentation CONS
31. Torino Coding Society, 29 novembre 2016 SOME INFOS • hanamirb.org • awesome-hanami.org
32. QUESTIONS ANSWERS
33. Torino Coding Society, 29 novembre 2016 THANK YOU EVERYBODY
