Worked on enhancing the Sitecore/jss repository by developing an event-driven feature for the component library, aimed at improving editor responsiveness and reliability. Implemented logic in JavaScript and TypeScript to emit a render event whenever a component update occurs, ensuring the editing environment remains synchronized with component changes. Refactored the update handling process to reliably trigger these events, addressing potential synchronization gaps. Expanded automated test coverage to strengthen reliability and reduce regression risk, focusing on component library interactions. The work leveraged skills in component development, event handling, and front-end testing, laying a foundation for future automation and improved editing guidance.
