geographiclib-geodesic

JavaScript implementation of the geodesic routines from GeographicLib for solving direct and inverse geodesic problems on an ellipsoid of revolution. Current stable version is 2.2.0, released on 2025-01-01 with monthly releases. Key differentiators: high accuracy (nanometer precision), pure JavaScript with no native dependencies, TypeScript types included, supports both ESM and CJS. Used for distance, azimuth, and destination calculations on the WGS84 ellipsoid and other reference ellipsoids. Split from monolithic geographiclib package in v2.0.0 into this and geographiclib-dms.
