Sep 1, 2025September 2025 monthly summary for open-formulieren/open-forms: - Delivered WMS tile layer management in the admin panel with persistence in the database, plus import/export capabilities, and exposed WMS tile layers to the map builder as background layers. This streamlines operational workflows and enables consistent map styling across admin and builder contexts. - Implemented Overlay Tile Layer support across maps and the Web Form Builder, including typing for overlays, a dedicated mapLayers module, a URL factory for overlay data, and validation checks in email digests to surface issues with WMS resources. These changes enable richer, more reliable map experiences in forms and dashboards. - Reliability and quality improvements: added safeguards to fetch overlay URLs before shipping the map component to the SDK and introduced email digest checks to surface map overlay issues early, reducing configuration errors in production. Impact: Faster onboarding for admins and form builders, reduced manual effort to configure map layers, improved data integrity and reliability for map resources, and a stronger foundation for future map-driven features. Technologies/skills demonstrated: TypeScript typing for overlays, modular mapLayers design, URL factory pattern, DB persistence and import/export, builder integration, and proactive validation in email digests.
