Implement a Reactive database access layer with Spring Data and MongoDB.
Write a reactive API at the controller level with Reactor's Fluxes.
Get the basics about Server-Sent Events and put them into practice.
Build a basic Angular frontend that consumes the reactive APIs.
Understand the EventSource API and how it can be linked to an RxJS Observable.
Learn how to run performance tests against blocking and non-blocking APIs under simulated slow network conditions.
Compare Blocking APIs and Reactive APIs in terms of performance, user experience, and ease of development.

ABOUT THIS COURSE

This course is your guide to using Spring Boot 2 and Spring WebFlux to create Reactive Web Applications. You will learn how to build a full-reactive system from the database (MongoDB reactive) to the front-end (Angular), using a Reactive programming strategy leveraged by Spring WebFlux, with the simplicity offered by Spring Boot 2. Beyond that though, you will be able to compare the Spring WebFlux with the standard MVC approach as well, covering the main aspects such as simplicity, performance, user experience, and more. The last part of the course ties it all up by teaching you to run the application using Docker compose. By the end of this course, you will have a great new skill for your resume and you’ll be able to build your own projects using the full Reactive stack.

These are high-quality courses. Trust me the price is worth it for the content quality. Educative came at the right time in my career. I'm understanding topics better than with any book or online video tutorial I've done. Truly made for developers. Thanks

You guys are the gold standard of crash-courses... Narrow enough that it doesn't need years of study or a full blown book to get the gist, but broad enough that an afternoon of Googling doesn't cut it.
