Getting app comple URL based on the environment

I’m building an email with a URL on it that change depending on the
environment I’m at. For example http://localhost:3000/demo on
development and http://www.xyz.com/demo on production.

Is there any environment variable or method that could tell me the
complete URL of my web application? I’m looking for an alternative to
environment config files.

request.domain in your controller should do it
