GeoDB Angular Client

This library provides Angular client bindings to the GeoDB service.

Setup

1. cd into your Angular project root.

2. npm install wft-geodb-angular-client@latest --save

If using the FREE instance, update your SampleAppModule.ts as follows:

@NgModule({
  declarations: [
    ...
  ],
  imports: [
    ...
    GeoDbFreeModule.forRoot({
      apiKey: null,
      serviceUri: http://geodb-free-service.wirefreethought.com
    })
  ],
  bootstrap: [AppComponent]
})
export class SampleAppModule { }

Otherwise, if using the PRO instance:

1. Create an account on RapidAPI. As part of account creation, Rapid asks for credit-card info. As long as you stay within the free usage limits of the Basic plan, your credit card will not be charged.
2. Select a GeoDB plan.
3. Update your SampleAppModule.ts as follows:

   @NgModule({
     declarations: [
       ...
     ],
     imports: [
       ...
       GeoDbProModule.forRoot({
         apiKey: YOUR_RAPID-API_KEY,
         serviceUri: https://wft-geo-db.p.rapidapi.com
       })
     ],
     bootstrap: [AppComponent]
   })
   export class SampleAppModule { }

Usage

In your Typescript class:

constructor(private geoDbService: DummyService) { }

Later on, in some method:

this.geoDbService.someMethod({
    someRequestParam: value,
    someOtherRequestParam: value,
    ...
  })
  .subscribe(
    (response: GeoResponse<TheResponsePayloadType>) => {
        // Do your thing!
      }
  )

            latitude: cityLocation.latitude,
            longitude: cityLocation.longitude,

          offset: 0
        })
        .subscribe(
          (citiesNearLocationResponse: GeoResponse<PlaceSummary[]>) => {
            const totalCount = citiesNearLocationResponse.metadata.totalCount;
            let data: PlaceSummary[] = citiesNearLocationResponse.data;

            // Do your thing!
        }
