:asset-path

A path to :output-dir relative to your web server's root, if not already specified as such. Only required when :optimizations is :none and :main is set, because the generated :output-to file will then need to load other parts of the build at runtime.

:output-to "resources/public/main.js"
:output-dir "resources/public/js/compiled/out"
:asset-path "js/compiled/out" ;; <--- relative URL of output-dir
