Kevin's Easy-to-Understand Spring Reactive Web Applications: Reactor Part 1

Direct lecture by the author of ' Reactive Programming with Spring' !

There are many books and lectures on Spring MVC in Korea. However, lectures on reactive programming based on Spring WebFlux and purely domestic books are not common.

As an instructor and author, it is not easy to easily explain a difficult technology called Spring WebFlux, and we do not yet know that Spring WebFlux is a technology that shows better performance than Spring MVC.

Kevin, who opened Kevin's easy-to-understand RxJava lecture, brings you the reactive programming series in Inflearn lectures and books after 3 years!

• Learn the basic concepts and features of reactive systems and reactive programming .
• Let's understand the difference between Blocking I/O and Non-Blocking I/O through the request processing results of a sample application in Spring MVC and Spring WebFlux style.
• Let's take a moment to understand the marble diagram through the marble diagram of Reactor Mono and Flux.

• Let's check the differences and features of Cold Sequence and Hot Sequence through pictures and code execution results.

• We use animations and example code to understand Backpressure .

• Learn about the features and usage of Scheduler, which plays a key role in managing threads.
• Let's take a look at Context, which allows you to easily share data between different execution threads.
• We will explore several techniques to effectively test and debug Reactor Sequences .

Kevin's Easy to Understand Spring Reactive Web Applications will be divided into three parts.

• Part 1 covers the concepts of reactive programming and Project Reactor, which plays a central role in Spring Reactive Web Applications.
• Part 2 only covers Operators in Project Reactor that were not covered in Part 1. Operators play the most essential role among the various parts of Reactor. In addition, we plan to open a separate lecture (Part 2) so that those who are somewhat familiar with reactive programming can learn only the Operator part separately. (As of June 2023, we are working hard on the Operator part. ^^)
• Part 3 will consist mainly of example projects that will teach you how to create a reactive web application after understanding how Spring WebFlux works. (I will open it as soon as possible after the opening of Part 2. ^^)

Q. How difficult is the lecture?

If you have experience in creating web applications using Java programming and Spring MVC, you can easily understand this course. Of course, if you watch the lecture once and listen to the parts you don't understand three or four times, and type in the code, I think you can understand this course.

Q. How is the lecture conducted?

All classes are structured so that you can understand the core concepts through lecture materials and then solidify those concepts with example code.

Q. What are the benefits of learning Spring-based reactive programming?

You can implement reactive, non-blocking applications that perform better than Spring MVC-based applications, thereby stepping up as a more competitive developer.

Q. Is the content of the lecture the same as the content in the book ‘Reactive Programming with Spring’?

Much of the content is the same as the book, but it includes additional content and example codes that were not included in the book, which has a deadline for publication.

Q. Where can I download the original example code used in the lecture?

All example codes explained in class are uploaded to github and can be downloaded from the address below.
