Worked on frontend improvements in the scaleway/ultraviolet repository, focusing on enhancing the CodeEditor component by introducing a configurable lineNumbers prop. This feature allowed users to toggle the display of line numbers, with the default set to true to maintain existing user experience and ensure backward compatibility. The implementation emphasized code quality, maintainability, and clear traceability through focused pull requests and commit messages. Using React, JavaScript, and TypeScript, the work prioritized stable releases and non-breaking changes, addressing user interface flexibility without introducing bugs. The approach demonstrated attention to detail in component development and a commitment to robust, maintainable front-end code.
