During September 2025, Chris Sexton refactored map state management in the WFP-VAM/prism-app repository by introducing a custom useMapState hook. This new approach centralized map-related state, including layers, date ranges, and the map instance, within a dedicated React hook, reducing reliance on Redux for these concerns. By isolating map state logic, Chris improved the maintainability of the codebase and set the stage for faster delivery of future map features. The work leveraged JavaScript, TypeScript, and React, demonstrating a thoughtful application of state management principles to streamline feature development and enhance the project’s overall architecture.
