PROFILE
Dixon Yant
Worked extensively on the Esri/arcgis-rest-js repository, delivering new features and modernizing the testing and CI infrastructure over seven months. Led the migration of test suites from Jasmine/Karma to Vitest, improving reliability and feedback speed. Enhanced the Query API with robust error handling, 3D geometry support, and PBF format integration for efficient geospatial data processing. Implemented deprecation messaging and suppression mechanisms to guide developers and reduce console noise. Contributed to code quality through refactoring, dependency management, and improved test coverage. Utilized TypeScript, JavaScript, and Node.js, focusing on API development, testing, and continuous integration to streamline release cycles and maintainability.

Feb 1, 2026February 2026 highlights for Esri/arcgis-rest-js: Delivered PBF format support for feature service, enabling queries via pbf-as-geojson and pbf-as-arcgis. Implemented the necessary parsers and introduced a protobuf specification to support these formats. The feature was delivered via a merged PR that included commits to integrate PBF-based queries. Additionally, added the pbf package dependency and related package.json changes, accompanied by a changeset. This work expands data format interoperability, improves performance for large feature queries, and reduces payload size for clients leveraging PBF payloads.
