Does not work on jupyterlite - Can/will it ?

[oscar6echo]

I tried install jupyterlite_code_formatter in a custom jupyterlite deployment following the official recipe.

Locally, all works as expected.
On jupyterlite, I see the following alert window:

Can/will jupyterlite_code_formatter work in jupyterlite ?
That would be convenient !

Didn't know this exists, TIL!

I did a quick investigation, it's unlikely jupyterlite can be supported without a big rework, in order to support it, we also will need to strip out some functionalities.

I will keep this issue open for now and see if jupyterlite matures in a way that it's easily supported.

This is likely because jupyterlab-code-formatter requires a server extension to run the linters:

jupyterlab_code_formatter/jupyterlab_code_formatter/__init__.py

Lines 9 to 10 in 5d91776

	def _jupyter_server_extension_points():
	return [{"module": "jupyterlab_code_formatter"}]

It would be interesting to check if some of the linters can be run in the browser directly (for example with Pyodide). If so then the extension could be configured to provide a way to format the code in the browser directly, and could enable using it in lite.
