Introduction My friend, Dmitry Aleksandrov, has been very generous in giving me a copy of his Helidon book, which he co-authored with Dmitry Kornilov and Daniel Kec. Since I was interested in learning about Helidon, I decided to read this book and see what approach it takes to develop Java applications, as opposed to Spring Boot. The book is called Beginning Helidon, and it’s a very good introduction to this framework.
