NGINX setup for separate Vue Frontend and Express Backend

I am wondering about the proper nginx setup when deploying a vue frontend separately from an express backend - not separately in terms of servers or domains, but in terms of how they are served.

During development, I use npm serve in the vue directory, and to build a production build, it is generated via npm run build. The resulting dist folder should be served, and my question is how this is done when the backend is on the same server.

Let's say for the backend, express is exposing routes. Should nginx be in front of express here? The vue front end is calling those routes, but the static files need to be served. According to the docs this can be done using serve. Is this intended for production? And then again, should nginx be in front of this?

I am wondering, because the route would then be:

Browser Request -> Nginx to Vue Frontend -> Vue Frontend -> Nginx to Backend

Is this a suitable approach or am I misunderstanding this?

Yes, it is a very good idea.

You have to use a distinct set of URLs for Vue and Express, so Nginx, while looking at request URL, will be able to understand what to do: give a Vue file or proxy to Express. Nginx has a variety of options how to classify incoming requests: by different hostnames, by paths, by combination of both, etc.

For example, prepend all your Express routes with /api/ path prefix. Then configure nginx like this:

This is not production ready configuration, I'm just trying to give a hint what you should look for in nginx docs

server {
  listen 80;
  server_name mydomainname.com;

  location /api {
    proxy_pass http://localhost:8000;  # port that Express serves,
                                       # better change to UNIX domain socket
  }

  location / {
    root /vue_root/dist;
  }
}
