This document discusses the history and essentials of developing web applications. It covers how microframeworks like Sinatra and full-stack frameworks like Rails evolved from earlier technologies. Padrino is positioned as extending Sinatra by adding features like routing helpers and administration capabilities while maintaining a focus on being compact and portable. Rails influenced later frameworks but sometimes takes a detour, while Padrino and Sinatra strive for a minimal approach without unnecessary complexity.

5. THE ESSENTIALS OF
DEVELOPING
WEB APPLICATION

6. THE ESSENTIALS OF
DEVELOPING A WEB APP.
Fast
Compact
Portable

7. FAST?
Reading
Coding
Setting-up
Loading
Deploying

8. COMPACT?
Application Code
Framework Code
Dependencies
Architecture

9. PORTABLE?
Dependencies
Hosting Services
Size of Application (and Framework)

10. “Less is more.”
Ludwig Mies van der Rohe (1886-1969)

11. I MEAN
Keep developing a web app:
Fast
Compact
Portable
Then you take a delight in!

12. THE HISTORY OF
WEB APPLICATION
FRAMEWORK

13. History repeats itself

14. DRY =
Don’t
Repeat
Yourself

15. We should learn from the History

16. THE HISTORY OF
WEB APP. FRAMEWORK
(CGI, Common Gateway Interface)
Full-stack
(Minimal)
Micro-framework

17. FULL-STACK FRAMEWORK
Rails (Ruby)
Django (Python)
Catalyst (Perl)

18. FULL-STACK FRAMEWORK
Forms the big cultural sphere
Relieves your mind by hiding what you mind
You’ll never know them unless you will

19. MICRO-FRAMEWORK
Sinatra (Ruby)
Juno (Python)
Mojolicious::Lite, Amon2 (Perl)
Loli (!) -> Miku (!!!) (Haskell)
Scalatra (Scala)

20. MICRO-FRAMEWORK
Forms small/open cultural sphere
Relieves your mind by showing what you do
You should write/know only what you do

21. !!! Rails vs. Sinatra !!!

22. IMAGINE!

23. 生存戦略∼

24. SURVIVING STRATEGY
Rails doesn’t kill Sinatra
Rails doesn’t have small spin-up
Sinatra doesn’t kill Rails
Sinatra doesn’t have the order

25. your_desires << small spin-up
your_desires << fast spin-up
your_desires << the order
your_desires << scaling

26. Padrino.include?(your_desire)
# -> true

27. PADRINO
AND
SINATRA

28. PADRINO IS BUFFET

29. PADRINO IS BUFFET
Routing (Named, Multiple Format)
Helpers
Logger
Admin Apps (like Django)
Reloader (It’s smart!)

30. PADRINO IS FXXKIN’ SHIT?
Extending Sinatra through Public / Safe API
but Padrino::Routing is like a abyss ...
use (Rack Middleware)
register (Sinatra Extension)

31. Sinatra’s World?

32. THE DOMAIN OF SINATRA
= HTTP

33. KEEP IT LESS
No DBs
No helpers
No anything luxurious

34. LESS IS NOT IMPOSSIBLE
DB / ORM
View Helpers
You can use it with Sinatra!

35. ON THE SINATRA
Sinatra discovered potential / real needs
Sinatra built them
Specifications beat Conventions

36. PADRINO
AND
RAILS

37. PADRINO AND RAILS
Rails is full-stack
Padrino can be full-stack
This means you can use Padrino as not full-stack

38. RAILS IS THE INNOVATOR
Discovered many important things
Spirit of DRY, or CoC
ActiveRecord, ActiveSupport, etc.
Sometimes it makes a detour
The innovation involves pains

39. PADRINO IS THE GODFATHER

40. PADRINO IS THE GODFATHER
He glues the components of Web Applications
Test Frameworks
ORM
etc.
He guards Sinatra’s World

41. ROUTING
Rails
config/routes.rb
resource[s] (>= 3.0)
Padrino & Sinatra
HTTP Verbs (get, post, etc ...)

42. VIEW
Rails
ActionView
Padrino & Sinatara
Tilt (>= 1.0)

43. HERITAGES
Architectures and Spirits
MVC
DRY
Luxuoriousness

44. CONCLUSIONS
Padrino is on the Sinatra’s World
Rails’ heritages are behind
Padrino, Sinatra, and Rails should be all in harmony
