Hi @philippjfr. This is how I would minimize the piplite.install. I just add a DEPENDENCY dictionary containing the notebook as key and its list of dependencies as value.

I will determine and test the list of dependencies for each notebook manually. If there is an automated way to test this, then please let me know.

I chose not to add the specific install in the notebook because it might overwhelm users looking at website or using notebook in normal Python environment.

According to jupyterlite/jupyterlite#379 (comment) it should now be possible to provide a direct link to a specific notebook in Jupyterlite. I.e. it should be possible to setup an automated test using Playright that each notebook can run.

For example this link works https://panelite.holoviz.org/lab/index.html?path=reference/panes/DataFrame.ipynb

Will merge this as-is for now. Might spend some time cleaning this up further. Specifically we do have pn.io.mime_render.find_imports which tries to automatically extract required imports from source code.
