Agenda

  • Reactive Spring (Juergen Hoeller, Josh Long @ Pivotal)

Spring Framework 5 is here ! It introduces the Spring developer to a growing world of support for reactive programming across the Spring portfolio, starting with a new Netty-based web runtime, component model and module called Spring WebFlux, and then continuing to Spring Data Kay, Spring Security 5.0, Spring Boot 2.0 and Spring Cloud Finchley. Sure, it sounds like a lot, but don’t worry! join us, your guides, Spring co-founder and Spring Framework lead Juergen Hoeller and Spring developer advocate Josh Long, and we’ll explore the wacky world of Reactive Spring together.

  • Multiplatform development with Kotlin (Dmitry Jemerov @ JetBrains)

In Kotlin 1.2, we’ve added support for developing multiplatform projects. Multiplatform projects allow you to reuse the business logic written in Kotlin between all the components of your application – backend code on the JVM, frontend code in JS, and also mobile apps. The common code is compiled for all platforms and can access platform-specific implementations of APIs and libraries. The platform-specific parts are also written in Kotlin and have access to the full set of features of the corresponding platform.

  • Cool after-party!!!

Agenda

  • Do you really need reactive Spring? (Oleh Dokuka @ Levi 9, Igor Lozynskyi @Ciklum/Zoomdata)

Reactivity – is a buzzword. Nowaday’s market talks about reactivity. Vert.x, Akka, what else? Right – recently Spring Framework introduced new module called WebFlux, which allows building Reactive Application using traditional Spring features. But do we really need that module, will it help us in our every-day job, will it in solving our problems? What else is hidden behind that? All that stuff will be discussed during the talk and finally, we will get an understanding whether starting/migrating your current project with/to Reactive Spring worth it.

JUnit 5 / Project Reactor (April 13)

April 1st, 2017 1 comment

We are happy to announce our next JUG UA meeting. Our partner EPAM provides everyone with a possibility to join this event online.

Date: April 13, 19:00 – 22:30 (registration from 18:30)
Venue: “Olympic Hall – Vokzalnaya”, Vasylia Lypkivskoho St, 3, Kyiv

Agenda

  • JUnit 5: The Rise of Jupiter (Yaroslav Yermilov, @EPAM) (slides, src, video)
The planet Jupiter (5th! in the Solar System) needs 11 years to make one complete orbit around the Sun. So do JUnit needs 11 years to get a new major release, which means it’s going to be really huge.
Milestone 3 is already available and GA is scheduled on Q3 2017, so now it’s the best time learn and discuss how automating testing is going to look like very soon.
In this talk we will go through JUnit 5 changes and see how they will influence test code we write. Also we will discuss JUnit 5 architectural approach, how it can be extended and how it turns JUnit from test framework into test platform.

.

During the meetup, we are going to overview Project Reactor in depth and trying to understand how to use correctly given functionality and rebuild imperative web application to reactive one.
Agenda:
1. Project Reactor overview.
2. Imperative Application analyzing (2 pages web application with the Gitter integration and plain DB for event logging)
3. Test Refactoring
4. Application refactoring
