I think i will use websockets, thanks for the advice. At moment i'm using callbacks only because can't do different.
Probably async/await will be available from the next version (I've read that too).
Like discourse where all the posts can be displayed in one page and also can be filtered by their category? I feel that model makes category more like a tag and allows people to see everything at once.
Is there technical issue why this cannot be achieved? Maybe it can be a theme idea?
I really like nodebb as a fast and modern forum technical wise, but also enjoy the UI philosophy behind discourse..
