Design Rationale

The design decisions for this project prioritize user engagement, real-time interaction, and scalability. React was chosen for the frontend due to its component-based architecture and large ecosystem, making it ideal for building interactive UIs. Node.js and Express provide a JavaScript-based backend that can handle real-time features efficiently.

PostgreSQL was selected as the primary database for its robustness and support for complex queries, which will be useful for analytics and social features. Redis is incorporated for caching and supporting real-time functionality, improving performance for frequently accessed data.

The use of WebSockets enables real-time updates crucial for the composting progress visualization and social interactions. The gamification elements are designed to increase user engagement and motivation, while the social features foster a sense of community among users.

The modular file structure and use of modern development tools like ESLint and Docker ensure maintainability and ease of deployment. The deployment strategy focuses on scalability and reliability, with continuous integration and monitoring to support the application's growth and stability.
