Worked on the OpenWrt LuCI repository to improve the stability and robustness of the BanIP feature’s user interface. Addressed a critical bug in overview.js by implementing safe handling for missing or undefined feed data, specifically resolving a Trim() error that previously caused the BanIP Overview tab to fail to open or display correctly. This solution involved careful JavaScript front-end development, ensuring that feed keys, chains, and descriptions are trimmed only when valid. The update reduced UI failures and improved the overall user experience, while also lowering support overhead related to BanIP data presentation and runtime errors in the interface.
