Developed a collaborative editing feature for the facebook/lexical repository, enabling real-time rendering of user cursors and selections using the CSS Custom Highlight API. This work integrated Lexical-YJS for CRDT-based presence and Lexical-React for seamless React application support, allowing multiple users to see visually distinct cursors during live editing sessions. The implementation focused on performance-conscious UI rendering and robust integration testing to ensure a smooth user experience. Utilizing JavaScript and TypeScript, the feature improved editing precision and reduced conflicts, laying the foundation for enhanced presence features and supporting more intuitive multi-user workflows in collaborative front end environments.
