how to use datepipe in ts file
// Since CommonModule does not export it as a provider you'll have to do it yourself. This is not very complicated. //1) Import DatePipe: import { DatePipe } from '@angular/common'; // 2) Include DatePipe in your module's providers: NgModule({ providers: [DatePipe] }) export class AppModule { } // or component's providers: @Component({ selector: 'home', styleUrls: ['./home.component.css'], templateUrl: './home.component.html', providers: [DatePipe] }) export class HomeComponent { ... // 3) Inject it into your component's constructor like any other service: constructor(private datePipe: DatePipe) { } // 4) Use it: ngOnInit() { this.time = this.datePipe.transform(new Date()); }
