Skipping API call

[dg-data]

One server API call is made during initialisation to obtain the storage configuration.

If someone wants to use it in other container-based environment than Binderhub, it will not work without the offlinenotebook/config endpoint. A really offline approach would be using the config file only and omitting the server call in this case.

Hi! Would you mind explaining your use case a bit more? If you're running your container locally this extension doesn't offer you much since you can just save/download your notebook in the usual way. It does make an API call, but that doesn't require JupyterHub/BinderHub, it's a jupyter-server extension so should always be present when you first start up JupyterLab.

I try to use your extension in a preconfigured container where I can't setup anything server side. I tried the extension on MyBinder where works, basically reads the Binder specific enviroment variables on startup. In my case I need the save/restore functionality in Jupyterlab (like your version 0.0.2 in Notebook), without any call to jupyter-server for the four Binder variable, because in my environment the API endpoint is unreachable.
Thanks your consideration!
