During November 2024, Toni Tertsonen focused on enhancing the reliability of external API integrations in the Tietokilta/web repository by improving error handling for the Laskugeneraattori service. Toni introduced an ErrorResponse interface and a tryParse function in TypeScript to robustly parse and structure JSON error responses, ensuring that errors from the external API were consistently captured and reported. This targeted bug fix reduced investigation time and streamlined debugging without introducing risk to existing functionality. By leveraging skills in API integration, error handling, and TypeScript development, Toni maintained code quality and alignment with established patterns in the project’s web codebase.
