LET’S STICK WITH THE TERMS
REFACTORING IS THE PROCESS OF RESTRUCTURING EXISTING COMPUTER CODE WITHOUT CHANGING ITS EXTERNAL BEHAVIOUR
EXTERNAL BEHAVIOUR IS THE BEHAVIOUR OF AN ENTITY AS SEEN AT ITS INTERFACE, WITHOUT SEEING INSIDE THE ENTITY OR ITS OTHER INTERFACES
WHAT’S MAKE ME PROUD
REFACTORING IS A CORE PART OF
THE RUBY IDEOLOGY
WHAT’S MAKE ME SAD
FOR THE PAST THREE YEARS THERE WAS ANY NEW THING
▸ the tools ecosystem has been slowdown
▸ speakers talks about the same things over & over
▸ the language doesn’t bring anything awesome
(get ready for the built-in pry on 25.12.2016 🎉😒😒😒)
RUBY IN A COMA
John Doe
LONG STORY SHORT
HOLD ON, DON’T BE ANGRY
COMA IS NOT THE ENDAFTER ALL THIS LEMON CAN GIVE US A MONEY FOR A FEW YEARS
JUST DON’T PUT ALL YOUR EFFORT ON IT. OTHERWISE…
WHEN YOU ACCEPT THIS, ONE THING WILL HAPPEN*
YOU WILL USE THE LANGUAGE LESS OFTEN…
WHEN YOU ACCEPT THIS, ONE THING WILL HAPPEN*
… BUT MUCH MORE EFFECTIVELY
*THE EFFECT DOES NOT REPRODUCES ON SHIT CODERS
YOU START DISCOVER ONE INTERESTING SIDE-EFFECT
YOUR RUBY CODE REFACTORS WITHOUT RUBY
PHASE 0
YOU START NOTICING THAT FRONTEND IS NOT A TOY
NOWADAYS
PHASE 1 - CSS
PHASE 1 - CSS
FIRST THEY IGNORE YOU, THEN THEY LAUGH AT YOU, THEN THEY FIGHT YOU, THEN YOU WIN.
Mahatma Gandhi (a senior js developer)
PHASE 2 - JS
PHASE 2 - JS
IT WAS A RADICAL CHANGE IN A PAST FEW YEARS
2010 NOWADAYS
PHASE 2 - JS
IT STEALS:
▸ Views
▸ Presenters
▸ Helpers
▸ Controllers
▸ Routing
▸ Translation and localization
PHASE 2 - JS
ALL YOUR VIEWS IS:
PHASE 2 - JS
RUBY IS JUST A THIN LAYER OF AUTHENTICATION + PERSISTENCE
PHASE 3 - AUTHENTICATION & PERSISTENCE
DATABASES ARE NOT MYSQL ANYMORE
▸ JSON is a part of any adequate database
▸ Row Level Security - your database itself manages an
authorisation logic
▸ Database validation functions
TO SUM UP
EVEN IF RUBY IS STACK IN 2012, THE OUTSIDE WORLD CAN MAKE IT BETTER
FOR THE LAST WORD
THANK YOU
