Repository Pattern & Read/Write Separation for Zoo Service — Analysis

Context

Alex suggested introducing the repository pattern and clearer read/write transaction separation for the Zoo backend service. This analysis evaluates the benefits, costs, and whether it's worth doing now vs. later.

Current State of Zoo

JetStream vs Core NATS for Zoo Streams — Analysis

Infra tooling is ready: jetstream-writer, jetstream-reader, registry, AsyncAPI contracts

What JetStream Adds

Svelte Lazy Loading Components: Svelte 4 vs Svelte 5 (Runes)

Description

This gist demonstrates how to lazy load Svelte components using dynamic imports, comparing the syntax between Svelte 4 and Svelte 5 (runes mode). Lazy loading is a powerful technique to optimize bundle size and improve performance by loading components only when needed (e.g., widgets, modals, or rarely-used UI).
