GeoStyler Style

A TypeScript declaration file and utility library defining the geostyler-style format, an exchange format for representing geographic styles that can be translated between SLD, OpenLayers, Mapbox, CartoCSS and other standards. Current stable version is 12.0.0, released April 2026. The package ships TypeScript types and includes type guards for runtime type checking. It is developed as part of GeoStyler project, which provides UI components for building styles. Key differentiator: designed as an interchange format rather than a new styling standard, capable of capturing capabilities of multiple style formats while remaining human-readable.
