Local package development and deps directory

Hello everyone!

Im working on a library (similar to Petal, but the difference is that it also provides some js and css files.

So in my mix project I have the following code to let me decide when to work on the library

def palette_dep(true = _local) do
    [{:palette, path: "../palette"}]
  end

  def palette_dep(false) do
    [
      {:palette, git: "https://github.com/myorg/palette", tag: "0.1.3"}
    ]
  end

In the project package.json file I have

{
  "dependencies": {
    "palette": "file:../deps/palette"
  }
}

So then I can reference the css in the app.css doing @import "palette". So far so good…

The problem appears when I have to work locally, the reference "palette": "file:../deps/palette" is no longer valid because the library is not being compiled in the deps folder, so the css doesn’t load. I tried to change the package.json to

{
  "dependencies": {
    "palette": "file:../deps/palette"
  },
  "devDependencies": {
    "palette": "file:../../palette"
  }
}

And that works great, but it fails when I try to compile the assets in production since it seems that the esbuild/tailwing are also trying to compile devDependencies (which is odd?) and fails because "palette": "file:../../palette" doesn’t exists.

So when working locally is there any to force to compile the library in the deps directory? Or is there any guide, doc, example of building this kind of resources?

Thanks a lot!
