Vert.x in Action: Asynchronous and Reactive Java

by Julien Ponge

Vert.x in Action teaches you how to build production-quality reactive applications in Java. This book covers core Vert.x concepts, as well as the fundamentals of asynchronous and reactive programming. Learn to develop microservices by using Vert.x tools for database communications, persistent messaging, and test app resiliency. The patterns and techniques included here transfer to reactive technologies and frameworks beyond Vert.x.Summary As enterprise applications become larger and more distributed, new architectural approaches like reactive designs, microservices, and event streams are required knowledge. The Vert.x framework provides a mature, rock-solid toolkit for building reactive applications using Java, Kotlin, or Scala. Vert.x in Action teaches you to build responsive, resilient, and scalable JVM applications with Vert.x using well-established reactive design patterns. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the technology Vert.x is a collection of libraries for the Java virtual machine that simplify event-based and asynchronous programming. Vert.x applications handle tedious tasks like asynchronous communication, concurrent work, message and data persistence, plus they’re easy to scale, modify, and maintain. Backed by the Eclipse Foundation and used by Red Hat and others, this toolkit supports code in a variety of languages.

I've got nearly everything that I've expected:
* Vert.x primer
* how Vert.x corresponds to reactive streams
* Vert.x integrations with tech that follows similar paradigms (e.g., RxJava, futures/promises, Kotlin coroutines)
* Vert.x in (the most popular) web scenarios
* Vert.x persistence
* Vert.x testing & observability
etc.

Examples are OK, the level of deep dives occasionally could have been deeper, but it's enough for a proper start. What did I miss? Well, I appreciate the last chapter (on Vert.x within containers/Kubernetes), but I'd like to see Vert.x in cloud scenarios (incl. serverless).

Do I recommend this book? Hell-yes, especially keeping in mind that it literally has no alternatives.
4.8 stars.

Good intro on Vert.x.
I didn't know anything in particular about Vertx before that. Seen a few examples, but haven't really worked with it.
This book is a great introduction to what Vertx is, how it works, and its main principles. The book has 2 parts: theory with code and examples and real working practice project. The project is quite interesting, as it's a set of microservices and I really enjoy reading and working with it. The book also includes testing for the project, including chaos testing (which is quite nice), and working on scalability and resiliency with best-in-class patterns and implementations. And, well, running Vertx project in containers (simple k8s).
Overall, I enjoyed the book and totally recommend it to all who want to know about Vertx.

Great book.
Not only you get to learn Vertx, but general concepts such as reactive programming and software resiliency are exposed, so that you can transfer the acquired knowledge to different technologies.
The examples and applications presented are also a great resource to deep dive into the technology.
I wish more technology books would be written in this style

Lots of relevant code examples, uses a bigger real world example to introduce many aspects of Vert.x like database connectivity, messaging and testing.

Generally, it's a good book to learn Eclipse Vert.x. It provides real example of chaining most knowledges together than its official website.
