"remove the need to rely on :preamble for non closure dependencies." I took a stab at solving this problem with a lein plugin: https://github.com/pbostrom/lein-cljsasset It would be simple to expand to support an :externs field. Then the workflow would be that libraries declare the externs path in their project.clj, and users declare the target externs file in their environment, which they would then specify in their cljsbuild config. I'll admit it sounds a bit cumbersome still, and the whole workflow should probably be managed by a single tool. Just thinking out loud, the ideal tool would: 1) Resolve JS/CSS dependencies from classpath and concat (and minify?) to a single file for each 2) Resolve externs dependencies from classpath 3) Advanced compile all CLJS/Closure dependencies and CLJS application code with externs file(s) from step 2 4) Generate initialization/loading JS to load the JS/CSS files from step 1 5) Output a single JS file that initializes and loads your application
There would probably need to be another step in there which resolves image dependencies.
