Worked on the TheerapatPooh/TEAM6-DENSY repository to deliver versioned update capability for checklist presets, focusing on enhancing configuration integrity and auditability. Developed the updateChecklist function within the Preset Controller using Express.js, Node.js, and Prisma, enabling updates to checklists by creating new versions with revised details and items. The implementation enforced that only the latest checklist version could be modified, ensuring safety and consistency in production environments. Comprehensive validations were added to check for required fields and the existence of associated zones, supporting robust REST API design. This work improved traceability and safeguarded production updates through structured version control.
