As long as coroutines are experimental i would not recommend. But If youchose to go with coroutines without rx i would love to hear about the experience and you should definately write a blog about it 🙂

experimental doesn't mean alpha https://stackoverflow.com/questions/46240236/can-experimental-kotlin-coroutines-be-used-in-production?rq=1

my opinion is that coroutines allows you to reason about asynchronous code in a synchronous manner, likewise JMM allows you to reason about java memory model

for some case it is interesting

for instance the classic database acquire/use/release connection

I find it much more natural using the try/catch/finally construct than with Rx

writing a non blocking parser also is an interesting case: if you have ever written a parser, you find it much more natural to reason about parser in a synchronous manner than in an non blocking manner

both are state machines

but with coroutines for me it’s easier to reason about it

here is an example of an HTTP parser

written with vertx and coroutines

https://github.com/vert-x3/vertx-lang-kotlin/blob/master/vertx-lang-kotlin-coroutines/src/main/kotlin/example/Example.kt#L203

you can compare it to the Netty HttpRequestDecoder

(which is much more complex and complete of course that’s an example)
