Over a two-month period, this developer focused on enhancing build stability and server reliability across eesast/web and eesast/THUAI8. In eesast/web, they refactored dependency management using JavaScript and Yarn, ensuring a consistent @antv/g2 version by centralizing resolution in yarn.lock and aligning related packages to prevent conflicts and CI failures. For eesast/THUAI8, they improved game server startup reliability with Shell scripting and C#, addressing run.sh issues, exposing server status, and refining failure detection. Their work emphasized configuration management and dependency resolution, resulting in more reliable builds and streamlined server operations without introducing new bugs during the development cycle.
