Ionic serve context path

I am trying to use power of ionic as a progressive app, unfortunately I do not see any deployment option than firebase.

I would like to use my server and deploy ionic app as a web application with a URL context

unfortunlately when I do ionic serve it starts at localhost:8100 and I need to append a /<> as a context.

Is there a way in IONIC to do that?

Thank you in advance for your help and advise.
