# 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.
