Serve directory-style apps with pn.serve?

Panel
1

I’m probably missing something here, but if I have a directory style app, how can I start it with pn.serve?

My basic structure is

myapp
   |
   +---__init__.py
   |
   +---main.py
   |
   +visualizations
   +templates

etc. etc. (like is shown in Running a Bokeh server — Bokeh 2.4.3 Documentation)

I would normally launch with panel serve myapp and works great, but I can only get it to launch when I try pn.serve(‘myapp/main.py’) and then I see the following during launch:

It looks like you might be running the main.py of a directory app directly.
If this is the case, to enable the features of directory style apps, you must
call "bokeh serve" on the directory instead. For example:

    bokeh serve my_app_dir/

If this is not the case, renaming main.py will suppress this warning.

  return _build_application(path, argv)

Just trying to make it easier for other users to start the app if they need to, without entering a laundry list of static-directories :sweat:

Can you do panel serve myapp/main.py instead?

Yes, that works fine! I see the same warning that I should be calling bokeh serve on the directory (myapp) and not mainapp/main.py but this is how I’ve been launching it historically
