During March 2025, Fa focused on stabilizing the dcloudio/uni-app repository by addressing issues with the experimental HarmonyOS mini-program Vue 3 integration. Using JavaScript and TypeScript, Fa executed a comprehensive rollback, removing the uni-mp-harmony directory and related files to revert the codebase to a previously stable state. This work emphasized code reversion and rollback skills, ensuring that unstable features did not impact ongoing development. Fa documented the rationale for these changes and validated the resulting builds, maintaining repository reliability. The effort prioritized maintainability and predictable delivery, setting a solid foundation for future mini program development and integration work.
