16. The Base Ideas
17. Modularity Forget about fat models
18. Simplicity Framework is only tool
19. Less DSLs No magic
20. Few Conventions Come with us or against us
21. Pure Objects If you know ruby you know hanami
22. Zero Monkey-Patching Don’t think framework or language
23. Threadsafe
25. hanami != rails
26. Typical parts of web app
27. Web App Business

41. General Parts
42. hanami - base repository, CLI router - Rack compatible HTTP router for Ruby controller - Full featured and fast actions for Rack utils - Ruby core extensions and class utilities model - Persistence with entities and repositories
43. validations - Validations mixin for Ruby objects helpers - View helpers for Ruby applications view - Presentation with a separation between views and templates assets - Assets management for Ruby mailer - Mail for Ruby applications
44. Differences
45. – Linus Torvalds “Talk is cheap. Show me the code.”
46. # rack class HelloApp def call(env) [200, {}, ['Hello!']] end end
47. # hanami class HelloApp def call(env) [200, {}, ['Hello!']] end end router = Hanami::Router.new router.get '/', to: 'hello_app'
48. # sinatra class Hello < Sinatra get '/' do 'Hello!' end end
49. # hanami Hanami::Router.new do get '/' do [200, {}, ['Hello!']] end end

54. Controllers
55. Controllers: Rails class UsersController < AC def new end def send_sms end end
56. class Cats::CruelsController < AC def index end def show end end Controllers: DHH style
57. module Web::Controllers::Board class Index include Web::Action def call(params) end end end Controllers: hanami
58. Model
59. class User < ActiveRecord::Base validates :name, presence: true # ... end Model: Rails
60. Model: ROM
61. Model: hanami entity class User include Hanami::Entity attributes :name # ... end
62. Model: hanami repository class UserRepository include Hanami::Repository def find_by_name(name) query do # ... end end end
63. Utils
64. # rails class String def pluralize # ... end end # hanami module Hanami module Utils class String def pluralize # ... end end end end Utils
65. View
66. View: Rails rails view (partials?) + rails helper
67. View: Hanami hanami view (ruby class) + partial

69. Pros and Cons
70. No magic
71. Controller test describe Web::Controllers::Board::Index do let(:action){ Board::Index.new } let(:params){ Hash[] } it 'is successful' do response = action.call(params) response[0].must_equal 200 end end
72. Controller test describe Web::Controllers::Board::Index do let(:action){ Board::Index.new } let(:params){ Hash[] } it 'is successful' do response = action.call(params) response[0].must_equal 200 end end
73. Controller test describe Web::Controllers::Board::Index do let(:action){ Board::Index.new } let(:params){ Hash[] } it 'is successful' do response = action.call(params) response[0].must_equal 200 end end
74. No monkey-patching
75. Best practices
76. Modularity
77. The logic separation
78. TDD
80. TDD
81. The same type of code in the controllers
82. Not stable version
83. Missing Gems
84. WebSockets WebPack React
85. * overcome hardships
