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.
