# note in most cases the YELB_APPSERVER_ENDPOINT would be window.location.host <-- NOOOOO (bisogna solo compilare angular con env PROD)!!!!
# it essentially points back to the same host (NGINX) that serves the html5/angular binaries and that also acts as a proxy to the yelb-appserver
# the true meaning of the YELB_APPSERVER_ENDPOINT variable is when you want to decouple the shipping of the html5/angular binaries (e.g off of S3)
# from the yelb-appserver end-point (e.g. API Gatway) in a serverless deployment
