When writing Spring REST services in Kotlin, would controller functions be a typical and safe place to call runBlocking { }?

[Dariusz Kuc]

if you are using coroutines you probably should use WebFlux instead of MVC

[Dariusz Kuc]

which gives you nice interop between reactor and coroutines

[Dariusz Kuc]

so your controller functions can be suspendable

[EarthCitizen]

In my case, there is a large existing code base that is not feasible to mass-convert at this time, so I need to introduce Arrow-kt incrementally

[EarthCitizen]

Is it safe to call runBlocking() from the controller function?

[Dariusz Kuc]

as the name implies it will block

[Dariusz Kuc]

but since you are using MVC it is still blocking the threads so 🤷

[Dariusz Kuc]

so yeah it will work

[EarthCitizen]

OK …I am just trying to verify that I will not break anything

[EarthCitizen]

thanks
