The usual CLJS tools do not support this but shadow-cljs [1] does. Closure has a variable and property map feature that will save the names it used on one compile which can then be imported on the next compile. shadow-cljs does this automatically and as long as you don't remove the map files the naming will be stable. Sometimes due to code motion the hash of the file overall changes but that should only happen if you make bigger changes. I have been using this for a while and caching is definitely improved by this.
There is a very old blog post [2] that talks about this feature. See "Short Names Aren't Necessarily Better".
