This project provides a way for JupyterLab and other frontends to switch to Jupyter Server for their Python Web application backend.
Install from PyPI:
pip install notebook_shim
This will automatically enable the extension in Jupyter Server.
This project also includes an API for shimming traits that moved from NotebookApp in to ServerApp in Jupyter Server. This can be used by applications that subclassed NotebookApp to leverage the Python server backend of Jupyter Notebooks. Such extensions should now switch to ExtensionApp API in Jupyter Server and add NotebookConfigShimMixin in their inheritance list to properly handle moved traits.
For example, an application class that previously looked like:
from notebook.notebookapp import NotebookApp
class MyApplication(NotebookApp):should switch to look something like:
from jupyter_server.extension.application import ExtensionApp
from notebook_shim.shim import NotebookConfigShimMixin
class MyApplication(NotebookConfigShimMixin, ExtensionApp):
