jlpm watch is not working when making changes to Notebook codebase

[andrii-i]

Describe the bug
jlpm watch is not working when making changes to Notebook codebase. For changes to propagate, I need to call jlpm build every time

To Reproduce
Steps to reproduce the behavior:

1. Follow Setting up a development environment section of CONTRIBUTING.md (note that jlpm develop also fails but this might be due to the fact that I'm trying to change Notebook codebase, not develop a Notebook extension?)
2. Launch Notebook instance and attempt to make a change in Notebook codebase
3. Note how change would not propagate until jlpm build is called

Expected behavior
When using jlpm watch, rebuild is triggered automatically on any change

Thanks @andrii-i for reporting.

I just checked with a fresh environment on Gitpod and it seems to be working fine:

watch-command.mp4

Maybe it's an issue on how files are watched on MacOS?

Thank you @jtpio, let me look more into this, may also be a problem with my local environment

@andrii-i Can you please update or close out if the issue is limited to your local env?

Could it be due to a problematic jupyterlab-server version in your environment, c-f jupyterlab/jupyterlab_server#356?

Closing as suggested
