问题 I have 2 components (Menu and Header) and one Service. What I want to do is that when they select an item from the menu, the menu sends the text to the service and the service sends it to the header and changes it. I already managed to send it to the service, but I do not know why in the header with the Observable it does not update. Service: import { Injectable } from '@angular/core'; import { Observable } from 'rxjs'; import 'rxjs/add/observable/from'; import { of } from 'rxjs'; @Injectable

问题 I am using Jhipster Spring boot + angular 6. But i'm having trouble because of the hash(#) in URL. It is affecting SEO. I tried setting useHash: false in app-routing-module.ts . But then the API is not working when I run the project via npm start . I think somewhere in Java files I have to change a configuration to remove # from the URL. Here is my WebConfigurer code, @Configuration public class WebConfigurer implements ServletContextInitializer, WebServerFactoryCustomizer<WebServerFactory> {

Angular 6 Follow up: [attr.disabled] in option value disables all entries

跟風遠走 提交于 2019-12-06 09:52:12
Topic: Angular 6, Reactive Form, DropDown Menu, Disable One Option: all instead of just the one intended value are disabled, even though the inspector says disabled=false. People were very kind to help me with my problem earlier: " Angular 6 Reactive Form - Select options: disable previously selected options " but they seemed to disappear after I hit a roadblock, hence my new question: Why are ALL option values disabled instead of just the one that is supposed to match the statement? [attr.disabled]="uplink2x === dropdown1Val" (even if I hardcode nic0 instead of dropdown1Val all options are

NgRX Effect for downloading media file and dispatching progress; how to deal with the stream and throttling

Angular Module vs. Library

主宰稳场 提交于 2019-12-06 07:11:11
So great, the Angular has released version 6 and the CLI provides an option to generate libraries - something that they call a "highly anticipated feature". Now, coming from a business perspective, I am wondering: why you would actually need this, why inside of an existing project and not a separate which you can install as usual via npm... and if you want this inside your project, why not use a module for that. So I get it, publish something on npmjs and hope the whole world and future connected things need exactly that. Library, great. Inside a big system in a even bigger company, we could

问题 In previous version, spec.ts can be disabled with .angular-cli.json as below. Is there any way to do it with angular.json in version 6.0.0?
