“Real-time” in JS tends to refer to approaches like websockets.

So it's not really realtime... No ?

I noticed an instant downvote. It's not the first time i see this behavior on rxdb comments.

The definition of realtime is vague so saying that something is "not really realtime" just because it is not "realtime computing" is wrong.

In fairness it was a bit pretentious of whoever decided to call it real-time which was a word with a specific meaning and a very hard earned reputation. 'Live' might have been better.

"You see the updates in real time without having to refresh the page" seems like a perfectly reasonable statement.

I submit that being pedantic about such things is frequently its own form of pretension.

Depends on your definition of realtime. Realtime with RxDB is not like "Real-time Computing" but like realtime synchronisation how it is described by firebase https://firebase.google.com/docs/database
