Developed a structured domain management data model within the is-a-dev/register repository, focusing on configuration and data management using JSON. The work involved creating a new JSON file to store owner information and DNS records, establishing a consistent approach for handling domain data. Addressed a data-structure issue by converting the CNAME field from an array to a string, ensuring alignment with the expected schema and improving validation and downstream processing. This solution laid the groundwork for scalable domain management, reduced configuration errors during deployments, and streamlined onboarding for new users, demonstrating careful version control and collaborative development practices throughout the process.
