Ability to Access Jupyter Server

There are some widgets that require Jupyter Server Extensions. The client then needs to know the base URL where the Jupyter server can be found so that it can reach any assets which may have been added to the server via an extension. In normal notebooks, the base URL of the server can be discovered in a couple different ways which are described by the following function:

const jupyterServerBaseUrl = (() => {
  const jupyterConfig = document.getElementById("jupyter-config-data");
  if (jupyterConfig) {
    return JSON.parse(jupyterConfig.text)["baseUrl"];
  }
  return document.getElementsByTagName("body")[0].getAttribute("data-base-url");
})();

Is there a similar way to discover the Jupyter server’s base URL in VSCode?

I managed to get things working. The way I’m doing it feels quite hacky, but it does the trick. Basically I use notebook.notebookapp.list_running_server to see if there are any running notebook servers. If there are, I ping the route where I expect my resources to be. If the ping fails, then I know I need to stand up my own static file server and use that instead.

I’m sorry, but right now there isn’t one.

Are there any plans to implement this?

Is this for an organization setup or class room or the like?

This is for an organization setup. I’m a software developer working at AWS CQC to support a team of researchers. We don’t have an internal JupyterHub yet so researchers would need to repeatedly and manually stand up a local Jupyter Server to use the widget in question.
