| Principle | Description | |-----------|-------------| | | UI components should not know about data fetching or business logic. | | Single Responsibility | Each file/folder should have one reason to change. | | Dependency Inversion | High-level modules (pages) should not depend on low-level modules (API utils). Both should depend on abstractions (hooks/services). | | Colocation | Keep styles, tests, and utilities close to the components that use them. | | Lazy Loading | Never load code the user doesn't need immediately. | 3. Folder Structure by Features Avoid organizing by file type (e.g., components/ , containers/ , services/ ). Instead, use feature-based organization : react application architecture for production pdf

Use route -level code splitting with webpackChunkName or Vite's automatic naming. 7. Styling and Theming For production, choose one consistent approach. Recommendation: CSS Modules + CSS Variables for theming. Global theme tokens /* app/styles/theme.css */ :root --color-primary: #3b82f6; --color-background: #ffffff; --spacing-md: 1rem; --border-radius: 0.5rem; Both should depend on abstractions (hooks/services)

export const useAuthStore = create<AuthStore>((set) => ( user: null, isAuthenticated: false, login: (user) => set( user, isAuthenticated: true ), logout: () => set( user: null, isAuthenticated: false ), )); Never call fetch or axios directly inside a component. Build a structured data layer: export const useAuthStore = create&lt

No jumping across 20 directories. 4. State Management Strategy Production apps require a layered state strategy :
