Learn Vert.x - Reactive microservices with Java (Udemy.com)

This course uses Vertx 4.+ and hasn't been updated to Vertx 5. I completed the course using the latest version and found that POM file dependencies had changed between versions and some of the commands used had been deprecated or removed completely, especially around WebSockets and Postgres. This made following the course more difficult as I had to spend time looking at API documentation for the classes, methods etc. The instructor also jumps around a bit within each video which meant I was constantly stopping and starting the videos when trying to follow along or ensure I understood what was being done. That aside the course was useful introduction into the subject and has given me a better understanding of the framework, which is what I was looking for. Access to the GitHub code was useful as a way to see what was being covered, however for those sections where the previous sections code was used as the basis for the next section it may be beneficial to version the code to match the sections, as the github code is really the completed course code.

I liked the clear explanation of things, but the course focused more on the implementation part instead of theory. I had to use GPT + other sources to learn how the event loop internally works, how the messages are propagated within the engine, the difference between the worker threads and the event-loop threads... What happens in the background (CPU/Heap) when the task is enqueued on the event loop internal task queue (which also wasn't mentioned). But overall, I liked the explanation.

Coming from a background of working with Quarkus for 2 years and Spring for a several years before that, this was helpful in seeing a bunch of the underlying functionality that my team has missed. There's a ton of content to this course and it definitely covers a ton of basis. The struggle in some sections is how in depth it is in the basics and that is great for fundamentals. What I would want to see some heavily advanced usages or an end goal of an application eco system built of all these small parts. Thanks for this course!

In my case, I was interested in understanding a little more how "magic" worked within Quarkus, but I was pleasantly surprised to discover a "toolbox" for some things where I prefer or need to have more control. My 5 stars for this course as a sufficient introduction to reactive microservices and the wide range of applications of Vert.x.

The course is really well paced, though feels slow at first. Sessions are perfectly placed together and constantly touch upon side topics, as bonus, along with the main stream subject. The course did cover all the basic parts of Vert.x framework well with details and gotchas. I liked the way tests-cases were taken care of along with the topics, rather than throwing separate section for them.

Very good instructor with practical tips/example. Good course content. Vertx can be a very complicated framework to learn. There is very little help online and there is only one book available on Vertx. So, I'm very greatful for this course. Vertx can be very nasty and unforgiving, when it is not used properly. Couple more chapters on monitoring and worker threads for blocking operations would make the course perfect.

I am very new to Java and of course reactive programming in Java, Vert.x and Quarkus. On the client side I am familiar with JavaScript Promises and Async/Await. I found it strange there is no native Async/Await in Java so doing this course helped me change the way I needed to think about my code so I could adopt the best patterns in a non Async/Await world, while still writing Async code across the Event Bus, driven by WebSockets. So, this course ticked a number of boxes that were a bit of a mystery before I started. Thanks!

Субтитры очень плохо соответствуют произношению и сбивают с толку, когда не совсем понятно произношение. Пока курс нравится по подаче материала и структуре. Не очень подробно. В части VertX Web REST API нет запросов POST. Про конфигурации приложения нет объяснений механизма чтения и загрузки настроек.

This excelent course made easier my introduction to reactive back-end microservices programming with Vert.x. The examples were good and I suggest a quick overview of them in the beginning of the course. I also had to antecipate the Postgress setup to be able to make the project run and finally, for VS Code users, some configurations made in InteliJ were not clear. I made them in configuration files inside resourses folder of the project. Thank you!

The topics were clear and precise. Learnt a lot. BUT the only and the biggest CON of this course is that, the instructor has very bad English pronunciation. Took more time to complete the course than needed because it was hard to figure out what the instructor was trying to say. If we overlook the pronunciation then it was an awesome course.

The course was good, presenter have good knowledge of material. However there were some deprecated methods(not presenter fault) Future.future() . That is replace by Promise.promise(). I had some problem getting my vue.js to work so i just went along doing my web page in spring boot instead.Overall a great course.

I like the content. I had some problems with the volume of the course. The instructor was very soft-spoken. But I felt the course content was pretty helpful
