useState for component-scoped state (forms, UI toggles).@tanstack/react-query for API data (caching, refetching).const ThemeContext = createContext<ThemeContextType | undefined>(undefined);
export function useTheme() {
const ctx = useContext(ThemeContext);
if (!ctx) throw new Error('useTheme must be inside ThemeProvider');
return ctx;
}
import { create } from 'zustand';
const useStore = create((set) => ({
count: 0,
increment: () => set((state) => ({ count: state.count + 1 })),
}));
// Usage
const count = useStore((state) => state.count);
