Deploy JupyterLite on a standalone server or locally#
Deploying a JupyterLite site requires:
a copy of the JupyterLite site assets
often provided by the
pip-installable python package
an option set of configurations for the site and different apps
different options offer trade-offs between reproducibility, build speed, deployment size, and end-user performance, privacy, and security
Get an Empty JupyterLite Site#
The minimum deployable site archive contains enough to run all of the default applications, but no content.
Use of the CLI is optional, but recommended. It offers substantially better integration with other Jupyter tools.
python -m pip install --pre jupyterlite
jupyterlite will soon be available on conda forge
To build an empty site (just the JupyterLite static assets):
jupyter lite init
By default the JupyterLite website will be placed in the
_output folder. You can
specific a different with
--output-dir parameter. For instance:
jupyter lite build --output-dir dist
Now that the static assets have been built, you can use a plain HTTP server to serve them and access JupyterLite from a web browser.
Suitable for local development, many languages provide easy-to-use servers that can serve your JupyterLite locally while you get it working the way you want.
Serving some of the kernels requires that your web server supports
application/wasm files with the correct headers
An HTTPS-capable server is recommended for all but the simplest
jupyter lite serve#
jupyter lite serve command offers either a web server powered by Python’s built-in
tornado, which is likely to be available if any other Jupyter tools
In the same directory, run the following command to start the server:
jupyter lite serve
More options are also available such as changing the port and log level.
Check out the help with
jupyter lite serve --help to learn more.
If you’re already running a Jupyter Server-powered app, such as JupyterLab, your files
will be served correctly on e.g.
http module in the Python standard library is a suitably-effective server for
python -m http.server -b 127.0.0.1
If you are using a recently-released Python 3.7+, this will correctly serve
application/wasm files for WebAssembly kernels.
Most nodejs-based servers will be able to host JupyterLite without any problems. Note,
http-server does not support the
application/wasm MIME type.
Using a release archive#
As an alternative to using the
jupyterlite CLI, you can also download a release
archive from the GitHub Releases page.
Download it an extract it, then use one of the approaches mentioned above to start the server.
Nightly and work-in-progress archives are also available from GitHub actions.
