Pass custom config options to labextensions frontend

[rsinha25]

Hi,

I used to do this in the earlier labextension using the steps mentioned in the tutorial:

# Jupyter Lab Extension config data.
def _jupyter_labextension_config():
  """Get a dictionary of configuration data to provide to the JupyterLab frontend.

  This is called at each launch of the `/lab` page, and makes data available 
  through the `getConfigOption` [function](http://jupyterlab.github.io/services/globals.html#getconfigoption).

  Example in ES6 JavaScript:
  import { utils } from '@jupyterlab/services';
  let myVar = utils.getConfigOption('my_fancy_module_variable');
  """
  return dict(my_fancy_module_variable=1)

However, this doesn't work in the latest version as there is no python package anymore. How can I now pass custom config options and use them in labextension frontend?

We decided that front end and back end extensions should remain separate. An extension that wants to affect the backend must also provide a server extension. They can affect the front end using page_config, an example of which is here.
