Debugging JupyterLab extensions (help/best practices/PyCharm debugger)

[asmith26]

Hi there.

I’m trying to build a JupyterLab extension. I love the PyCharm debugger, and I’m wondering how I can make use of this whilst developing my extension. Just wondering if anyone knows of any guides on how to configure PyCharm such that I can put a debug breakpoint in either my TypeScript/Python JupyterLab extension code so that it gets caught?

I think this repo provides a guide for VSCode, in particular:

• Slides: https://github.com/jupytercon/jupytercon2020-developingextensions/blob/master/slides/3-jupytercon_2020_debug_tutorial.pdf
• YouTube (possibly created by @telamonian): https://www.youtube.com/@codeepic5685/videos
  • These videos also point to https://github.com/jpmorganchase/jupyter-fs/tree/main/.vscode

I very much welcome any other pointers/links to more guides (for either PyCharm/VSode/otherwise :) )

Many thanks for any help!
