5. Agenda • Neos 3.0 - Features & Changes • CQRS / ES for the Neos CR • The Neos React UI
6. Neos 3.0 Features & Changes
7. New features in 3.0 ¯\_(ϑ)_/¯ 3.0 is focused on preparing the foundation!
8. Namespace: TYPO3 -> Neos • ~50 packages in Neos\ and Flowpack\ • … >100 more in vendor namespaces
 by Core Team Members such as Ttree, Psmb,
 Yeebase, Sandstorm, Networkteam, Flownative, Sitegeist, … • A LOT of refactoring.
9. TypoScript2 -> Fusion • To distinguish the language from TypoScript,
 it was renamed to Fusion. • File endings are now .fusion (.ts2 will continue
 to work until Neos 4.0) • More refactoring.
10. Fluid becomes standalone engine • TYPO3.Fluid is now split in typo3fluid and 
 Neos.FluidAdaptor • More refactoring…
11. PHP 7.1 compatibility • Issues with PHP 7.1 especially in rendering • Soft reserved keywords: „Object“ and „Resource“ • Even more refactoring…
12. PSR-7 compliance • PSR-7 describes a set of default interfaces
 that represent HTTP requests and responses • Some refactoring is needed to implement them. • Will probably come with Flow 4.1.
13. Rethinking 
 The Neos CR CQRS and Event Sourcing
14. What is CQRS / ES?
15. CQRS and ES primer • CQRS splits the Read and Write
 sides of an application’s model.
16. Classical Layered Architecture Controller Model View Read Write
17. CQRS Command Handler Read Write Command Domain Logic / Aggregates Event Query Models Query Models Query Models Projection
18. Benefits of CQRS Well-suited for read/write 
 disparate systems
19. Benefits of CQRS Great fit for event-driven,
 unidirectional dataflow UI
 (React/Redux, anyone?)
20. Benefits of CQRS Lets you implement collaborative editing more easily 
 (avoids locking issues)
21. Benefits of CQRS Very detailed audit log by-design
 (which we currently don’t have)

30. Reducer newState = f(oldState, action) React+Redux
