I’ve figured it out.
In the start file that launches the application, all modules for your project must be imported.
And also, if this suddenly does not help, you can do it manually using the button:
from pages import home, page1, page2
...
def reload_click(event):
for module_name in list(sys.modules.keys()):
if module_name.startswith('pages.'):
print(module_name)
importlib.reload(sys.modules[module_name])
# Reload the current page
current_page = pn.state.location.query_params.get('page')
pn.state.location.param.update(search=f"?page={current_page}")
pn.state.location.reload = False
pn.state.location.reload = True
reload_button = pn.widgets.Button(name='Reload', on_click=reload_click)
And modules, which are in folder page, reloading fine
