Jupyter Server Roadmap

[Zsailer]

In today's call, we put together a technical roadmap for the Jupyter Server. Here's a place to discuss the plan.

---

• Release nbclassic
  • a notebook ExtensionApp (from jupyter_server).
  • pulls Notebook JS and templates from notebook.
  • execute from command line with jupyter nbclassic
  • migrates configuration to jupyter_server_config.
  • shim notebook vs. server traits.
• Setup Jupyter Server's Testing Framework
  • Port old tests to pytest.
  • Move to Github actions
    back to old way.
• Update Jupyter Server JEP to reflect new nbclassic.
• Transition other frontends:
  • JupyterLab to Jupyter Server, dropping notebook as a dependency.
  • voila to Jupyter Server
  • Uses nbclassic to run multiple frontends side-by-side.
• Notebook 7.x: transition jupyter/notebook to Jupyter Server
  • drop the old notebook server
  • NotebookApp becomes
  • shim the notebook server API to jupyter_server
  • raise DeprecationWarnings in shimmed APIs.
  • release notebook 7.x
• Notebook 8.x: drop shims.

Just moved Zsailer/notebook_shim to Zsailer/nbclassic.

NBClassic is a thin package that provides the classic Jupyter Notebook frontend on top of Jupyter Server. You can install NBClassic side-by-side with notebook. NBClassic uses the Javascript and templates from notebook, but runs on the Jupyter Server's tornado server (not the notebook's native tornado server).

You can install nbclassic from PyPI today.

pip install jupyter_server nbclassic notebook

You can try the nbclassic frontend by running jupyter server or jupyter nbclassic and going to localhost:<port>/tree?token=...

@Zsailer I've gone ahead and pinned this issue for visibility. Thanks for putting it together!

[Zsailer]

Thanks, @willingc!

[echarles]

didn't know about the pinned feature, learning every day here...

Good to have more visibility here but further actions could be needed in downstream projects that are using notebook or are/will be using server. This is especially true for the kernel_mgmt - nbclassic should have 0 impact I believe.

See jupyter-server/jupyter_server#190

Closing this issue, as this roadmap is very out-of-date. We'll work on developing a new roadmap in the new year, once a Jupyter Server Team is established.

Where will the new roadmap be communicated?
