Project Workflow & Architecture

1. General Workflow

• The app is built with React (Vite) and uses Redux for state management and React Router for navigation.
• Components are organized by feature for scalability and maintainability.
• Pages are mapped to routes for navigation.
• Redux manages global state (cart, user, products, etc.).
• API calls are abstracted in the api/ folder.
• Custom hooks encapsulate business logic.

2. Redux State Management

• store/store.jsx: Configures the Redux store and applies middleware (e.g., thunk for async actions).
• actions/: Contains action creators for cart, product, and user. These dispatch actions to update the Redux state.
• reducers/: Contains slices (using Redux Toolkit or plain reducers) for product and user state. Each slice manages a part of the global state.
• Usage: Components use useSelector to read state and useDispatch to trigger actions. Example: useSelector(state => state.cart).

3. Routing

• routes/Mainroutes.jsx: Defines the main application routes using React Router v6+ (<Routes>, <Route>).
• routes/Auth.jsx: Handles routes that require authentication (e.g., user dashboard, settings).
• routes/Unauth.jsx: Handles routes for unauthenticated users (e.g., login, signup).
• pages/: Each page component is mapped to a route. Example: /cart renders pages/cart/Cart.jsx.
• Navigation: The Nav.jsx component provides navigation links using <NavLink>.

4. Component Structure

• components/: Contains all reusable UI components, grouped by feature (cart, filters, layout, etc.).
• pages/: Contains top-level pages for each route.
• hooks/: Contains custom React hooks for encapsulating logic (e.g., cart logic, product fetching).

5. API Layer

• api/config.jsx: Centralizes API endpoints and HTTP logic (e.g., using axios or fetch). All network requests are made through this layer for consistency.

6. Styling

• index.css: Global styles. Components may use Tailwind CSS or other utility classes for styling.

7. Development & Contribution

• Run npm install to install dependencies.
• Use npm run dev to start the development server.
• Lint code with npm run lint.
• Follow the folder structure and naming conventions for new components/pages.

Key Concepts for New Users

Redux

• Redux is used for global state management (cart, user, products, etc.).
• Actions are dispatched to update state; reducers handle the logic.
• Use useSelector to access state and useDispatch to trigger actions in components.

Routing

• React Router is used for client-side navigation.
• Define routes in routes/ and map them to page components.
• Use <NavLink> for navigation links.

Adding New Features

• Add new UI components in components/.
• Add new pages in pages/ and map them in routes/.
• Add new Redux state by creating a new slice in store/reducers/ and updating store.jsx.

API Calls

• Use functions from api/config.jsx for all HTTP requests.
• Keep API logic out of components for maintainability.

Custom Hooks

• Place reusable logic in hooks/ (e.g., useCart).
