Unnecessary. :code.priv_dir/1 always works, even in debug build.

Thanks. I got that from this one:

`:code.priv_dir(:my_app)` points to `priv` directory in `_build`

We are just in sync, I had the same thoughts. But it’s not the same priv directory… the one You mention is for release. While the other is being used when starting the project with mix. If You run this as a release, You can use :code.priv_dir(:my_app) # or Application.app_dir(:my_app) # They are not really equivalent! but You can choose between both. When it is used with mix, You should use priv from application root folder, because it is served by plug static. I configured a path for d…

It does point to a different directory (:code.priv_dir gives the build directory) but it does seem to work either way even with iex -S mix.

Not sure why they needed to differentiate them in that thread then. You’re right I don’t seem to need to here. Thanks.
