TABLE OF CONTENTS The essentials of developing a Web Application
The History of Web Application Frameworks Padrino and Sinatra Padrino and Rails Padrino and Others
THE ESSENTIALS OF DEVELOPING WEB APPLICATION
THE ESSENTIALS OF DEVELOPING A WEB APP. Fast Compact Portable
FAST? Reading Coding Setting-up Loading Deploying
COMPACT? Application Code Framework Code Dependencies Architecture
PORTABLE? Dependencies Hosting Services Size of Application (and Framework)
“Less is more.” Ludwig Mies van der Rohe (1886-1969)
I MEAN Keep developing a web app: Fast Compact Portable
Then you take a delight in!
THE HISTORY OF WEB APPLICATION FRAMEWORK
History repeats itself
DRY = Don’t Repeat Yourself
We should learn from the History
THE HISTORY OF WEB APP. FRAMEWORK (CGI, Common Gateway Interface)
Full-stack (Minimal) Micro-framework
FULL-STACK FRAMEWORK Rails (Ruby) Django (Python) Catalyst (Perl)
FULL-STACK FRAMEWORK Forms the big cultural sphere Relieves your mind
by hiding what you mind You’ll never know them unless you will
MICRO-FRAMEWORK Sinatra (Ruby) Juno (Python) Mojolicious::Lite, Amon2 (Perl) Loli (!)
-> Miku (!!!) (Haskell) Scalatra (Scala)
MICRO-FRAMEWORK Forms small/open cultural sphere Relieves your mind by showing
what you do You should write/know only what you do
!!! Rails vs. Sinatra !!!
IMAGINE!
ੜଘઓུʙ
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
your_desires << small spin-up your_desires << fast spin-up your_desires <<
the order your_desires << scaling
Padrino.include?(your_desire) # -> true
PADRINO AND SINATRA
PADRINO IS BUFFET
PADRINO IS BUFFET Routing (Named, Multiple Format) Helpers Logger Admin
Apps (like Django) Reloader (It’s smart!) see also: www.padrinorb.com/#introduction
PADRINO IS FXXKIN’ SHIT? Extending Sinatra through Public / Safe
API but Padrino::Routing is like a abyss ... use (Rack Middleware) register (Sinatra Extension)
Sinatra’s World?
THE DOMAIN OF SINATRA = HTTP
KEEP IT LESS No DBs No helpers No anything luxurious
LESS IS NOT IMPOSSIBLE DB / ORM View Helpers You
can use it with Sinatra!
ON THE SINATRA Sinatra discovered potential / real needs Sinatra
built them Specifications beat Conventions
PADRINO AND RAILS
PADRINO AND RAILS Rails is full-stack Padrino can be full-stack
This means you can use Padrino as not full-stack
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
PADRINO IS THE GODFATHER
PADRINO IS THE GODFATHER He glues the components of Web
Applications Test Frameworks ORM etc. He guards Sinatra’s World
ROUTING Rails config/routes.rb resource[s] (>= 3.0) Padrino & Sinatra HTTP
Verbs (get, post, etc ...)
VIEW Rails ActionView Padrino & Sinatara Tilt (>= 1.0)
HERITAGES Architectures and Spirits MVC DRY Luxuoriousness
CONCLUSIONS Padrino is on the Sinatra’s World Rails’ heritages are
behind Padrino, Sinatra, and Rails should be all in harmony
