13. A browser JS App Models Database Rails App REST + JSON API /api/posts /api/comments … Currently… JSON APIs
14. GET /api/posts/1 { "id": 1, "title": "Hello World", "body": "This is my blog's first post." "author": "Ryan Bigg" } JSON APIs

23. POST /graphql query commentQuery { comment(id: 1) { text user } } { "data": { “comment”: { text: "Great first post!", user: "Totally not Ryan” } } } Query Response GRAPHQL
24. GRAPHQL IS THE FUTURE
25. GRAPHQL IS THE FUTURE (or at least, it seems like it)
26. THE FUTURE OF RAILS Frontend + Backend apps talking over GraphQL
28. END PART ONE
29. PART TWO
31. RAILS IS ALWAYS CHANGING
32. Then… Now…
33. THE NEW SHINY IS ALWAYS CHANGING
34. JSON GRAPHQL APIs APIs
35. RAILS IS JUST A TOOL
36. APIs ARE A CONCEPT
37. THERE ARE INFINITY THINGS TO LEARN
38. FOCUS ON CONCEPTS
 NOT TOOLS
39. { name: “Ryan”, age: 30 } %{ name: “Ryan”, age: 30 } Ruby Elixir
40. h = { name: “Ryan” } if h.has_key?(:name) puts “Name: #{h[:name]}” else puts “name is not present” end Ruby Elixir fn %{name: name} -> IO.puts(“name: #{name}”) _ -> IO.puts(“name is not present”) end
41. CONCEPTS
 SPAN TOOLS

47. What is “clean code”?
48. Is this “clean code”?
49. What do other developers consider “best pracFce”?
50. Follow the code.
