Developed a configurable transport protocol feature for the decolua/9router repository, enabling deployment-time selection between http2, quic, or an automatic mode, with http2 as the default. This work focused on backend development and configuration management using Node.js and JavaScript, introducing an environment-driven approach that allows operators to tailor tunnel behavior without code changes. The implementation established a clean extension point, making it straightforward to support additional protocols in the future. By integrating this feature, the codebase now supports greater flexibility and maintainability, addressing evolving deployment needs while minimizing the effort required to introduce new transport protocol options.
