Is there a way in Angular to determine when all service calls have completed so that I can stop a loading bar in the controller?
Is there a way in Angular to determine when all service calls have completed so that I can stop a loading bar in the controller?
To improve your Angular application's performance, consider implementing an interceptor. An interceptor is a factory that intercepts all requests and responses made by your application.
app.factory( 'Inteceptor', function($rootScope) {
int count = 0;
return {
request : function() {count++},
requestError : function() {},
reponse : function() {
count--;
if( count == 0 ) {
$rootScope.$broadcast( 'Event' )
}
},
responseError : function() {}
}});
This interceptor keeps track of the total number of requests sent. By starting at zero, incrementing on request, and decrementing on response, you can easily determine when all requests have been completed by broadcasting an event.
To add this interceptor, include it in the config method like this:
$httpProvider.interceptors.push('CustomHttpInterceptor');
