I am building an umbrella application with a react frontend in the apps directory.
This directory is not an elixir project, it does contains webpack and react stuff.
When I start the elixir application, I receive the following error.
warning: path "apps/go_base_ui" is a directory but it has no mix.exs. Mix won't consider this directory as part of your umbrella application. Please add a "mix.exs" or set the ":apps" key in your umbrella configuration with all relevant apps names as atoms
It is working, as it is a warning, but is it possible to tell elixir to ignore this directory, and get rid of this error?
Or what kind of empty mix.exs file can I put just to do nothing?
I googled for apps" key in your umbrella configuration but found nothing relevant.
There are two keys you can set in your mix.exs in order to specify your umbrella apps: :apps_path and :apps.
:apps_path is the directory in which Mix will look for your umbrella apps. :apps can be a list of atoms with the names of the apps you want to include. If it is not set, Mix will try to find an application in every subdirectory of :apps_path.
So, if you only want to include an application called “foo” in your “apps” directory, your configuration would need to look like this:
Maybe you could also look into moving your non-Elixir applications somewhere else. I think it might be confusing for other people looking at your code who would expect Elixir projects inside your “apps” folder.
