Integration Complexity: Combining Rust for backend and Next.jsfor frontend requires careful handling of communication between the two, ensuring seamless data flow and performance optimization. Performance Optimization: Real-time photo manipulation demands high computational power and efficient resource management to maintain smooth user experiences without lag. Cross-Platform Development: Developing a consistent and high-quality user experience across both web-based and desktop applications involves addressing different platform-specific requirements and potential compatibility issues. User Interface Design: Creating an intuitive and responsive node-based interface requires extensive user testing and iterative design improvements to ensure it meets user expectations and usability standards. Error Handling: Ensuring robust error handling and recovery mechanisms to handle unexpected user actions and maintain application stability. Security Concerns: Managing data securely, especially in a real-time application, to protect user privacy and prevent unauthorized access or data breaches.
