Download a folder as a zip file

[hadim]

Would be nice to be able to download a folder. The Jupyter server would generate an archive of the folder (zip is in the Python standard library so no extra deps to add).

• An extension already exist (https://github.com/data-8/nbzip) but I would love to see it integrated to the Jupyter server.
• See also this issue about it: Why Jupyter Notebook does not allow downloading folders? #3092

Should I open a ticket on the jupyter_server repository instead of here?

Once this feature has been integrated, adding a button on JLab and the notebook should be easy.

(if core devs agree about it, I would be happy to submit a PR)

I think this is the right way to go about it: implement in the server first (and for now most people are using the notebook server, so this is the right place to do it, though probably a ticket should be opened in the jupyter server repo as well to keep track of parallel development).

Ok and it looks like I am not the only one requesting this: berkeley-dsep-infra/nbzip#19

Will open a ticket on the server repo.

Here is a first attempt: https://github.com/hadim/jupyter-archive

The backend is working but not the frontend yet.

For the backend, I am trying to set up tests but I can't get the extension to be discovered during runtime: https://github.com/hadim/jupyter-archive/blob/6ddfeb56ebeb59dc99f5a21fd45ccdea8d2fefb6/jupyter_archive/tests/test_archive_hanlder.py

The plugin works now.

I am ready to integrate the plugin into JLab and the notebook server but I will need some guidance jupyterlab-contrib/jupyter-archive#2
