Modern Tooling and Project Structure

The project uses Vite for fast development and builds, Tailwind CSS for styling, ESLint for code quality, and React Router for navigation. Modern JavaScript practices like ES modules and React Context API enhance performance and maintainability.

Component-Level Architecture

Application Entry Point and Routing

`src/main.jsx` is the React entry point. `src/App.jsx` handles routing with React Router v7 and global authentication context from `src/contexts/SessionContext.js`. This avoids prop drilling and enables route protection.

Authentication and Session Management

Sign-in and sign-up pages (`SignInPage.jsx`, `SignUpPage.jsx`) use shared components (AuthForm, FormContainer) for consistent forms and validation. Session tokens are stored in local storage. React Context provides global session access, enabling auto-redirection, secure API calls, and immediate state updates.

Data Fetching and API Integration

`src/services/apiFetch.js` centralizes backend communication, injecting auth headers and handling JSON. Service modules (`plant.js`, `user.js`, `cart.js`) wrap API endpoints. This makes network code reusable, testable, and maintainable.

Plant Listings and Detailed Views

Plant List Page:

`PlantListPage/index.jsx` fetches plant data and renders a grid. `PlantItem.jsx` displays each card with dynamic pot colors. `utils.js` provides random image selection.

Plant Details Page:

`PlantShowPage/index.jsx` composes sub-components (PlantHeading, BenefitBox, PlantInfoSection, PlantPurchaseOptions) for product info, care instructions, and purchase options. Framer Motion adds smooth animations.

Navigation and Shared Components

NavBar (`NavBar/index.jsx`) displays user info, sign-out, and cart modals. Spinner and ScrollToTop handle async operations and route transitions.

State Management and Responsiveness

State management uses React hooks and Context API. Components maintain local state for loading and forms. Global session state ensures consistent authentication.

Tailwind CSS provides responsive layouts for mobile and desktop.

Final Thoughts

Rica's Plants demonstrates modern frontend architecture: component-based design, efficient API integration, and global state management create a scalable, maintainable application.
