Spring WebFlux & Reactor Core
Build reactive REST APIs using Spring WebFlux, working with `Mono` and `Flux` from Reactor Core.
Reactive Web with Spring WebFlux
Welcome to Spring WebFlux! This framework is Spring's answer to building reactive, non-blocking web applications.
Unlike traditional Spring MVC which uses a servlet-based, blocking model, WebFlux is designed for concurrency and high throughput with fewer threads.
It's perfect for microservices and applications needing to handle many concurrent connections efficiently.
Diving into Reactor Core
At the heart of Spring WebFlux lies Reactor Core. Reactor is a reactive programming library that implements the Reactive Streams specification.
It provides two key types for handling asynchronous data streams:
Mono: For sequences of 0 or 1 item.Flux: For sequences of 0 to N items.
These types represent publishers that emit data, which subscribers then consume.
