Spring Tips: The Reactor Context

[@harryfernando8682]

Hi Josh , How can we use logOnNext with different maps, faltmaps in a pipeline ?

[@ganga5809]

Hi Josh, I got one example like XPathFactory instantiation XPathFactory.newInstance(), which is not thread safe hence we can use Context to store the factory here. But I can see in your examples the Context is shared among the different threads, should we have to manage ourself to make it available on the same thread only ?

Thanks! Keep posting :-)

Hi Josh, I don't see a lot of examples online using Reactive Websockets. Currently am using Websockets with UnicastProcessor for my chat room application. Can this use-case be dealt with RSockets or is RSockets just for intercommunication between Microservices? Pls, advise.

hi bud -check out this example. the important bit is that you need a `WebSocketHandlerAdapter,` a `WebSocketHandler`, and a `SimpleUrlHandlerMapping`. github.com/joshlong/reactive-revolution/blob/master/main/rsocket-service/src/main/java/com/example/service/ServiceApplication.java#L110 as for RSocket, well, your browser isn't going to understand RSocket by default. you can use a JS library to speak RSocket on top of WebSockets, but it's an extra layer. You could use RSocket to handle a chat application, though, absolutely. You'd also get some nice benefits including the ability to then more naturally consume that cha API from any RSocket client, headers ("metadata"), Spring Security JWT/Simple authentication , and more

@@coffeesoftware Thanks a lot. Will try them.

Hi Josh! It looks like some kind of MDC-style development. I see only logging as the appropriate need to use reactive context, nothing else.

I just had to write that comment before watching the whole video)))))

I think you're missing some interesting opportunities. Spring Data uses it for transaction demarcation. Spring Security uses it for propagation of principal information. HTH

Great video. Is this or similar on git ?
