Starred.

If I ever try Firebase it will be nice to have this.

Code looks nice! Except like sibling commenter I'm not sure what good typing/programming would look like if doing an ORM in TS.

It's my first time hearing about Firestore by the way. My understanding is Firebase has a real time store, but Firestore is a different tool, similar to MongoDB?
