in ionic 1 i used intercepter for loading in every http request. how can i use loading for every http request at same loading. i can’t find good example. could you please help with this
Put the request logic in its own Service that also includes the Loading stuff, then use the Service instead of dealing with http directly.
I hate disagreeing with mods, but I think services should not be interacting with the view layer, so I would confine the loading to pages that are using the service, instead of trying to offload it onto the service itself.
You and your clean and maintainable code stuff… 
What if someone wants to have a http variant that always shows and hides a loading indicator when used? Where should this be put then?
