WKT/WKB/GeoJSON Parser and Serializer

wkx is a robust JavaScript library designed for comprehensive parsing and serialization of spatial data in various formats. It supports the Open Geospatial Consortium (OGC) well-known text (WKT), well-known binary (WKB), extended well-known text (EWKT), extended well-known binary (EWKB), and tiny well-known binary (TWKB) standards, alongside GeoJSON. The library handles all fundamental OGC geometry types, including Point, LineString, Polygon, MultiPoint, MultiLineString, MultiPolygon, and GeometryCollection, providing a unified API for interacting with these diverse spatial representations. The current stable version is 0.5.0, with the last publish being six years ago as of April 2026. While specific release cadence is not detailed, the presence of build status badges suggests active maintenance. A key differentiator of wkx is its ability to seamlessly convert between these numerous formats, offering flexibility for developers working with disparate geospatial data sources and output requirements, from database storage to web mapping applications.
