概要

Nanostores is a minimal (<1KB) state management library for JavaScript. No boilerplate, no actions/reducers, just atoms (observable values) and computed state. Works with React, Vue, Svelte, Solid, Angular. Mastery takes 1-2 weeks. Ideal for small-to-medium apps, embedded widgets, or when Redux/Zustand feels overkill. Teams using Nanostores report 50% reduction in state-management boilerplate and faster onboarding. Scarcity is low; learning curve is so low it's almost irrelevant, but knowledge is uncommon outside of performance-conscious teams.

Nanostores Tinyとは

Nanostores is a minimal state management library (<1KB bundled). You create stores as atoms (observable values) and computed stores (derived state). Components subscribe to stores and re-render when store values change. No actions, reducers, or boilerplate, just plain functions. Example: atom(0) creates a counter. counter.set(5) updates it. Components using useAtom(counter) re-render when counter changes. Computed stores combine atoms: computed([countA, countB], (a, b) => a + b).

❓ よくある質問

When should I use Nanostores instead of Redux or Zustand?

Redux: enterprise apps with complex logic, time-travel debugging. Zustand: medium apps, good dev experience. Nanostores: small apps, widgets, library code. Size matters: Redux ~45KB, Zustand ~2KB, Nanostores <1KB. For a simple app or component library, Nanostores wins. For teams that grew Redux, migrate to Nanostores as you simplify.

Can Nanostores replace Context API?

Yes, better. Context = re-renders all consumers. Nanostores = fine-grained subscriptions, only affected consumers re-render. Both are unrelated to component tree. Nanostores = less boilerplate (no Provider, no useContext hook chain). Prefer Nanostores for app-level state.

How do I handle async operations?

Use computed stores that depend on async values. Example: atom(initialValue) → onMount(() => fetch data → atom.set(data)). No special async syntax, just plain JS. For complex async workflows, pair with tRPC or React Query.

Is Nanostores suitable for large apps?

Yes, but structure matters. Use many small atoms (one per concern) vs. one mega-atom. Don't use Nanostores for highly interactive, client-side complex state (game engine, real-time collab). Use for app chrome, routing, user preferences. Pair with Query for server state.

How do I debug Nanostores?

Subscribe to stores and log changes. Example: `atom.subscribe(value => console.log(value))`. No devtools yet (unlike Redux), but logging is simple. For complex debugging, migrate to Zustand (has devtools).
