From what I can gather the issue is that the code is running in the
context of the browser and net.Socket is not supported there. It seems
that the fix is to run the database code in node.js and pass the data
from there to vue.js. Honestly, this whole reactive code thing is still
something I'm wrapping my head around. I did find some tutorials
searching on 'node.js vue.js Sequelize postgresql'. Most seemed to use
express.js as the glue between node and vue.
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?
