In the end of last year, our Community Spotlights were quite focused on new add-ons published to Directory. It has been really active on that front lately as well, but this time, let’s concentrate on some of the most interesting articles and examples you have recently created.
MVP in Vaadin Spring applications
For the German speaking audience, there is again some quality content available. Dr. Stefan Reisner shares his ideas of how to use MVP pattern with Spring based Vaadin applications.
Vaadin Spreadsheet to replace Excel on your workstations?
Michael Kanis shares his experiences of using Vaadin Spreadsheet. This article is also in German, but it traslates well with Chrome to English. The interesting part in his solution is that he actually packages the whole Vaadin app as an executable JAR file for local usage. This way can replace an old Excel based solution directly with Vaadin Spreadsheet. Naturally this kind of solution also has a lot of potential to add more advanced features in the future using a real development environment.
Petstore example using Spring Boot and Vaadin
Do you remember the iconic Java EE Petstore reference application and its Spring counterpart? Igor Baiborodine has done a super cool re-implementation of Petstore with a Spring based backend and modern Vaadin UI. In case somebody is asking for a larger Vaadin reference application, this is definitely my answer in the future.
Using jOOQ from Vaadin apps
Peter Kudela has set up an example that uses jOOQ for database access and a Vaadin app that uses the jOOQ service to access the data. Lukas Eder, the founder of the jOOQ project, already gave some insights for the database integration, but if you like both jOOQ and Vaadin, join Peter to develop the example further!
More Vaadin in Kotlin stuff
A Vaadin user, book author and a well known Vaadin advocate, Nicolas Fränkel, got recently interested in an alternative JVM language called Kotlin. Last year we already discussed about Vaadlin, a tool by Sergei Egorov, to help Vaadin usage from Kotlin applications. A recent article by Nicolas discusses just the usage of raw Kotlin, but integrates it with his old favourites, Spring Boot and Vaadin.
