During the month, contributed to the actualbudget/actual repository by enhancing the Query class API with new reset and serializeAsString methods. This work focused on improving API ergonomics, enabling state reset and string-based serialization to support persistence and diagnostics. The implementation aligned method definitions with TypeScript typings, reducing type-related runtime errors and maintaining backward compatibility for existing integrations. The approach demonstrated attention to API design, code maintenance, and adherence to TypeScript’s type discipline. JavaScript and TypeScript were used to ensure robust type safety and seamless integration. The changes expanded the Query class’s capabilities while minimizing risk for downstream consumers.
