Hey!
I’ve written an article with one of my friends about ProseMirror’s collab feature, specifically it’s about using a sync database ( PouchDB, but it works with firebase ) as a communication layer between client and server.
This approach makes development way faster, and if anyone wants to make a collaborative editor quickly this codebase is a good starting point.
I’d love to hear your feedback about it, and I hope it helps a few people
