Worked on the kenzok8/sublink-worker repository to deliver default UDP support for Clash proxies, focusing on backend development with Node.js and JavaScript. The approach involved introducing a centralized function to retrieve UDP values and updating the ClashConfigBuilder to consume this function, standardizing UDP handling across proxy configurations. This change reduced configuration friction and improved the reliability of UDP proxy sessions, directly enhancing system stability. The work included a bug fix to enable UDP by default, and was co-authored in collaboration with another developer, demonstrating effective teamwork and adherence to strong code quality practices throughout the feature’s implementation and delivery.
