Worked on enhancing the desktop messaging experience for the moeru-ai/airi repository by implementing an Enter-to-Submit feature tailored for desktop users. Leveraged Vue.js and JavaScript to detect device context, ensuring that message submission via the Enter key is enabled only on non-mobile platforms. This approach introduced isMobileDevice detection to route submission calls appropriately, preventing unintended behavior on mobile devices and aligning desktop functionality with mobile standards. The update improved cross-platform parity and streamlined the submission flow, reducing friction for desktop users. Focus remained on frontend development, emphasizing user experience improvements and responsive design within the existing Vue-based architecture.
