Thanks! The example directory is more for documentation I would say, those are available in https://geojupyter.github.io/jupytergis/lab/index.html for users to play with JupyterGIS.

So could you rename your file from examples/shapefileTest.jGIS to examples/shapefile.jGIS?

If you will to add a test that runs on the CI to make sure shapefile support does not break in time, we could add a test file in the ui-tests/tests/gis-files folder and make sure it opens there (by adding it to the list of tested files https://github.com/geojupyter/jupytergis/blob/main/ui-tests/tests/ui.spec.ts#L7)

Thanks for letting me know, this is so helpful
I'll be on it.

Thanks @arjxn-py, LGTM.
The test failure seems to be related to #162
