Reactive Spring focuses on providing an understanding of the fundamental principles and technologies that are used in reactive programming. This understanding is critical to being able to diagnose, troubleshoot, tune, and perform other lifecycle activities. Geared for experienced Java developers with basic Spring experience, Introducition to Reactive Spring explores concurrent, asynchronous and reactive programming APIs and techniques using Spring. Throughout the hands-on course, students will explore reactive programming essentials, Reactive Streams and the Project Reactor APIs, as well as how these APIs are integrated into Spring. Spring 5 includes Spring WebFlux, providing a reactive programming model for web applications, as well as support for Reactive REST APIs. Students will also learn about Spring WebSocket, which assists in the creation of web applications to provide a full-duplex, two-way communication between client and server. The course also covers Spring Data, which implements database operations relying on Reactive Programming APIs. While the Spring R2DBC initiative aims to bring reactive programming to relational databases, several NoSQL databases already provide this possibility. Along with an introduction to NoSQL and the MongoDB, this courses also explores the APIs available to communicate with this NoSQL database using both blocking and reactive APIs.
