The DeliveryObservableProxy class provides a reactive way of retrieving content from Kontent.
The DeliveryObservableProxy class constructor accepts an IDeliveryClient instance, therefore you are free to create the IDeliveryClient implementation (or its derivatives) in any of the supported ways.
public IDeliveryClient DeliveryClient => DeliveryClientBuilder.WithEnvironmentId("975bf280-fd91-488c-994c-2f04416e5ee3").Build();
public DeliveryObservableProxy DeliveryObservableProxy => new DeliveryObservableProxy(DeliveryClient);
The DeliveryObservableProxy class exposes methods that mirror the public methods of the IDeliveryClient. The methods have the same names, with an Observable suffix. They call the IDeliveryClient methods in the background.
IObservable<Article> articlesWithBaristaPersona =
DeliveryObservableProxy.GetItemsObservable<Article>(new ContainsFilter("elements.personas", "barista"));
Unlike most of the IDeliveryClient methods that return data wrapped in IDelivery*Response objects, their *Observable counterparts always return sequences of the Kontent.ai artifacts themselves (not wrapped). Should an error response be returned by the IDeliveryClient implementation, the observable sequence will terminate with the conventional OnError call.
