[MarcSkovMadsen]

With Panel==0.12.1, ipywidgets_bokeh==1.0.2, ipykernel==5.5.5 and Ipysheet==0.5.0 when I try to run the below script I get a

Loading failed for the <script> with source “https://unpkg.com/ipysheet@~0.5.0/dist/index.js”.

Serve the below with panel serve name_of_script.py

import panel as pn
import ipywidgets as ipw
import ipysheet

pn.extension("ipywidgets", sizing_mode="stretch_width")

accent_base_color = "#2F4F4F"
template = pn.template.FastListTemplate(
    site="Awesome Panel",
    title="IPySheet",
    accent_base_color=accent_base_color,
    header_background=accent_base_color,
    header_accent_base_color="white",
)
theme = "dark" if template.theme == pn.template.DarkTheme else "default"

def get_widget(theme="default", accent_base_color="blue"):
    slider = pn.widgets.FloatSlider(value=10, start=0, end=100)
    sheet = ipysheet.sheet()

    ipysheet.cell(1,1, "Input")
    cell3 = ipysheet.cell(1,2, 42.)
    ipysheet.cell(2,1, "Output")
    cell_sum = ipysheet.cell(2,2, 52., read_only=True, background_color=accent_base_color)

    @pn.depends(slider, cell3, watch=True)
    def calculate(a,b):
        cell_sum.value = a+b
        print("update", cell_sum.value)

    return pn.Column(slider, sheet)

widget = get_widget(theme=theme, accent_base_color=accent_base_color)
component = pn.panel(widget, height=500, sizing_mode="stretch_both")
template.main.append(component)
template.servable()

Same here for voila==0.2.10. Works fine in jupyterlab and notebook though.

Definitely an issue since this is where the @jupyter-widgets/html-manager tries to fetch the package from CDN:

Any update on this? It would be awesome to make ipysheet compatible with Google Colab https://github.com/googlecolab/colabtools/issues/2594

Running into the same problem in VS Code, looks like the files pushed into CDN for 0.5.0 are JS modules, where as the preivous version used requirejs and included everything in the artifacts published to the CDN.

Is this an oversight os is this deliberate? I.e. should the consumers of this file on the CDN change how these files are now consumed/loaded? Not sure that will work though as there are quite a lot of missing packages (handson tables and the like)
