SYSTEM DOCUMENTATION & REQUIREMENTS

## What problem does it solve? This Skill enables React developers to implement robust, reactive state management using Effect Atom, providing stable references, automatic cleanup, and lazy evaluation for complex component lifecycles.

## Core Features & Use Cases

  • Atoms as stable references that share state across components.
  • Derived atoms via map and computed getters to derive state without wiring props.
  • Atom.fn for async actions with built-in waiting state and Result handling.
  • Runtime integration with services to access shared layers and centralize side effects.
  • Persistence and scoped effects with automatic cleanup to prevent leaks.
  • Use Case: Build a dashboard with shared counters and derived summaries across components.

### Quick Start Install the library packages, create a simple atom with Atom.make, and use it inside a React component via hooks like useAtomValue and useAtomSet. export const count = Atom.make(0) function Counter() { const [value, setValue] = useAtom(count) return <button onClick={() => setValue(value + 1)}>{value}</button> }

FAQPage Schema
How do I manage reactive state in React with automatic cleanup and lazy evaluation?

Reactive state management in React uses Effect Atom to provide stable references, automatic cleanup, and lazy evaluation for complex component lifecycles. Atoms share state across components without prop drilling.

What is the best way to derive state in React without wiring props?

Derived state in React uses Atom.map and computed getters to calculate values reactively from existing atoms. This approach derives state without wiring props, ensuring components only re-render when dependencies change.

How do I handle asynchronous actions in React state management with a waiting state?

Asynchronous actions in React state management use Atom.fn to handle async logic with built-in waiting state and Result handling. This tracks loading statuses and manages success or failure outcomes within the state architecture.

Can I integrate a service layer with React state management using Effect Atom?

Effect Atom integrates service layers via Atom.runtime to access shared layers and centralize side effects in a modular React architecture. This separates business logic from UI components while maintaining reactive state updates.

How do I create a simple shared atom in a React component?

Create a shared atom using Atom.make to define initial state, then access it inside a React component via hooks like useAtomValue and useAtomSet. This provides stable references that share state across multiple components.

Does Effect Atom prevent memory leaks in React applications?

Effect Atom prevents memory leaks through scoped effects with automatic cleanup. It manages complex component lifecycles by automatically cleaning up subscriptions and side effects when components unmount.
