Worked on the pi-hole/web repository to enhance the stability of the DNS Records Settings interface by addressing API endpoint resolution issues. Focused on front end development using JavaScript, the solution replaced hardcoded relative API paths with a dynamic approach that constructs the base URL from document.body.dataset.apiurl. This adjustment ensures that the front end reliably communicates with the correct API endpoints across various deployment environments, including development, staging, and production. The change improved deployment consistency and reduced configuration drift, demonstrating proficiency in DOM manipulation and robust URL handling while maintaining compatibility with CI/CD workflows and existing code structure.
