angular-services

I started angular two days ago, i m trying to create a service that will do a get request over my spring boot rest end point and I wish to display the result in my angular app Here is what i have tried till now My Service: import { Injectable } from '@angular/core'; import { HttpClient } from '@angular/common/http'; import { ITweet } from './itweet'; import { Observable } from 'rxjs'; @Injectable({ providedIn: 'root' }) export class ReactiveTwitterService { constructor(private http_client: HttpClient, private tweetTag: string) { } spring_webflux_service_url = 'http://localhost:8081/search';

In Angular, I have a service that has few things injected through the constructor(...) . However that service is also at some place created by calling the constructor. Therefore, adding another service it depends on to the parameters would change the API. I'd like to avoid that. Is there a way to inject a service into another service without adding it to the constructor parameters? E.g. field injection? import {Inject, Injectable} from "@angular/core"; import { Http, Request, ConnectionBackend, RequestOptions, RequestOptionsArgs, Response, Headers, RequestMethod } from "@angular/http"; import

Hi I am new to angular 2+, I am trying to share data between two components but the second component is not retrieving the data from the service, it gets an empty object. Service - using rxjs BehaviorSubject to keep the object import { BehaviorSubject } from 'rxjs/BehaviorSubject'; import { Observable } from 'rxjs/Observable'; @Injectable() export class PostsService { response: any = {}; private messageResponse = new BehaviorSubject(this.response); currentResponse = this.messageResponse.asObservable(); constructor(private http: Http) { } // Get all posts from the API getAllPosts() { return

If I follow this particular practice of making factories: myApp.factory('myService', function () { var somevalue = 2; var myServiceApi = { theValue: somevalue, updatevalue: updateValue } return myServiceApi; function updateValue(newValue) { somevalue = newValue; } }); Each and every time the service is injected the value of somevalue is always initialized as 2, even though I have updated it earlier with the UpdateValue method. if I however use a getter method on the value it is update in all instances of the service. http://jsfiddle.net/IngoVals/hd1r1bmp/ What is going on in the background

I created a Modal service and when I injected the service into the controller, I am receiving an error that says "$Injector: unpr Unknown Provider". Here is my code below. Let me know if I am missing something. This is the service I have so far. 'use strict'; angular.module('myApp.services', []) .factory('modalService', ['$scope', function($scope) { return { openMenuModal: function(templateLink, windowAnimation) { var modalInstance = $modal.open({ templateUrl: templateLink, backdrop: 'static', windowClass: windowAnimation, controller: function($scope, $modalInstance) { $scope.close = function(

I am trying to use an app-wide service (UserService) that stores authenticated user details. I have set up some routes but found that UserService is instantiated per route. I want them to share the same UserService. I have created a CoreModule containing TestService as provider and imported it into AppModule. core.module.ts: import { NgModule } from '@angular/core'; import { CommonModule } from '@angular/common'; import { TestService } from '../test.service'; @NgModule({ imports: [ CommonModule ], declarations: [], providers: [ TestService ] }) export class CoreModule { } test.service.ts:
