Automerge is a great project, but it feels still way to academic in it's setup. If you need a superior DX and CRDT-based full-stack database, I'd recommend you to look at Triplit.dev and their docs.
(while development has decreased somewhat, the product is in a fully-featured phase and should work well for anything from small to medium, probably also very large projects depending on your configuration). Give it a try, you will like it.
