Hey, I wonder how could I add loading to my angular app.
In my page ‘Parties’ i fetch all ‘parties’ from the db. I am using helpers to find parties.
How could I know when the parties are fetched and hide to preloader? (I add preloader everytime i am frying to fetch something)
There is any promise or something else?
And when i change the parties it’s automatically saves in db. How could I know when it finished? And if there is any network error?
It’s very important. I didn’t saw it in the tutorials…
