Parlt developed and released the ArcGIS Basemap Sessions package for the Esri/arcgis-rest-js repository, creating a reusable solution for managing basemap style service sessions with robust token lifecycle handling. Over two months, Parlt refactored core logic into modular components, improved maintainability by removing deprecated assets, and introduced a MapLibre GL JS-based usage demo. The work included implementing duration-based session control, centralized defaults, and auto-refresh mechanics, as well as modernizing CI/CD workflows and upgrading the testing framework to Vitest. Using TypeScript and JavaScript, Parlt enhanced reliability, streamlined integration, and established a foundation for future extensibility and maintainable code practices.

June 2025: Delivered the ArcGIS Basemap Sessions package for Esri/arcgis-rest-js, establishing a reusable mechanism to initiate, maintain, and refresh basemap style service sessions with robust token handling. Implemented a core refactor to improve maintainability by splitting logic into focused modules and removing deprecated assets. Added an initial docs package and a MapLibre GL JS-based usage demo to accelerate adoption. These changes reduce integration effort for customers, improve runtime reliability through explicit session lifecycle management, and lay groundwork for future enhancements.
