@vendasta/taxonomy-service v2.0.2

Taxonomy Service

This provides a service for other components to use to retrieve taxonomy information.

Requirements

The Taxonomy Service interface:

export interface TaxonomyOption {
  name: string;  // The name of the taxonomy option
  fullName: string;  // The full name of the taxonomy option, including parent taxonomies
  id: string;  // The id that represents this taxonomy option
}

export interface TaxonomyServiceInterface {
  getTaxonomyIds(): Observable<TaxonomyOption[]>;
}

To implement the interface make a new service that implements the interface:

…
import {TaxonomyServiceInterface} from '@vendasta/taxonomy-service';

@Injectable()
export class TaxonomyService implements TaxonomyServiceInterface {
  …
  getTaxonomyIds(): Observable<string[]> {
    // Implement how the project determines taxonomy ids
  }
}

Next you will need to provide your service as that interface (generally in app.module.ts)

import { TaxonomyService } from './taxonomy.service';
import { TaxonomyServiceInterfaceToken } from '@vendasta/taxonomy-service';
…
@NgModule({
  …
  providers: [
    TaxonomyService, {provide: TaxonomyServiceInterfaceToken, useExisting: TaxonomyService}
  ],
})

• Note: To be able to inject an interface, you will have to provide the InjectionToken and not the interface itself (TaxonomyServiceInterfaceToken vs TaxonomyServiceInterface).
