JupyterLite is a great project!

Addressing some other comments: the main limitation you'll find is probably the filesystem. WASM File System APIs are not extremely well evolved and (i think?) they're still in-memory FSs.

JupyterLite has a binding between the browser local storage and the WASM File System, so you can create a file from Python and it will be saved in the browser local storage for next time you come

Files seem to persist even after quitting chrome, refreshing or closing the tab. I'm not an expert, but assume it's cookie storage.

I think JupyterLite is using localStorage by default. But there are File System APIs for WASM and some external projects[0], I don't think they're yet integrated.

This has been a problem when using Konqueror.

Thanks, yes I see it now. It stores the notebook, which is a json, as a value in the localStorage object, with the filename as a key. Interesting, yes, not quite easy to configure (though I haven't read through the documentation or code to find this).
