xlwings Lite (self-hosted)

xlwings-lite is a Docker image that includes all the packages that come with the Pyodide distribution and has installation of Python packages via PyPI blocked.

To add additional packages, build your own Docker image based on the xlwings-lite base image:

1. Add your Python wheels to the packages folder. Note that the wheels need to be either pure Python wheels (e.g., mypackage-0.0.0-py3-none-any.whl) or otherwise need to be built for Pyodide.

2. Build your Docker file like so (adjust XLWINGS_LITE_VERSION and -t as desired):

   docker build --build-arg XLWINGS_LITE_VERSION=1.0.0.0-17 -t xlwings-lite-custom:1.0.0.0-17 .

3. For a quick test, you can spin up your container locally and go to http://localhost:8000, but bear in mind that Excel requires TLS certificates, so you won't be able to load this directly in Excel as an add-in (it's expected that the container hosting platform like Kubernetes, Azure Container Apps, etc. handle TLS certificates):

   docker run  --name xlwings-lite -e XLWINGS_LICENSE_KEY=YOUR_LICENSE_KEY -e XLWINGS_HOSTNAME=localhost:8000 -p 8000:8000 xlwings-lite-custom:1.0.0.0-17

NOTE: you don't necessarily need to clone this repo. Creating a packages directory together with the Dockerfile is all you need.
