12. Why do we choose TYPO3 Flow ?
Question
Answer
Being an early adopter can be risky & challenging, no ?
Yes, but why not taking risk, that’s life ?

13. Where are
we going ?

14. But first, what do we need ?
✓ A complete & flexible MVC stack
✓ A productive framework
✓ A clean code base & documentation
✓ A powerful & easy form handling
✓ A way to take care about the security
✓ A highly flexible templating system
✓ An awesome community support and feedback

15. MVC Stack & Productive Framework
Question
Did you know Extbase / Fluid ?
Answer
So you can build an MVC application with TYPO3.Flow
✓ Easy learning curve from Extbase / Fluid
✓ Add feature (security, AOP, ...) when you feel confortable
✓ AOP is complex but really powerful
✓ Security Framework is a key feature

16. A clean code base & documentation
✓ Documentation improve every day
✓ A framework is targeted for developper
✓ The code is the «real documentation»
✓ Flow has a really clean code base
✓ Take time to understand it
✓ Contributing is the best way to improve your skills

17. A powerful & flexible form handling
✓ The first prototype of medialib.tv is based on Symfony 1.4
✓ The form handling / validation was a nightmare
✓ Things change in version 2.0 and higher, but that not perfect
✓ With Flow we handle more than twelve model in a single form
✓ Complexe validation
✓ Easy to write template
✓ Consitent configuration of the validation

18. A way to take care about security
Question
How do you handle your application security ?
Answer
Joker, can you ask an other question ?
Policy.yaml
Firewall Style

19. Deny everything & Grant what’s needed

23. A highly flexible template system
✓ Fluid is good Templating System
✓ TypoScript2 give you a lots more flexibility
✓ EEL push the limit a bit higher
✓ So TS2 + EEL + Fluid = awesome templating
