Reactive Programming Course

Learn with Oleh Dokuka, Java Champion and author of "Reactive Programming in Spring"

The goal of this course is to learn Project Reactor from A to Z as well as to understand how to apply it in production. During the journey we will learn the very essentials of reactive programming; the most common as well as the most advanced operators and their behaviors; the application of reactive to solve common microservices problems; refactoring to and development of reactive applications using Project Reactor and Reactive Spring.

This course has 3 fundamental parts: Reactive Basics which is aimed to explain the importance of reactive programming and its fundamentals such as functional programming; Project Reactor A-Z aimed to explore one of the most popular reactive programming libraries; Reactive in Action is aimed at applying the reactive approach in building microservices applications.

The Reactive Programming is an intensive 4-day course, written and taught by Java Champion Oleh Dokuka, author of the book Hands-On Reactive Programming in Spring 5.

During the training, you will always get a chance to try out what you have learned in carefully thought out exercises. This will help you understand and quickly internalize what you have just learned.
