Deployment of Templated Apps to Binder using jupypter-panel-proxy not working.

[MarcSkovMadsen]

Panel 0.11

My Pain

I would like to demonstrate to colleagues and the Panel community how easy it is to share Panel apps on binder. It's really just adding jupyter-panel-proxy as described in the Panel docs and your notebooks in the root directory.

But no. The world is not so easy and the FastGridTemplate does not work

Reproducing Steps

Additional Context

I would also in the near future have access to a JupyterHub and would like to run my panel apps there. And it would be the same problem on JupyterHub.

So there is a large community of users on Universities, Govt. institutions and in Enterprises that do not have easy access to share their Panel apps via JupyterHub.

Additional Context

When running locally the app looks like

Additional Context - reverse proxy

I believe the problem is more general tjen jupyter deployment. I believe panel have problems whenever it’s deployed besind a reverse proxy to a non-root path.

For example at work I deploy to kubernetes and i have to serve my panel apps at /. If i serve them at /panel-apps my bundled static files cannot be found. Because panel looks for them at /static not / panel-apps/static

Thus a whole lot of kubernetes users/ reverse proxy users will not be able to deploy their panel apps.

Yes, I think the paths are getting mangled here. We should fix this and then release 0.11.1.
