Deployment and productive scenerio for XSA MTA

I have scenerio where I have created a MTA application with Node.js module and HDI only.

Now I want to expose Node URL for customers use, but every time I have to run server.js in XSA Webide in order to index.xsjs to run on localhost.

I have below questions in above scenerio

1) How this will work in non-Dev environment where I am not able to run the server.js manualy (like in QA or PRoduction).

2) Deployment/migration steps for this solution for subsequent environment in the landscape.
