An Introduction to the Vert.x framework
- 1. OSCON An Introduction to the Vert.x framework Wednesday, July 24, 13
- 2. Hi Folks! I’m Nate @zznate http://github.com/zznate Wednesday, July 24, 13
- 3. So what is Vert.x? Wednesday, July 24, 13
- 4. “...lightweight high- performance application platform for the JVM...” Wednesday, July 24, 13
- 5. “...for the JVM” Wednesday, July 24, 13
- 6. The JVM - mature concurrency model - very stable - heterogeneous Wednesday, July 24, 13
- 7. But most importantly... Polyglot support! Wednesday, July 24, 13
- 8. You can do a lot in 40 minutes... Wednesday, July 24, 13
- 9. http://vertx.io (scroll down) To follow along, see: https://github.com/vert-x/vertx-examples Wednesday, July 24, 13
- 10. “Web apps” Wednesday, July 24, 13
- 11. Wednesday, July 24, 13
- 12. Wednesday, July 24, 13
- 15. "We need to make configuration as easy as possible so expensive tools are not needed." Wednesday, July 24, 13
- 16. Said no enterpirse software company ever. Wednesday, July 24, 13
- 17. JDBC Module Config: { address : "com.bloidonia.jdbcpersistor" driver : "org.hsqldb.jdbcDriver", url : "jdbc:hsqldb:mem:test", username : "someuser", password : "somepass", } https://github.com/timyates/mod-jdbc-persistor Wednesday, July 24, 13
- 18. “New [Java | jvm-language] Framework!!” Wednesday, July 24, 13
- 20. But Vert.x was different. Wednesday, July 24, 13
- 21. ...for the JVM Wednesday, July 24, 13
- 22. Mature concurrency model - vert.x is based on the Reactor pattern http://en.wikipedia.org/wiki/Reactor_pattern Wednesday, July 24, 13
- 23. Platform Stability - HTTP, HTTPS, TCP, SSL - clients and servers - All netty 4.0 based http://netty.io/ Wednesday, July 24, 13
- 24. Homogenous - file system API - data-driven event bus Wednesday, July 24, 13
- 25. Polyglot - Container modules - currently supports: JavaScript, Ruby, Python, Groovy, Scala, Wednesday, July 24, 13
- 28. Event Bus - simple, distributed peer-to- peer - pub/sub or point-to-point - local or distributed** - ‘data only’ with limited number of types Wednesday, July 24, 13
- 29. Event Bus ... but it’s a good idea to use JSON! (completely language agnostic - we are building services and decoupling!) Wednesday, July 24, 13
- 30. “local or distributed” BONUS: EventBus can extend directly to the browser http://vertx.io/core_manual_java.html#sockjs-eventbus-bridge Wednesday, July 24, 13
- 32. { address : "com.bloidonia.jdbcpersistor" driver : "org.hsqldb.jdbcDriver", url : "jdbc:hsqldb:mem:test", username : "someuser", password : "somepass", } Wednesday, July 24, 13
- 33. Module Benefits - encapsulation - distributability - dynamic - structured Wednesday, July 24, 13
- 34. Encapsulation - classpath and dependency - classloader isolation (but multiple instances of the module will share classloaders) Wednesday, July 24, 13
- 35. Distributability pushed to/loaded from: - file system (contained or shared) - maven central - bintray http://vertx.io/mods_manual.html#how-vertx-locates-modules Wednesday, July 24, 13
- 36. Dynamic - automatically downloaded and installed - loaded/unloaded at runtime Wednesday, July 24, 13
- 37. Structured - minimalistic descriptor syntax - sub-modules (can be thought of as "this module 'deploys' these modules" directive) Wednesday, July 24, 13
- 38. Running a module and providing it’s configuration Wednesday, July 24, 13
- 39. Modules and Concurency - Worker (blocking) - Event loop (non-blocking) Wednesday, July 24, 13
- 40. Worker Modules - single or multi-threaded - useful for legacy APIs (ex. JDBC) Wednesday, July 24, 13
- 41. Event Loop Modules - control number of instances - instance per core is ideal Wednesday, July 24, 13
- 42. Modules (best for last...) Wednesday, July 24, 13
- 43. Dog food-ing FTW: Language runtimes are all module based Wednesday, July 24, 13
- 44. Developer friendly Wednesday, July 24, 13
- 45. Polyglot (cont’d) Wednesday, July 24, 13
- 46. JavaScript - Rhino - DynJS: invokeDynamic based implementation http://dynjs.org/ https://github.com/vert-x/mod-lang-dynjs Wednesday, July 24, 13
- 47. Simple Programming Model - just don’t block the event loop! - reactor pattern - worker delegates http://en.wikipedia.org/wiki/Reactor_pattern http://vertx.io/core_manual_java.html#writing-verticles Wednesday, July 24, 13
- 48. Provides most common services - HTTP/HTTPS - TCP/SSL - SockJS - File system access (includes sendfile() wrappers) Wednesday, July 24, 13
- 49. Build It: Maven - archetype integration - plug-in for launching/running http://vertx.io/maven_dev.html Wednesday, July 24, 13
- 50. Build It: Gradle - template project to clone http://vertx.io/gradle_dev.html Wednesday, July 24, 13
- 51. Test It! - JUnit integration utilities - Container and IDE integration (IntelliJ and Eclipse) Wednesday, July 24, 13
- 52. Summary - General purpose application platform - Polyglot development - Asynchronous APIs Wednesday, July 24, 13
- 53. Vert.x: Simple. Not Simplistic. Wednesday, July 24, 13
