I just want to know the correct way to serve an angular universal app with an existing nodejs/express server that talks to a Mongodb database and serves data with an "/api/*" route for example.
So is it to have the universal app have its own node/express server as explained here https://angular.io/guide/universal and just merge that with the existing node/express server with route configuration as done here Serve angular universal app with NodeJS/ExpressJS back-end and allow both the custom node/express server and the universal apps express server have different ports (because i assume that is how they will be able to co-exist in production)
Or do we use the custom node/express server as the server for the universal app with proper configuration.
