How to use angular2 built-in date pipe in services and directives script files [duplicate]

I need to use angular2's date pipe in services and directives script files(not only in HTML).

Does anyone have ideas?

Can't upload code cos some policy restrictions, sorry about that.

Solution 1:

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());
}

Solution 2:

In your component

import { DatePipe } from '@angular/common';

If you are using Angular 2, 4 version, try

new DatePipe().transform(myDate, 'yyyy-dd-MM');

If you are using Angular 6 and above

new DatePipe('en-US').transform(myDate, 'yyyy-dd-MM');

Hope this will help.
