Yeah, Meteor was pretty amazing when it first came out. It felt like it was from several years in the future. As I recall, it relied on mongo on the server and a minimongo that ran in the client. It made it trivially easy to create universal real-time webapps, which was a game-changer for me at the time. Reactivity has since become mainstream, but at the time it represented a bright line / step function increase in both DX and UX.
