What problem does it solve?

Effect Atom state management removes the friction of building reliable, type-safe, reactive UI state in React by letting you model state as stable Atom references with built-in async handling and cleanup.

Core Features & Use Cases

• Reactive atoms by reference: create shared, stable state containers that automatically update all subscribed components when values change.
• Derived and async atom patterns: compose derived state via computed atoms, and handle async effects safely using Atom.fn with AsyncResult waiting/success/error states.
• React integration with scoped lifecycle cleanup: manage external resources and subscriptions with finalizers and atom scoping so state doesn’t leak.

Quick Start

Create an Atom (or Atom.fn for async operations) that represents your state or Effect-based action, then wire it into React using the appropriate hooks from @effect/atom-react.
