TheerapatPooh developed a versioned checklist update feature for the TEAM6-DENSY repository, focusing on configuration integrity and safe production updates. They implemented the updateChecklist function in the Preset Controller using Express.js, Node.js, and Prisma, enabling the creation of new checklist versions with updated details and items while ensuring that only the latest version could be modified. Their approach included robust validation for required fields and verification of associated zone existence, addressing both data consistency and auditability. This work provided a structured method for managing checklist updates via REST API, reflecting a thoughtful and methodical approach to backend feature development.
