Something something Dropbox
A part of HN history, if you will, making light fun of the "it's just a wrapper" idea that transitions into a multi billion dollar company, because only naively is execution and the integration of different ideas a trivial task. The people at NextJS are obviously(?) doing something that's not just Express and you can look at the version history if you are interested in identifying those things.
Of course, you might not think of them as important. But that's a very different take.
