Show HN: Reusable UI components via property-level state with React and Jotai

2•ivanglpz•3w ago
This work is implemented using React with Next.js, React Konva for canvas-based rendering, and Jotai as the state management layer.

The core architectural decision is to model UI elements using property-level state separation instead of a single monolithic state per element. Each relevant property is represented as an independent atom, which significantly reduces unnecessary React re-renders. Only the properties that actually change trigger updates, rather than invalidating the entire element state.

This architecture was introduced recently to enable new functionality without increasing state complexity or processing overhead. The reusable component mechanism described here is a direct consequence of that design.

When an element is reused, the copied instance does not duplicate state. Instead, it stores only the identifier of the source element. At render time, the copied instance resolves the source element’s properties dynamically using that identifier. Because state is separated by property, updates remain synchronized without shared mutable state or redundant updates.

If the referenced source element is removed, the system falls back to the original element definition. This avoids broken references and ensures predictable behavior across element lifecycle changes.

For visual context, a short demo video is available here: https://x.com/ivanglpz/status/2012169953168838940?s=20

This approach results in reduced rendering overhead, clear separation of responsibilities, and a scalable foundation for building synchronized, reusable UI components.
