Thanks for trying out anywidget. It works in JupyterLite, but it must be installed in JupyterLite distribution (and not within the running notebook). i.e., you can't %pip install anywidget without anywidget already being installed. This is related to #385.

@jtpio has compiled a version of JupyterLite where this is working. You can try it out here. The issue is that the %pip install anywidget command is out of date and needs to be %pip install anywidget==0.9.2 to sync with the correct version the build @jtpio created used.

@jtpio, I wonder if it would be possible to use a CDN-based HTMLManager in JupyterLite, to avoid this issue (and allow users to install different version of anywidget).

Thanks! I'll be setting up my own deployment following the example of @jtpio

Not sure it's possible at the moment, as it might need something like https://github.com/jupyterlab/jupyterlab/issues/8866, or more generally a way to load plugins from remote places.

Specifically, I was wondering if I could try to swap something alternative to https://github.com/jupyter-widgets/ipywidgets/tree/b78de43e12ff26e4aa16e6e4c6844a7c82a8ee1c/python/jupyterlab_widgets
