How would you do the following with Kotlin, Spring WebFlux + Kotlin Coroutines in a reactive Way:
- Extract body (json) from ServerRequest.
- Load a (template) ClassPathResource (json) , do String replacements with values extracted from the request?

- Would a Mono be sufficient with a single map operation on the whole string?

- Under the assumption it’s not a ClassPathResource but some expensive DiskIO:
Would it make sense to Tokenize the File to a Flux/Flow<String>

Don't sound like you can parallelize anything, so a Mono should be fine.
That's more of a Reactor/reactive question than a webflux/coroutines thing.
You probably want to read the file on the ioscheduler and process it on the computation scheduler if it's a large file so possibly two functional Monos.
