JupyterLab Server sits between JupyterLab and Jupyter Server, and provides a set of REST API handlers and utilities that are used by JupyterLab. It is a separate project in order to accommodate creating JupyterLab-like applications from a more limited scope.

pip install jupyterlab_server

To include optional openapi dependencies, use:

pip install jupyterlab_server[openapi]

To include optional pytest_plugin dependencies, use:

pip install jupyterlab_server[test]

See the full documentation for API docs and REST endpoint descriptions.

Subclass the LabServerApp and provide additional traits and handlers as appropriate for your application.

Please see CONTRIBUTING.md for details.
