To build a reactive Nostr client, initialize an EventStore and create a TimelineQuery for a given pubkey. This setup allows you to manage Nostr data reactively, enabling real-time updates for feeds and profiles.

The best way to create a real-time Nostr timeline feed is by using applesauce-core's timeline utilities. By setting up a TimelineQuery, you can observe Nostr events reactively, ensuring your feed updates automatically as new events arrive.

Yes, applesauce-core integrates with RxJS to manage reactive Nostr data streams. You can use observables to handle event store updates, queries, and timeline changes, ensuring your Nostr application updates reactively to new data.

To set up a minimal applesauce-core example, install the package and initialize an EventStore. Then, create a basic TimelineQuery for a specific pubkey to start observing and displaying Nostr events reactively in your application.

You need observables for Nostr event queries when you want your application to react automatically to new data. Using applesauce-core, observables allow your event stores and timeline queries to push real-time updates to the UI without manual polling.

A limitation of reactive event stores is the potential for high memory consumption when managing large volumes of Nostr events. You must carefully manage query subscriptions and observable disposal to prevent performance bottlenecks in your Nostr client.
