Worked on enhancing the BettaFish frontend by addressing a network accessibility issue that affected cross-device collaboration. Focused on frontend development and network configuration, the solution involved replacing hardcoded localhost URLs with dynamic host resolution using window.location.hostname for both iframe sources and search endpoints. This adjustment allowed devices on the same local network to access backend services without manual URL changes, streamlining testing and reducing setup complexity. The update was implemented in the 666ghj/BettaFish repository using HTML and JavaScript, and was merged with a clear, isolated scope to minimize risk while improving reliability and accessibility for users across multiple devices.
