19. decisions

20. “static” pages
Privacy Policy, Terms of Services, About Us, etc

21. not static at all
customers what to change them from time to time

22. I don’t

23. basic CMS
not a full featured monster

24. too many choices

25. High Voltage

28. ComfortableMexicanSofa

29. another ~20 projects
worth mentioning

30. it shouldn’t be a part of the framework!

31. why?

32. ERB

33. HAML

34. choice
ERB is a default

35. i18n
keeps the texts in separate YAML files

36. textile or markdown

37. basic CMS

38. CORS
Cross-origin resource sharing

39. server:
http://api.service.com AJAX calls
client:
http://example.com

40. Access-Control-Allow-Origin

41. Rack CORS Middleware
https://github.com/cyu/rack-cors

42. JSON serialization

43. business logic
should be in a model

44. as_json

45. class Meaning < ActiveRecord::Base
has_many :senses
AS_JSON = {
only: [:id, :name],
methods: [:voiceover_url],
include: {senses: Sense::AS_JSON}
}
AS_JSON_SHORT = {only: [:id, :name]}
def as_json(opts = {})
super opts.merge(opts.delete(:short) ? AS_JSON_SHORT : AS_JSON)
end
end
# controller
def index
render(json: collection.to_json(short: true))
end

46. representation
should be in a view

47. Jbuilder
https://github.com/rails/jbuilder

48. JSON Builder
https://github.com/dewski/json_builder

49. class MeaningsController < InheritedResources::Base
respond_to :json
actions :index
end
# app/views/meanings/index.json.json_builder
meanings collection do |meaning|
id meaning.id
name meaning.name
end

50. think

51. user authentication

52. OmniAuth

56. Push Technologies Overview
http://astrails.com/blog/2012/10/2/devcon-2012-real-time-web-slides

57. dumb server
no business logic, no persistence, direct relay

58. notify push server
Rails push server
create/update content send updates
client client
client
client
client
client

59. hosted solutions
pusher, pubnub, hydna, and others

60. channels and messages

61. pubnub = Pubnub.new(... keys and auth...)
pubnub.publish(
message: "some-message, preferably JSON",
channel: "some-channel-name, preferably secret token"
)
# somewhere on a client side ...
PUBNUB.subscribe({
channel : "some-channel-name, preferably secret token",
callback : function(message) {
console.log("we've got a message", JSON.parse(message))
}
});

62. config.push = :pubnub
config.push_auth = {...}
Rails.push.publish(channel: @post.token, json: @comment)
# somewhere on a client side ...
$(window).on("push", function(e, channel_name, message) {
console.log("new message", channel_name, message);
});

63. pagination

64. will_paginate vs. Kaminari

65. infinite scroll

66. abstraction

67. a part of the framework

68. save a lot of time
