panel compile <path> error: Could not resolve "./Calendar"

[ahuang11]

I wanted to compile: https://github.com/panel-extensions/panel-full-calendar/tree/main

panel compile src/panel_full_calendar/main.py

Running command: npm install

npm output:

added 7 packages, and audited 8 packages in 2s

1 package is looking for funding
  run `npm fund` for details

An error occurred while running esbuild: ✘ [ERROR] Could not resolve "./Calendar"

Try using the --build-dir option as described here. https://panel.holoviz.org/how_to/custom_components/esm/build.html#using-the-build-dir-option

Not sure if I'm using it correctly:

panel compile src/panel_full_calendar/main.py --build-dir src/
Running command: npm install

npm output:

added 7 packages, and audited 8 packages in 213ms

The point was for you to be able to debug it by inspecting the contents of the build_dir.

[philippjfr]

For a package you should really ask it to compile the dotted module paths (panel compile panel_full_calendar or panel compile panel_full_calendar.main, since it won't be able to correctly resolve other modules if you use a regular path. Will close for the time being.

Oh, magically it worked this time

panel compile src/panel_full_calendar/main.py --build-dir src/
Building /Users/ahuang/repos/panel-full-calendar/src/panel_full_calendar/Calendar.bundle.js containing the following components:

But now I'm wondering, what do I do with this Calendar.bundle.js when I publish to PyPI? Do I need to add it to MANIFEST.in?

I think MANIFEST.in is no longer needed with modern build tools, should be included by default by hatch I think, but try it and confirm.
