it's a legacy flag now, it used to be possible to switch between compojure and reitit, but I've deprecated compojure at this point since there's really no advantage in using it over reitit anymore
we're using this lib I wrote a while back on my team https://github.com/yogthos/lein-sass
one caveat is that nashorn is going away, so it won't work with newer versions of the jvm
I should take a look if it's possible to switch to using ringojs instead https://ringojs.org/
actually this looks more promising https://github.com/dynjs/dynjs
actually looks like there is a standalone nashorn on clojars, I added [org.bodil.openjdk/nashorn "0.1.0.2013070801"]
and it's working for me with jdk 12/clj 1.10.1
@lady3janepl I pushed out [lein-sass "0.1.10"]
, let me know if it works for you
