How to know that angular completed all processing and rendering

I need to stop progress bar. If I have several http request, how can i know when all threads completed, and all responses are rendered. I tried to use $httpProvider.interceptors on response, but i can not know whether this is the last http response or not. And also you can not know when this last response will be rendered.

You can track the pending request by http.pendingRequests in your interceptor like

angular.module('myApp').factory('myHttpResponseInterceptor', function($q, $location, $injector, $rootScope){
    var _http = null;

    return {
        request: function(config){
            $rootScope.$broadcast("loader_show");
            return config;
        },
        response: function(response){
            _http = _http || $injector.get('$http');
            if(_http.pendingRequests.length < 1){
                $rootScope.$broadcast("loader_hide");
            }
            return response;
        },
        responseError: function (response) {
            _http = _http || $injector.get('$http');
            if(_http.pendingRequests.length < 1){
                $rootScope.$broadcast("loader_hide");
            }
            console.log("response rejected in interceptor");
            return $q.reject(response);
        }
    };
});

I have used this in my project and it works just fine.

Hope it helps you too.

You can use a module like angular-busy or ngProgress to do the same.
