PROFILE
Anders Jansson
Worked on the facebook/react-native repository to enhance error handling for React Native applications using Hermes by introducing TypeScript typings support for the Error.cause property. Addressed a longstanding gap by updating TypeScript lib options to include es2022.error, enabling seamless use of error.cause without type errors. Verified the solution locally by updating tsconfig settings and confirming type-checking compatibility. Documented the change through changelog updates and coordinated the pull request workflow. This work leveraged TypeScript, error handling best practices, and integration with Hermes, ultimately reducing friction for developers and improving error reporting and debugging across JavaScript and TypeScript boundaries in React Native projects.

May 1, 2026May 2026: Focused on strengthening TypeScript typings for error handling in Hermes-enabled React Native. Key feature delivered: TypeScript typings support for the Error.cause property, enabling use of error.cause without TypeScript errors. Implemented by adding es2022.error to the TypeScript lib options, aligning with Hermes support since 2021. The change is backed by commit abcb7821b1e43ba5ff0ec92c746e6fbc4b2a10f3 and associated work around PR 56968. Test Plan: local verification updating tsconfig/lib options to es2022.error and confirming type-check passes. Documentation/changelog: [GENERAL] [ADDED] - Add TypeScript support for Error `cause` property; PR D106364666 and related PR 56968; changes shipped with fabriziocucci and bshipit. Impact/Value: reduces TypeScript friction for RN apps using Hermes, improves error reporting and debugging across the JS/TS boundary. Technologies/Skills Demonstrated: TypeScript lib options, TS type augmentation, Hermes integration, PR workflow, changelog propagation.
