1. A resource oriented framework using the DI / AOP / REST Triangle Version 0.1 (27 July 2013@BEAR.Sunday meetup #2)
2. Authors • Akihito Koriyama • Richard McIntyre
3. What’s BEAR.Sunday ? (1) • DI / AOP / REST centered framework DI AOP REST
4. DI • Dependency inversion principle (DIP) • Object instantiation / usage separation
5. DIP • Code should depend on things that are at the same or higher level of abstraction • High level policy should not depend on low level details
6. Object instantiation / usage separation • Don’t mix (compile / runtime ) • One time object construction DPNQJMF SVOUJNF
7. Application object graph by context • Application is single big one valuable • Change structure, not behavior $app Object i/f i/f Object i/f i/f Object Router Response JSON XM L
8. Application class

10. Ray.Di • Annotation based DI framework • Binding DSL • True DI
11. AOP • Cross cutting concern as framework function • Multi layered architecture Cache Log Auth
12. Aspects • log / cache / validation ... are aspects. • Core concern is your domain model, not aspects.
13. Binding by context • Annotate, then bind interpretation • @Api is intention. “JSON” is implement.

15. Binding by condition • @Log all DELETE method • @Auth all /admin/ path resources
16. Layering by context • MVC, Is 3 enough ?
17. Layering by context • Configurable layering over fixed callback Model Cache Form Transaction Auth Validation
18. Runtime injection by aspect • Parameter provider inject parameter. • method / parameter lookup • test friendly
19. Ray.Aop • AOP alliance standard • Injectable interceptor • Google Guice
20. REST • Everything is a resource / API • use URI, not class name
21. API driven development • API is hub • test friendly DB API Mobile Web API Cloud Mock URI API
22. Resource graph • Resource is layered

24. Layered Resource UI Mobile Web Page Resource App script App Resource Entity
25. Lazy request • ϏϡʔτϦΨʔͷϦιʔεϦΫΤετ
26. What’s BEAR.Sunday ? (2) • Resource oriented framework • no control-object paradigm • information has name
27. What’s BEAR.Sunday ? (3) • Connecting framework • DI - object to object • AOP -business logic to app logic • REST - information to information
28. Performance • Super fast • cache compiled object • cache all objects • http friendly architecture
29. Hard functionality / Soft functionality • DI for application function • AOP for runtime function
30. Scale • “model proxy” pattern • runtime injection makes db scale easy
31. What’s BEAR.Sunday ?
32. “Zen” Framework less is more.
