Monorepo: Type not resolved from another package

[soelen]

Describe the bug

Hey,

I recently found out when I publish my package the types for my icon component are missing.

This has probably something todo since I import the type from another package of my monorepo.

I suspect that this has something todo with dts or rather my missconfiguration of dts. I created a MRE in order to make an investigation possible.

I'm sorry if this is something obvious, tried to scroll through some of the issues but not luck.

Thanks in advance

If your icons package is also being published, and you're importing it into the components by using the published icons package name (with an alias mapping it to the local path during development), then there won’t be any issues.

Otherwise, you'll need to include the content under the icons path when building the package, like:

{
  "include": ["src", "../icons"]
}

This is currently a limitation of the monorepo setup, and we haven't found an ideal solution yet. My suggestion is to publish the icons package as a standalone library.
