March 2025 performance highlights for mxcube/mxcubeweb focused on security hardening, robustness, and improved user experience in hardware configuration workflows. Key outcomes include a security posture upgrade via a Secure by Default CORS configuration and a resilience improvement for sample list retrieval when the hardware object is not loaded, together delivering smoother authentication flows and reduced user friction. Impact and value: - Security: Default strict CORS reduces cross-site exposure, aligning with best practices and reducing potential attack surface. - Reliability: Graceful handling of missing hardware objects prevents broken user flows and supports edge cases in hardware configurations. - UX: Preserves redirect flow after authentication and minimizes user-facing errors, improving overall usability for MXCuBE-Web. - Maintainability: Changes are isolated to configuration and error-handling paths, with clear commit messages enabling easier future audits. Technologies/skills demonstrated: - Security-conscious backend configuration (CORS) and environment-aware defaults - Robust error handling and graceful degradation in presence of hardware state variations - Authentication flow handling and user experience considerations - Code baselining with minimal surface area for future enhancements
