Why must Jotai atoms be defined outside of components?

Defining atoms inside a component's render cycle creates a new atom instance on every render, causing state to be lost and preventing data persistence across renders.

How does Jotai handle asynchronous data?

Jotai supports async atoms natively, which trigger React Suspense by default. You can also use utilities like loadable or unwrap for manual state handling without Suspense.

When should I use Jotai over standard React state?

Use Jotai for shared state that requires fine-grained reactivity, complex computed values with automatic updates, or whenever you need to avoid prop drilling in large component trees.

Should I use atomFamily from the core Jotai utils?

No, the core atomFamily is deprecated for new code. This skill recommends using the jotai-family package to ensure compatibility with future Jotai versions and better memory management.

Developer Tools

Implements fine-grained, atomic state management with automatic dependency tracking and React Suspense integration using Jotai.

This skill equips Claude with specialized knowledge to implement Jotai's bottom-up state management architecture, focusing on atomic consistency and optimized re-renders. It provides patterns for primitive, derived, and async atoms while enforcing critical best practices such as module-level atom definitions and proper Suspense boundary implementation to prevent common state corruption and runtime errors in modern React applications.
