How to share private code between projects?

Questions / Help
1

I want to share code between my projects by creating a library. Once I’ve create a library, how will I go about adding it to my projects?

If I upload it to gitlab to a private repository, will this be possible?

Or if I keep it locally, how will I include it into each of my projects?

Are there other ways?

We put our projects in an umbrella app. There are pros and cons. Perhaps simplest way…

If I upload it to gitlab to a private repository, will this be possible?

Yes, using the :git options: mix deps — Mix v1.16.0 (see also mix deps.get - Error fetching private repo on GitHub using :github option · Issue #3422 · elixir-lang/elixir · GitHub)

Or if I keep it locally, how will I include it into each of my projects?

Using the :path options mix deps — Mix v1.16.0 (see example at elixir - using a package locally with hex.pm - Stack Overflow)

Are there other ways?

How can I use that with a private repo?

Per https://github.com/elixir-lang/elixir/issues/3422, this should work:

{:app_name, git: "git@github.com:YOUR_ACCOUNT/app_name.git"}

assuming you have SSH keys set up to connect to your private repo.
