Kotlin + Helidon by Mitia Alexandrov

Let me tell you about my first experience using Kotlin with Helidon. (Trust me, its a good story!)

I was writing code and wanted to refactor it in some way. I looked at some of the menus in Intellij Idea, and I saw an option to “Convert to Kotlin” or I could use the key combination “⌥⇧⌘K” (Ctrl+Alt+Shift+K). And I love Kotlin. Hmm…

I was curious, so I switched to our Helidon SE Quickstart project, pressed the key combination mentioned above, and voilà! all of my code automatically converted to Kotlin. Then, to test the code, I went directly in the IDE and pressed the start button – and it worked! I really liked Kotlin and how easy it was to use, but I needed to try it with some other code. I decided to try it with the Helidon Quickstart project.

If you’re new to Helidon, let me give you a quick overview. Helidon has two frameworks: Helidon MP, our MicroProfile implementation, is our preferred way of creating microservices; and Helidon SE, which is our pure reactive Java set of APIs (which provides the backing for MP). We like to call SE “The Danger Zone”, since it provides you ultimate performance with no compromises. Now on to the testing. Read the complete article here.
