destroy or something similar may come to the CLI, but it is not a primary focus at this time. So you will need to do this manually. Delete the component directory (assuming you didn’t use –flat) and then remove it from the NgModule in which it is declared. If you are unsure of what to … Read more
Below changes works for me on Angular 2 final version: export class AppSettings { public static API_ENDPOINT=’http://127.0.0.1:6666/api/’; } And then in the service: import {Http} from ‘angular2/http’; import {Message} from ‘../models/message’; import {Injectable} from ‘angular2/core’; import {Observable} from ‘rxjs/Observable’; import {AppSettings} from ‘../appSettings’; import ‘rxjs/add/operator/map’; @Injectable() export class MessageService { constructor(private http: Http) { } … Read more
In Angular 5, the query params are accessed by subscribing to this.route.queryParams (note that later Angular versions recommend queryParamMap, see also other answers). Example: /app?param1=hallo¶m2=123 param1: string; param2: string; constructor(private route: ActivatedRoute) { console.log(‘Called Constructor’); this.route.queryParams.subscribe(params => { this.param1 = params[‘param1’]; this.param2 = params[‘param2’]; }); } whereas, the path variables are accessed by this.route.snapshot.params Example: … Read more
In most cases you will want to use {static: false}. Setting it like this will ensure query matches that are dependent on binding resolution (like structural directives *ngIf, etc…) will be found.

If you want to have a current value, use BehaviorSubject which is designed for exactly that purpose. BehaviorSubject keeps the last emitted value and emits it immediately to new … Read more

I think that is a bad solution. If you want to pass a Function into component with @Input(), @Output() decorator is what you are looking for. export class SuggestionMenuComponent { @Output() onSuggest: EventEmitter<any> = new EventEmitter(); suggestionWasClicked(clickedEntry: SomeModel): void { this.onSuggest.emit([clickedEntry, this.query]); } } <suggestion-menu (onSuggest)=”insertSuggestion($event[0],$event[1])”> </suggestion-menu>
In your component’s template you can use multiple arguments by separating them with colons: {{ myData | myPipe: ‘arg1′:’arg2’:’arg3’… }} From your code it will look like this: new MyPipe().transform(myData, arg1, arg2, arg3) And in your transform function inside your pipe you can use the arguments like this: export class MyPipe implements PipeTransform { // … Read more
After Angular 2.0 final release, the structure of the Angular2 CLI project has been changed — you don’t need any vendor files, no system.js — only webpack. So you do: npm install font-awesome –save In the angular-cli.json file locate the styles[] array and add font-awesome references directory here, like below: “apps”: [ { “root”: “src”, … Read more
