Beginner's Tutorial

Welcome to the Applesauce tutorial! This step-by-step guide will teach you how to build reactive Nostr applications using the applesauce library ecosystem.

What You'll Learn

By the end of this tutorial, you'll understand how to:

• Set up an in-memory reactive database for Nostr events
• Parse and display user profiles and content
• Create reactive UI components that respond to data changes
• Connect to Nostr relays and subscribe to events
• Create and publish new Nostr events

This tutorial is broken down into digestible sections:

1. Introduction to EventStore - Learn about the reactive database at the heart of applesauce
2. Working with Helpers - Parse profiles and extract data from events
3. Building Reactive UI with Models - Create React components that respond to data changes
4. Connecting to Relays - Subscribe to Nostr relays and receive events
5. Loading Specific Events with Loaders - Load specific events from relays
6. Creating Events with EventFactory - Set up event creation and signing
7. Publishing Events - Publish events to relays and handle responses
8. Using Actions - Run complex actions like following users

Prerequisites

• Basic knowledge of JavaScript/TypeScript
• Familiarity with React hooks (useState, useEffect)
• Understanding of RxJS observables (helpful but not required)
