## polyline-splitter

A small (<10kb minified) javascript library for splitting geojson polylines by other polylines.

### Install

````

npm install polyline-splitter

````

### API

Accepts either a geojson `Feature` or ` LineString | MultiLineString`.

Returns a `MultiLineString` containing the joined lines. 

If no intersection points are found returns the first argument.

```js

import polylineSplitter from 'polyline-splitter'

// or

const polylineSplitter = require('polyline-splitter')

const line1 = {

    "type": "LineString",

    "coordinates": [[0, 0],[10, 0]]

}

const line2 = {

    "type": "LineString",

    "coordinates": [[5, -10],[5, 10]]

}

const output = polylineSplitter(line1, line2)

// => {

//   "type":"MultiLineString",

//   "coordinates":[

//       [[0,0], [5,0]],

//       [[5,0], [10,0]],

//       [[5,-10], [5,0]],

//       [[5,0], [5,10]]

//     ]

// }

```
