Hey, you could take a look at shadow-build [1]. I wrote it for exactly the use case you describe since I had that issue myself. CLJS itself will always include all source files it can find in a build which leads to your issues. shadow-build will also discover all source files but will only include the files reachable by your "main" namespaces in a build/optimize.
The documentation is a bit sparse but I'd be happy to help if you have questions. See shadow-build-example [2] for a simple example of a minimal build configuration. It is just clojure code so adding another build is either just another function or another step in the existing function. As for your other question: Yes you can fine-tune your build using the :closure-defines build option. [3] It might require a type hint though. "(when ^boolean js/goog.DEBUG (do-debug-stuff))" HTH, /thomas PS: alpha12 requires clojure-1.7 due to the .cljc support, if you don't want 1.7 yet you can use alpha9.
