I'm having issues deploying my Panel app to be served up as HTML.
Following instructions at https://panel.holoviz.org/user_guide/Running_in_Webassembly.html, with script.py as
import panel as pn
from mymodule import MyObj
pn.extension('terminal', 'tabulator', sizing_mode="stretch_width")
gspec = pn.GridSpec(sizing_mode='stretch_width', max_height=100, ncols=3)
PI = MyObj()
gspec[0, 0:1] = PI.tabs
gspec[0, 2] = PI.view
pn.Column(
"Text Text Text"
, gspec
).servable()
and mymodule/__init__.py:
__version__ = '0.1.0'
from .my_obj import MyObj
and mymodule/my_obj.py:
from .param_classes import ClassA
from .param_classes import ClassB
# etc
from .compute_obj import ComputeObj
class MyObj(object):
# all the details of the panel build, calling in turn
# param classes detailed in another file, and also calling another module
# to handle all the computation behind the panel
panel serve script.py --autoreload works perfectly, but
$ panel convert script.py --to pyodide-worker --out pyodide
$ python3 -m http.server
does not work. I get a big display at http://localhost:8000/pyodide/script.html: ModuleNotFoundError: no module named 'mymodule', and an infinite loop spinning graphic, and in the Developer Tools Console output:
pyodide.asm.js:10 Uncaught (in promise) PythonError: Traceback (most recent call last):

I should add that I'm using poetry to manage packages and build the venv, and I'm operating all the above from within the activated .venv (via poetry shell)
I've tried all the tips and tricks around append the local path to sys.path. Looking at the .js file that the convert utility generates, I gather it would work if all the code were in one file, but forcing bad coding practice doesn't sound right.
I imagine there could be some kind of C++ build-style --include argument to panel convert, but there are no man pages, and the closest I can get with online documentation is --requirements ./mymodule, but no joy.
Could anybody please advise?
