Configuration#

JupyterLite-sphinx can be configured in your conf.py file by setting some global Python variables:

JupyterLite content#

You can embed custom content (notebooks and data files) in your JupyterLite build by providing the following config:

jupyterlite_contents = ["./path/to/my/notebooks/", "my_other_notebook.ipynb"]

jupyterlite_contents can be a string or a list of strings. Each string is expanded using the Python glob.glob function with its recursive option. See the glob documentation and the wildcard pattern documentation for more details.

JupyterLite dir#

By default, jupyterlite-sphinx runs the jupyter lite build command in the docs directory, you can overwrite this behavior and ask jupyterlite to build in a given directory:

# Build in the current directory
jupyterlite_dir = "/path/to/your/lite/dir"

Pre-installed packages#

In order to have Python packages pre-installed in the kernel environment, you can use jupyterlite-xeus, with the xeus-python kernel.

You would need jupyterlite-xeus installed in your docs build environment.

You can pre-install packages by adding an environment.yml file in the docs directory, with xeus-python defined as one of the dependencies. It will pre-build the environment when running the jupyter lite build.

Furthermore, this automatically installs any labextension that it founds, for example installing ipyleaflet will make ipyleaflet work without the need to manually install the jupyter-leaflet labextension.

Say you want to install NumPy, Matplotlib and ipycanvas, it can be done by creating the environment.yml file with the following content:

name: xeus-python-kernel
channels:
  - https://repo.mamba.pm/emscripten-forge
  - https://repo.mamba.pm/conda-forge
dependencies:
  - numpy
  - matplotlib
  - ipycanvas

JupyterLite config#

You can provide custom configuration to your JupyterLite deployment.

jupyterlite_config = "jupyterlite_config.json"

Disable the .ipynb docs source binding#

By default, jupyterlite-sphinx binds the .ipynb source suffix so that it renders Notebooks included in the doctree with JupyterLite. This is known to bring warnings with plugins like sphinx-gallery, or to conflict with nbsphinx.

You can disable this behavior by setting the following config:

jupyterlite_bind_ipynb_suffix = False

Suppressing jupyterlite logging#

jupyterlite can produce large amounts of output to the terminal when docs are building. By default, this output is silenced, but will still be printed if the invocation of jupyterlite build fails. To unsilence this output, set

jupyterlite_silence = False

in your Sphinx conf.py.
