@NgModule({

HalModule.forRoot()
]
})
export class AppModule {}
Inject Navigator
into components or services, then start retrieving HAL/JSON documents:
import { Navigator } from 'ng-hal';
@Injectable()
export class Foo {

this.navigator
.get('/my/hal-document.json')
.subscribe((doc: HalDocument) => console.log(doc));
}
}
Demo application
API Design Considerations
Navigator
API is almost identical to Angular'sHttp
API.follow
is a short-cut Observable operation that is derived frommergeMap
/flatMap
.
HalDocument
gives you aResource
object and the originalRequest
/Response
pair.Resource
is a normalized view of the JSON document. You can, however, obtain the unmodified JSON object.
