Angular js - detect when all $http() have finished

Question

Ok i have tons of $http() calls all around the app code,

i\'m wondering is there any way / best practice to detect when all $http() around

Answer 1

It is possible if you execute all requests by $q.all

$scope.request1 = $http.get('request1URL', {cache: false});
$scope.request2 = $http.get('request2URL', {'cache': false});
$scope.loading = true;

$q.all([$scope.request1, $scope.request2]).then(function(values) {
     $scope.loading = false;
     // Do whatever you want
     // values[0], values[1]
});

Using ng-if, you can show and hide loading gif.

In case, if you use different $http call, then have a count or array in the $rootScope and update them whenever $http complete. Based on the count or array.length enable the loading gif.
