As per the documentation: Flux is a stream which can emit 0..N elements: Flux<String> fl = Flux.just("a", "b", "c"); Mono is a stream of 0..1 elements: Mono<String> mn = Mono.just("hello"); And as both are the implementations of the Publisher interface in the reactive stream. Can't we use only Flux in most of the cases as it also can emit 0..1, thus satisfying the conditions of a Mono? Or there are some specific conditions when only Mono needs to be used and Flux can not handle the operations? Please suggest. In many cases, you are doing some computation or calling a service and you expect

The current milestone (M4) documentation shows and example about how to retrieve a Mono using WebClient : WebClient webClient = WebClient.create(new ReactorClientHttpConnector()); ClientRequest<Void> request = ClientRequest.GET("http://example.com/accounts/{id}", 1L) .accept(MediaType.APPLICATION_JSON).build(); Mono<Account> account = this.webClient .exchange(request) .then(response -> response.body(toMono(Account.class))); How can we get streamed data (from a service that returns text/event-stream ) into a Flux using WebClient? Does it support automatic Jackson conversion?. This is how I did

I've come across Mono.defer() in some Spring webflux code I looked up the method in the docs but don't understand the explanation: "Create a Mono provider that will supply a target Mono to subscribe to for each Subscriber downstream" please could I have an explanation and an example. Is there a place with a bunch of Reactor example code (their unit tests?) that I might reference. thanks It is a bit of an oversimplification but conceptually Reactor sources are either lazy or eager. More advanced ones, like an HTTP request, are expected to be lazily evaluated. On the other side the most simple
