Design Rationale

The Meme Generator with Trending Template Suggestions is designed to be user-friendly, scalable, and engaging. React was chosen for its component-based architecture, allowing for reusable UI elements and efficient updates. Node.js and Express provide a fast, lightweight backend that can handle concurrent requests efficiently.

The trending algorithm and caching system ensure that users always have access to the most popular templates, enhancing the app's appeal and relevance. Image processing libraries were selected to balance between powerful features and performance, enabling smooth meme creation on both desktop and mobile devices.

The database schema is designed to efficiently store user data, memes, and templates while allowing for quick retrieval and updates. The file structure separates concerns clearly, promoting maintainability and scalability as the project grows.

The deployment strategy focuses on reliability, scalability, and security, ensuring that the application can handle growing user bases and maintain high availability. Regular monitoring and updates will be crucial for maintaining the app's popularity and user satisfaction.
