PROFILE
Jo Arroyo
Worked on the AzureAD/microsoft-authentication-library-for-js repository, delivering features and fixes that improved authentication reliability, security, and developer experience across Angular and React integrations. Focused on compatibility upgrades, such as supporting Angular 19 and 21 as well as React 16 through 18, while modernizing sample applications and documentation to accelerate onboarding. Addressed token expiration edge cases by standardizing time handling with new utilities in TypeScript and JavaScript. Enhanced security by updating dependencies and introducing stricter defaults for authentication interceptors. Contributed to API design, code refactoring, and CI/CD improvements, ensuring forward compatibility and reducing migration friction for downstream applications and users.

Mar 1, 2025March 2025 monthly summary for AzureAD/microsoft-authentication-library-for-js: Delivered reliability and standardization improvements focused on token expiration handling and cross-package time conversions. Key outcomes include a bug fix in NativeBrokerPlugin for expiresOn calculation and the introduction of a centralized TimeUtils utility across msal-browser, msal-common, and msal-node-extensions, with corresponding unit tests updated. These changes reduce token expiration edge-case risks, improve developer experience, and enable more maintainable time-handling across the library, supporting smoother authentication flows and fewer customer-facing errors.
