* Add `.fromGeoJSON` method to encode GeoJSON geometries as polylines
  without needing to manually flip coordinates.

0.1.0 (2015-06-21)

[![Build Status](https://secure.travis-ci.org/mapbox/polyline.png?branch=master)](http://travis-ci.org/mapbox/polyline) [![Coverage Status](https://coveralls.io/repos/mapbox/polyline/badge.svg)](https://coveralls.io/r/mapbox/polyline)

# polyline

A simple [google-esque polyline](https://developers.google.com/maps/documentation/utilities/polylinealgorithm)
implementation in Javascript. Compatible with nodejs (`npm install polyline` and the browser (copy `src/polyline.js`)).

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

## Installation

    npm install polyline

## Example

```js
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": example_flipped
  },
  "properties": {}
});
```
