# Zustand Store Create Zustand stores following established patterns with proper TypeScript types and middleware. ## Quick Start Copy the template from assets/template.ts and replace placeholders: - `{{StoreName}}` → PascalCase store name (e.g., `Project`) - `{{description}}` → Brief description for JSDoc ## Always Use subscribeWithSelector ```typescript import { create } from 'zustand'; import { subscribeWithSelector } from 'zustand/middleware'; export const useMyStore = create<MyStore>()( subscribeWithSelector((set, get) => ({ // state and actions })) ); ``` ## Separate State and Actions ```typescript export interface MyState { items: Item[]; isLoading: boolean; } export interface MyActions { addItem: (item: Item) => void; loadItems: () => Promise<void>; } export type MyStore = MyState & MyActions; ``` ## Use Individual Selectors ```typescript // Good - only re-renders when `items` changes const items = useMyStore((state) => state.items); // Avoid - re-renders on any state change const { items, isLoading } = useMyStore(); ``` ## Subscribe Outside React ```typescript useMyStore.subscribe( (state) => state.selectedId, (selectedId) => console.log('Selected:', selectedId) ); ``` ## Integration Steps 1. Create store in `src/frontend/src/store/` 2. Export from `src/frontend/src/store/index.ts` 3. Add tests in `src/frontend/src/store/*.test.ts` ## When to Use This skill is applicable to execute the workflow or actions described in the overview...
