Reactive Programming Course
Learn with Oleh Dokuka, Java Champion and author of "Reactive Programming in Spring"
Using Java 17
Duration of 4 Days
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.
Prerequisites
This course is ideally suited to the professional Java programmer with at least 2 years experience, who would like to learn how to code with reactive Java.
