@luxury-presence/nestjs-plunk NPM

Description

Plunk module for Nest based on the plunk api.

Installation

$ npm i --save @luxury-presence/nestjs-plunk @nestjs/axios rxjs

Usage

Import PlunkModule:

@Module({
  imports: [PlunkModule.register({
    apiKey: 'PLUNK_API_KEY',
  })],
  providers: [...],
})
export class SearchModule {}

Inject PlunkService:

@Injectable()
export class SearchService {
  constructor(private readonly plunkService: PlunkService) {}

  async findByAddress(address: string): Promise<Address> {
      return this.plunkService.findAddresses(address);
  }

  async findByParcelId(parcelId: string): Promise<Valuation> {
      return this.plunkService.getHomeValuationByParcelId(parcelId);
  }
}

Async options

Quite often you might want to asynchronously pass your module options instead of passing them beforehand. In such case, use registerAsync() method, that provides a couple of various ways to deal with async data.

1. Use factory

PlunkModule.registerAsync({
  useFactory: () => ({
    apiKey: 'PLUNK_API_KEY',
  })
});

Obviously, our factory behaves like every other one (might be async and is able to inject dependencies through inject).

PlunkModule.registerAsync({
  imports: [ConfigModule],
  useFactory: async (configService: ConfigService) => ({
    apiKey: configService.get('PLUNK_API_KEY'),
  }),
  inject: [ConfigService],
}),

2. Use class

PlunkModule.registerAsync({
  useClass: PlunkConfigService
});

Above construction will instantiate PlunkConfigService inside PlunkModule and will leverage it to create options object.

class PlunkConfigService implements PlunkModuleOptionsFactory {
  createPlunkModuleOptions(): PlunkModuleOptions {
    return {
       apiKey: 'PLUNK_API_KEY',
    };
  }
}

3. Use existing

PlunkModule.registerAsync({
  imports: [ConfigModule],
  useExisting: ConfigService,
}),

It works the same as useClass with one critical difference - PlunkModule will lookup imported modules to reuse already created ConfigService, instead of instantiating it on its own.
