SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Applesauce-core enables developers to build reactive Nostr clients by providing a comprehensive set of libraries and patterns for event stores, queries, observables, and profile helpers.

Core Features & Use Cases

Core features include EventStore management, declarative queries, RxJS-based observables, timeline utilities, profile helpers, and NIP helpers, enabling real-time timelines, replaceable events handling, and efficient data access in feeds and profiles.

Quick Start

Install the library via npm, import the core components, and set up a minimal reactive workflow: create an EventStore, create a timeline query, and subscribe to the events observable to render a live feed.

FAQPage Schema

How do I build a reactive Nostr client with real-time timeline updates?▼

Build a reactive Nostr client using applesauce-core patterns for event stores, queries, and observables. You create an EventStore, set up a timeline query, and subscribe to the events observable to render a live feed with real-time updates.

What is the best way to manage Nostr event stores and declarative queries in TypeScript?▼

Manage Nostr event stores and declarative queries using applesauce-core, which provides specialized helpers for event store management and efficient data access. This allows you to handle replaceable events and query feeds reactively.

How do RxJS observables work with Nostr profile helpers and timeline utilities?▼

RxJS observables work with Nostr profile helpers and timeline utilities by subscribing to event store changes, enabling reactive updates in feeds and profiles. Applesauce-core applies these patterns to deliver declarative queries and real-time data access.

Do I need specific npm tooling to integrate reactive Nostr patterns into my project?▼

You need standard npm tooling and applesauce-core v5 installation to integrate reactive Nostr patterns into your project. Once installed, import the core components to set up a minimal reactive workflow for your application.

Can I handle replaceable events and NIP helpers using reactive Nostr event stores?▼

Handle replaceable events and NIP helpers using reactive Nostr event stores provided by applesauce-core. The library includes specific helpers for these Nostr Implementation Possibilities, ensuring efficient data access within feeds and profiles.

What are the limitations of using reactive observables for Nostr timelines?▼

Limitations of using reactive observables for Nostr timelines include the need to manage RxJS subscription lifecycles manually to avoid memory leaks. Developers must also ensure their project environment supports the required applesauce-core v5 dependency.
