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.

Full Reactive Stack: Spring Boot 2 & Spring WebFlux

# Reactive web server

In this chapter, you’ll learn how to develop the **reactive web server**. We’ll use _Spring WebFlux_, available since Spring 5 and included from the Spring Boot 2.3 version. We'll connect to a Mongo database using its reactive driver with Spring Data, also via Spring Boot.

## Two approaches

We'll include two different web approaches within the same backend application:

1. A reactive style, using WebFlux and a MongoDB _ReactiveCrudRepository_.
2. The classical Spring Web MVC stack, using a blocking REST controller and a blocking MongoDB query.


Get familiar with the reactive web server you will be building using Spring WebFlux.
