Create Zustand stores following established patterns with proper TypeScript types and middleware.
Copy the template from assets/template.ts and replace placeholders:
{{StoreName}} → PascalCase store name (e.g., Project){{description}} → Brief description for JSDocimport { create } from 'zustand';
import { subscribeWithSelector } from 'zustand/middleware';
export const useMyStore = create<MyStore>()(
subscribeWithSelector((set, get) => ({
// state and actions
}))
);
export interface MyState {
items: Item[];
isLoading: boolean;
}
export interface MyActions {
addItem: (item: Item) => void;
loadItems: () => Promise<void>;
}
export type MyStore = MyState & MyActions;
// Good - only re-renders when `items` changes
const items = useMyStore((state) => state.items);
// Avoid - re-renders on any state change
const { items, isLoading } = useMyStore();
useMyStore.subscribe(
(state) => state.selectedId,
(selectedId) => console.log('Selected:', selectedId)
);
