How to properly raise a vue + node application on a vps server?

Question

Node.js

Hello.
This is my first time setting up a server for an application. There are incomprehensible moments.

The vue application itself is currently running on port 80.

node works on port 3001

If you write something like this in the axios settings
baseURL: ' mydomain.com:3001/api/v1 '
then nothing works

Tell me how to properly configure the server for communication between vue and node?

Answer 1

1) on the server side, use the command "netstat -tnlp" to make sure that the node really hangs on port 3001
2) use postmana to test api
