Encodes/decodes into lat/lng coordinate pairs. Use fromGeoJSON() to encode from GeoJSON objects.

Installation

npm install polyline

Example

var polyline = require('polyline');
 
// returns an array of lat, lon pairs
polyline.decode('_p~iF~ps|U_ulLnnqC_mqNvxq`@');
 
// returns a string-encoded polyline
polyline.encode([[38.5, -120.2], [40.7, -120.95], [43.252, -126.453]]);
 
// returns a string-encoded polyline from a GeoJSON LineString
polyline.fromGeoJSON({ "type": "Feature",
  "geometry": {
    "type": "LineString",
    "coordinates": [[-120.2, 38.5], [-120.95, 40.7], [-126.453, 43.252]]
