Geolib is a zero-dependency JavaScript/TypeScript library providing basic 2D geospatial operations such as distance calculation (Haversine), coordinate format conversion, and GeoJSON support. It works in Node and browsers via UMD or ES module builds with tree-shakeable imports.

Use cases

• calculate distance between two gps coordinates in javascript
• convert decimal latitude longitude to sexagesimal format
• compute distance between geojson points
• find nearest coordinate to a location
• measure how far a user is from a store in meters

When to choose

• you need lightweight, zero-dependency geo math in Node or the browser
• you want tree-shakeable functions and TypeScript type definitions
• you work with decimal or sexagesimal coordinates and GeoJSON input

When to avoid

• you need 3D calculations including altitude or elevation
• you need advanced geospatial analysis like polygons, routing, or projections
• you need extremely high-precision geodesic computations (e.g. Vincenty/GeographicLib)
