Questions tagged [spring-webflux]

Spring Framework 5 includes a new spring-webflux module. The module contains support for reactive HTTP and WebSocket clients as well as for reactive server web applications including REST, HTML browser, and WebSocket style interactions. WebFlux can run on Servlet containers with support for the Servlet 3.1 non-blocking I/O API as well as on other async runtimes such as Netty and Undertow.
