Thank you Adrian for your very kind response.
express.js is the server framework for node.js
So...two questions come in mind:
am I obliged to use express.js as glue between node and vue, if I already
use nginx as web server?
And if I'm obliged to use another web server apart from nginx to glue
node and vue, would it be possible to use a golang web-server,
which could be a further complication but would have its own positive
sides?
