Supplier for a module relying on data received from the server

My current component relies on "MAT_DATE_FORMATS", but I am encountering an issue where the "useValue" needs to be retrieved from the server. Is there a way to make the provider asynchronous in this case?

export const MY_FORMATS = {
    parse: {
        dateInput: 'LL',
    },
    display: {
        dateInput:'YYYY-MM-DD',
        monthYearLabel: 'YYYY',
        dateA11yLabel: 'LL',
        monthYearA11yLabel: 'YYYY',
    },
};

@Component({
    selector: 'esp-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.scss'],
    providers: [
        {provide: MAT_DATE_FORMATS, useValue: MY_FORMATS},
    ]
})
export class AppComponent implements OnInit

I am looking for a solution where the value of "dateInput" can be dynamically fetched from the server rather than being hard coded as shown here with "YYYY-MM-DD".

Answer №1

It's clear that using either useValue or useFactory in this case is not feasible since they are synchronous operations.
