#Gulp
##Environments
gulp --env=[env name]
##Server on demand
Gulp runs a local server that executes tasks when a page is requested, not when the files change. It will keep track of the file changes; but instead of running the tasks directly it will run them all at once when a request arrives, before it hits the real development server.
gulp server
You should use 8080 port in order to send http request to 'on demand' server.
