Hey guys, I have a question regarding Arrow Fx:
how stable is it (will the API change/be deprecated)? Is it production ready in terms of quality?

[simon.vergauwen]

Hey @Pavel,

Arrow Fx is completely stable. It's built upon the KotlinX Corotuines library and its API has not changed in the last 2 years. It will most likely only see some additions in the future, or non-breaking changes with deprecation cycles if necessary

[Pavel]

thanks for the reply, I was a bit worried since the version starts with 0 (0.12.X). So you use it in your regular work project?

[julian]

@Pavel Latest release is 1.0.1.

[simon.vergauwen]

@Pavel you should use Arrow Fx Coroutines, not Arrow Fx. Check the setup guide on the official website.

oh, thanks for pointing that out, I just googled "arrow fx maven" and took the first result 😄. Also in the docs it sometimes says "Arrow Fx" and sometimes "Arrow Fx Coroutines", so I didn't notice that there is a difference, I thought it's the same thing.

[simon.vergauwen]

Arrow Fx is the overcoupling name. It has serveral modules Coroutines & STM, and in the future we might add resillience or other modules related to functional effects

[Pavel]

ah, I see, thanks for the clarification, since STM in the docs is under "Arrow Fx Coroutines Overview" I thought it's part of Arrow Fx Coroutines. I think I now understand how it's structured. Thank you 🙂 !
