How do I prefetch url's in ionic/angularjs?

Question

I am pretty new to ionic 1 and I am working on an application (with Ionic 1 and angular js) with multiple URLs where each URL brings up a list of categories, followed by a list

Answer 1

You can make multiple Asynchronous service calls in background using $q. Make a list of URL's in an array and call them at once using $q.all(listOfURL). Using promises retrieve each response.

By making this asynchronous you can save lot of time.

After getting response you can either store them in $rootScope or in localStorage/sessionStorage.
