Ionic v4 using the Angular CLI v6 allows to use different environments configurations, cool 
But, anyone knows how to manage different configuration inside the index.html?
For example, in my index.html I’ve got a CSP rule wich restrict connect-src to my prod server. Of course when I debug locally I want to connect to the proxy in order to connect to my staging. So far I always ran gulp scripts to switch between config and payed attention to never commit the changes, but maybe with the introduction of environments there is another solution now?
