The Web Shop project aims to create a fully functional e-commerce website where users can browse products, add them to their cart, and make purchases. This project will be developed by two interns, one focusing on frontend development using React, and the other on backend development using Java with the Spring Framework.

This documentation serves as a comprehensive guide for the interns working on this project. It outlines the key concepts and tasks they should cover during their development work, ensuring that the final product is well-structured, secure, and meets the requirements of a typical web shop application.

This documentation is intended for the two interns who will be working on the project. It will help them understand their roles and responsibilities, as well as provide guidance on implementing various aspects of the web shop application.

• Set up a new React project using Create React App or an equivalent tool.
• Organize the project structure for scalability and maintainability.

• Create responsive and user-friendly UI components for product listing, cart, checkout, and user account management.
• Implement a consistent and visually appealing design.

• Use state management libraries like Redux or Context API for managing application state.
• Ensure efficient data flow between components.

• Fetch product data from the backend API.
• Implement user authentication and authorization flows.

• Set up routing using React Router or a similar library.
• Implement navigation between different sections of the web shop.

• Organize components into a logical hierarchy.
• Create reusable components for common UI elements.

• Implement error handling for network requests and user interactions.
• Display informative error messages to users.

• Write unit tests for components and integration tests for user flows.
• Ensure code coverage and reliability.

• Deploy the React frontend to a hosting platform (e.g., Netlify, Vercel).
• Set up continuous integration and deployment (CI/CD) pipelines if possible.

• Create a new Spring Boot project.
• Configure the project for Java development.

• Implement Create, Read, Update, and Delete (CRUD) operations for products and user data.

• Implement JWT-based authentication and authorization for users.
• Secure API endpoints to prevent unauthorized access.

• Hash user passwords securely before storing them in the database.
• Implement password validation and reset functionality.

• Configure logging using a logging framework like Log4j or SLF4J.
• Log relevant information for debugging and monitoring.

• Set up a connection to a PostgreSQL database.
• Define database schemas and tables for products and user data.

• Use a database migration tool (e.g., Flyway) to manage database schema changes.
• Ensure smooth database updates and version control.

• Create custom exception classes for handling specific error scenarios.
• Implement global exception handling for consistent error responses.

• Implement the repository pattern to interact with the database.
• Separate data access code from business logic.

• Define consistent HTTP response entities for success and error responses.
• Use appropriate status codes and error messages.

This software documentation provides a comprehensive overview of the Web Shop project, detailing the responsibilities of the two interns working on the frontend and backend development. By following the guidelines and concepts outlined in this document, the interns can create a secure, scalable, and fully functional e-commerce website.

In the future, additional features and improvements can be made to enhance the web shop, such as implementing payment processing, user reviews, product recommendations, and more. Regular maintenance and updates should also be considered to ensure the continued success of the application.
