How to properly raise the Swagger server to access the page with "routes"?

Question

API

Locally, I have a page with Swagger displayed at the URL: localhost:3002
In order to start the server, you need to write npm run start.
Is it possible to have access to Swagger inside another project? Poidee if I place the folder on the same server, it is possible not to write npm run start?

An example of how it should work, but only on hosting.
