Reactor is the reactive library of choice for Spring WebFlux. It provides the Mono and Flux API types to work on data sequences of operators aligned with the ReactiveX vocabulary of operators. Reactor is a Reactive Streams library and, therefore, all of its operators support non-blocking back pressure. Reactor has a strong focus

Instructions for the Java Developer You can use Spring Boot in the same way as any standard Java library. To do so, include the appropriate spring-boot-*.jar files on your classpath. Spring Boot does not provides a nice way of “obtaining” Gradle when you need to build a project. It is a small script and library that you commit alongside your code to bootstrap the build process. See docs.gradle.org/current practices. Although there is nothing particularly special about Spring Boot (it is just another library that you can consume), there are a few recommendations that, when followed, make your development

specifying the type for bean references like ref("bazBean") • It is possible to use Kotlin top level functions to declare beans using callable references like bean(::myRouter) in this example • When specifying imperative way. On language side, suspending functions provides an abstraction for asynchronous operations while on library side kotlinx.coroutines provides functions like async { } and types like Flow. Spring laziness is not needed, fun handler(mono: Mono) becomes fun handler(value: T) since a suspending functions can be invoked to get the value parameter. • If laziness is needed, fun handler(mono: Mono)
