Thanks for sharing. We haven't cracked the code on doing this locally, but we are working on similar features and functionality in MotherDuck, like the prompt () and embedding () functions. More to come; we're definitely thinking about it!
Just wondering about reactivity, imports, exports, plain file storage? I don't expect it to be there on a first release, but that's where my mind goes if I see a reference to the notebook form factor.
MotherDuck lets you run a fleet of DuckDB instances as a managed cloud service.
