Exclude directory from "h5p pack" command

Hi,

I'm new to H5P developing. At the moment I wrote my first own widget (based on the awesome) tutorial for the spectrum color picker. Everything works well, but I'm a confused how I can exclude dev-dependencies when I run "h5p pack".

So my directory structure is as follows:

h5p-widget/
├─ node_modules/
├─ scripts/
├─ package.json
├─ library.json
├─ package-lock.json
├─ README.md

Now, when I run

h5p pack -r h5p-widget

It generates a h5p file as expected but the problem is that the h5p-file also includes the node_modules directory but in my case the node_modules directory contains dev-dependencies only. So is there any way to exclude this directory?
