Questions / Help

There’s a hook/function for edeliver which is specified in .deliver/config:

pre_erlang_clean_compile() { ....... }

Is there a hook for this moment during deploying:

-----> Preparing assets with: brunch build and phoenix.digest
-----> Compiling sources
-----> Generating release
[is there a hook for this?]
