@clean-fish-15260 @rough-dog-96241 Thanks guys. I'm considering pants strongly now. I've never seen anyone being so passionate about SBT lol. Maybe because sbt sucks hard unless you've read the documentation 20 times and have coded a plugin of your own lol. @benjw I didn't know about Pants + scalajs. I will explore more. Keep me posted if you find any resources on compile-on-change functionality. I agree about heteregenous. We're mostly a scala shop for now. I was considering creating an sbt plugin to handle other languages but I'm going to check out pants before I do anything else.
