Authentication

• Secure authentication implementation with Google OAuth 2.0, using token-based authorization flow to validate the user's identity without storing sensitive credentials in the backend.
• User data such as email, name, and profile picture are extracted and processed in the ASP.NET Core backend, ensuring fast and secure access to the platform.
• Integration with Google's identity service to verify email authenticity and enhance security through the use of JWT (JSON Web Token) and custom claims.
• Integration of Identity for user and role management.

Export to PDF

• Dynamic generation of PDF documents for the shopping list, organized by days and categories, optimizing user experience.
• Implementation of OpenHTMLToPDF for HTML-to-PDF conversion with custom styles and rendering optimization.
• The backend, developed in ASP.NET Core, receives a request from the frontend to export the list to PDF. It uses a specialized service, ViewRenderer, which utilizes ICompositeViewEngine to render Razor HTML templates and generate structured content.
• Use of Razor Templates to dynamically define the structure and styles of the PDF, ensuring compatibility and flexibility in design.

Share List

• Implementation of a sharing feature with unique links, generated with secure unique identifiers (UUID), allowing real-time collaboration.

Add Groceries

• Advanced grocery creation form, with real-time validation and user experience improvements using ReactiveFormsModule from Angular.
• Ability to add custom products with name, description, image, link, and category, ensuring flexibility in managing the shopping list.
• Editing and deleting products with visual confirmations, ensuring better user interaction.
• Optimized data persistence with Entity Framework Core in the backend, ensuring secure and efficient transactions.

Lists for Every Occasion

• Creation and management of multiple categorized shopping lists for different events or needs.

Receipt

• Automatic generation of a detailed receipt with breakdown of costs for each product and total amount.
• Advanced currency formatting and number presentation using Angular's currency pipe from CommonModule on the frontend to enhance clarity of the information.

This project is developed with an architecture based on Angular 19 on the frontend and ASP.NET Core on the backend, ensuring scalability, performance, and enterprise-level maintainability.
