How to correctly form the Node.js RestApi structure?

Question

Node.js

There are two applications on the same server running on different
api ports - on 3000
front - on 8080
How to implement the logic of working with files correctly? That is, if there is a function, for example, upload, then the picture is saved in the api in the public folder, how to get it on the front?

Answer 1

You can not fool around and file proxying through nginx
You will get something like
location /api/ -> proxy_pass 127.0.0.1:3000
location / -> proxy_pass 127.0.0.1:8080
and then through document_root allow you to look where you need to
