Zustand state management for React and vanilla JavaScript. Use when creating stores, using selectors, persisting state to localStorage, integrating devtools, or managing global state without Redux complexity. Triggers on zustand, create(), createStore, useStore, persist, devtools, immer middleware.
Share a single global instance throughout your application to manage global state.
Practical immutability patterns in TypeScript - spread operators, nested updates, readonly types, and when mutation is actually fine
Production-tested setup for Zustand state management in React applications with TypeScript. This skill provides comprehensive patterns for building scalable, type-safe global state. Use when: setting up global state in React, migrating from Redux or Context API, implementing state persistence with localStorage, configuring TypeScript with Zustand, using slices pattern for modular stores, adding devtools middleware for debugging, handling Next.js SSR hydration, or encountering hydration errors, TypeScript inference issues, or persist middleware problems. Prevents 5 documented issues: Next.js hydration mismatches, TypeScript double parentheses syntax errors, persist middleware export errors, infinite render loops, and slices pattern type inference failures. Keywords: zustand, state management, React state, TypeScript state, persist middleware, devtools, slices pattern, global state, React hooks, create store, useBoundStore, StateCreator, hydration error, text content mismatch, infinite render, localStorage, sessionStorage, immer middleware, shallow equality, selector pattern, zustand v5
Zustand 5 state management patterns for React: stores, persistence, selectors, slices. Trigger: When managing global state in React, using Zustand, or implementing state slices.
Zustand 5.x state management with slices, middleware, Immer, useShallow, and persistence patterns for React applications. Use when building state management with Zustand.
Zustand 5 state management patterns. Trigger: When managing React state with Zustand.
Zustand v5 state management for React. Use when implementing global state, stores, persist, or client-side state.
Production-tested setup for Zustand state management in React. Includes patterns for persistence, devtools, and TypeScript patterns. Prevents hydration mismatches and render loops.
XState Store adapter for json-render's StateStore interface. Use when integrating json-render with @xstate/store for state management via @json-render/xstate.
Jotai状態管理ライブラリのエキスパートスキル。Reactアプリケーションでのatomベースの状態管理を実装する際に使用。以下の場合にこのスキルを使用: (1) Jotaiのatom設計・実装 (2) 派生atom、非同期atom、atomFamilyの実装 (3) Jotaiのベストプラクティスに基づくリファクタリング (4) パフォーマンス最適化（selectAtom、splitAtom等） (5) 永続化（localStorage/sessionStorage連携） (6) TypeScript型定義 (7) テスト実装 ユーザーが「Jotai」「atom」「状態管理」に関する質問や実装依頼をした場合に発動。
