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.

Reactive frameworks based on the Reactive Streams specification implement patterns like:

Reactive frameworks based on the Reactive Streams specification implement patterns like:

The data producer slows down serving data when there are many subscribers.

The subscriber can signal the publisher to slow down when needed.

The subscriber implements a buffer to make sure it can cope with all the data produced.

The backpressure concept could be defined as:

The backpressure concept could be defined as:

Are unidirectional channels for the server to push data to the frontend

Implement the same functionality as WebSockets: a bidirectional channel between the frontend and the backend
