If I change the survey
argument to https
then first issue goes away.
import panel as pn
from ipyaladin import Aladin
pn.extension("ipywidgets")
aladin = Aladin(
survey="https://alasky.cds.unistra.fr/DECaPS/DR1/color/",
show_coo_grid=True,
target="galactic center",
coo_frame="galactic",
fov=40,
height=600,
)
pn.panel(aladin).servable()
But CORS issue remains.
That is what ChatGPT says is required to fix the issue:
The error message you're seeing is related to Cross-Origin Resource Sharing (CORS) policy. This is a security measure implemented by web browsers to prevent requests to different domains (cross-origin requests) unless the server specifies that it allows such requests.
In this case, the server at 'https://alasky.cds.unistra.fr/' is not sending the 'Access-Control-Allow-Origin' header in its response, which is why the browser is blocking the request.
To fix this issue, the server administrator for 'https://alasky.cds.unistra.fr/' needs to update the server's configuration to include the 'Access-Control-Allow-Origin' header in its responses. This header should be set to the origin of the request ('https://SOMe-DOMAIN/' in this case) or to '*' to allow requests from any origin.
If you don't have control over the server at 'https://alasky.cds.unistra.fr/', you might need to contact the server administrator or the service provider and ask them to make this change.
Using alasky.u-strasbg.fr
seems to work 👍
import panel as pn
from ipyaladin import Aladin
pn.extension("ipywidgets")
aladin = Aladin(
target="159.2135528 -58.6241989",
survey="https://alasky.u-strasbg.fr/Planets/Mars_Viking_MDIM21",

pn.panel(aladin, sizing_mode="stretch_width").servable()

Just a comment. For data app usage it would be really nice to be able to set the heigth
and width
of Aladin
to "100%"
instead an integer. That makes it much easier to make modern apps the responsively adjusts to the window size of the app.
Hi
I wanted to explore ipyaladin in a Panel data app starting from this example https://github.com/cds-astro/ipyaladin/blob/master/examples/01_Getting_Started.ipynb.
Normally I can use AnyWidget components with Panel if I've installed the prerequisites:
Then create a file called app.py.
and serve it by running the below in a terminal:
Finally open it. On a laptop it would be at at http://localhost:5006. But I'm working on a Jupyterhub so its served behind a reverse proxy at
https://SOME-DOMAIN/SOME-PATH/vscode/proxy/5006/
I'm not an expert here but I think that two things could be fixed here in ipyaladin or in aladin-lite?
https
and nothttp
protocol.I think these issues are not specifically related to Panel. Other users working in notebooks on JupyterHub/ Binder or trying to deploy data apps based on ipyaladin using for example Jupyter Voila server, Shiny Py or Solara would experience the same issues.
