King ICT E-commerce Application

Overview

This is a modern e-commerce application built with React and TypeScript, showcasing a responsive and user-friendly interface for browsing and purchasing products. The application demonstrates best practices in front-end development, state management, and API integration.

Main Features

  1. Product Catalog: Browse a wide range of products with detailed information.
  2. Search Functionality: Easily find products using the search bar.
  3. Category Filtering: Filter products by categories for a streamlined shopping experience.
  4. Price Range Filtering: Narrow down product selection based on price ranges.
  5. Sorting Options: Sort products by name or price, in ascending or descending order.
  6. Pagination: Navigate through multiple pages of products effortlessly.
  7. User Authentication: Secure login system for personalized user experiences.
  8. Responsive Design: Optimized for various screen sizes and devices.

Technologies Used

  • React 18.3
  • TypeScript 5.5
  • Vite 5.4 (for fast development and optimized builds)
  • React Router 6.26 (for client-side routing)
  • Tanstack Query 5.59 (for efficient data fetching, caching, and state management)
  • Axios (for API requests)
  • Tailwind CSS 3.4 (for styling)
  • Radix UI (for accessible UI components)
  • Lucide React (for icons)
  • ESLint (for code linting)

Architecture

The application follows a component-based architecture, leveraging React's composability. Key architectural decisions include:

  1. State Management: Utilizes Tanstack Query for server state management and custom hooks for local state.

  2. API Integration: Centralizes API calls in a dedicated service (ApiService) for better maintainability.

  3. Routing: Implements protected routes for authenticated sections of the app using React Router.

  4. Component Structure:

    • components/: Reusable UI components
    • pages/: Top-level components for each route
    • hooks/: Custom React hooks for shared logic
    • services/: API and other service-related code
    • lib/: Utility functions and helpers
  5. Styling: Adopts Tailwind CSS for utility-first styling, combined with custom components for consistent design.

Getting Started

  1. Clone the repository
  2. Install dependencies: npm install
  3. Start the development server: npm run dev
  4. Open http://localhost:3000 in your browser
  5. Login with the following credenials:
  • username: "emilys",
  • password: "emilyspass",

Building for Production

Run npm run build to create an optimized production build.

Continuous Integration and Deployment (CI/CD)

To maintain and upgrade the solution throughout its lifecycle, we recommend implementing the following CI/CD practices:

  1. Version Control: Use Git for source code management, with a branching strategy like GitFlow or GitHub Flow.

  2. Automated Testing:

    • Implement unit tests for components and utility functions.
    • Add integration tests for critical user flows.
    • Set up end-to-end tests using tools like Cypress or Playwright.
  3. Continuous Integration:

    • Use a CI service (e.g., GitHub Actions, GitLab CI, or Jenkins) to automatically run tests on every push or pull request.
    • Include linting and type-checking in the CI pipeline.
  4. Code Quality Checks:

    • Integrate static code analysis tools.
    • Set up code coverage reports.
    • Implement pull request reviews to maintain code quality.
  5. Continuous Deployment:

    • Automate deployments to staging environments for thorough testing.
    • Implement blue-green or canary deployments for production to minimize downtime and risk.
  6. Monitoring and Logging:

    • Set up error tracking (e.g., Sentry) to catch and diagnose issues quickly.
    • Implement application performance monitoring.
  7. Documentation:

    • Keep README and other documentation up-to-date with each significant change.
    • Use tools like Storybook for component documentation.
  8. Dependency Management:

    • Regularly update dependencies to patch security vulnerabilities and leverage new features.
    • Use tools like Dependabot for automated dependency updates.
  9. Environment Configuration:

    • Use environment variables for configuration to keep sensitive information secure.
    • Implement different configurations for development, staging, and production environments.

By following these practices, the application can be efficiently maintained, updated, and scaled over time, ensuring a robust and reliable user experience.
