Worked on the OfficeDev/teams-toolkit repository to address a critical issue in Vite-based build configurations, focusing on improving runtime reliability across dashboard and SSO OBO flow templates. Using JavaScript and TypeScript, applied a targeted bug fix that standardized the global object reference to globalThis, eliminating inconsistencies that previously caused environment-specific runtime errors. This change stabilized the build process and enhanced developer productivity by ensuring consistent global access in all supported environments. The solution required minimal changes to the existing Vite configuration, resulting in more predictable deployments and smoother testing workflows without introducing unnecessary complexity or overhead to the codebase.
