Automating promises in a service

I have some very inefficient code in a service that I would like to streamline. var dayPromise = DayResource.query({ start: dateQueryParam, end: dateQueryParam }).$promise.then(function(response) { if (response.length) { response = response[0]; MealLogResource.query({ … }, function(mealLog) { mealLogDeferred.resolve(mealLog); }); … … … } var dayBack1Promise = DayResource.query({ start: dateQueryParamBack1, end: dateQueryParamBack1 }).$promise.then(function(response) { if (response.length) { response = response[0]; MealLogResource.query({ … }, function(mealLog) { mealLogDeferredBack1.resolve(mealLog); }); } else { // Instantiating new empty day response = […]

How to use angular 1.x services to update one component from another?

So I have a parent component that has a ton of smaller components inside of it. The general idea is that I need one component to take in the data in an input and display it on another component. This is what I have which doesn’t quite work, more details on the problem afterwards: const app = angular.module(‘app’, []); app.service(‘dataService’, function() { let data = { key1: “”, key2: “”, key3: { key4: 0, key5: […]

scope variable can not be setted inside service callback

I have the following code: svcUploadMidia.load(scope.TableId, scope.TableName, function(res) { scope.Midias =; for(var i = 0; i < scope.Midias.length; i++) { scope.Midias[i].conteudoBase64 = “data:image/png;base64,” + scope.Midias[i].conteudoBase64; } }, function(err) { errorHandler(err); }); This code is inside a directive and is called by another directive. But all changes made inside the svcUploadMidia.load callback is not setted in the directive scope.Midias and the ng-repeat in the html still empty. Someone know how can I fix it? Source: AngularJS

AngularJS SET service variable in controller, and use GET it everywhere else without $watch

Here is my basic service to SET and GET the value: .service(‘companyService’, [ function () { var self = this self.options = {} function CompanyService () { self.setOptions = function (newObj) { self.options = newObj } } return CompanyService() }]) In the global controller I call my $api factory which makes an http request (with promise) to get and set Company Options. I do this only once. .controller(‘global’, [‘$scope’, ‘$http’, ‘$api’, ‘$location’, ‘$translate’, ‘$rootScope’, ‘$timeout’, […]
