# gtran-shapefile

[![NPM Version](https://img.shields.io/npm/v/gtran-shapefile.svg)](https://www.npmjs.com/package/gtran-shapefile) [![Build Status](https://travis-ci.org/haoliangyu/gtran-shapefile.svg?branch=master)](https://travis-ci.org/haoliangyu/gtran-shapefile)

convert geojson to shapefile and backwards

## Installation

```javascript

npm install gtran-shapefile

```

## Functions

* **setPromiseLib(object)**

    Specify the promise library. If not, the library will use the native Promise.

* **fromGeoJson(geojson, fileName, options)**

    Save the geojson into the given file name.

    Options:

    * **esriWKT**: ESRI WTK string that specifies the shapefile's spatial reference and generates .prj file. It could be found at [SpatialReference.org](http://spatialreference.org/).

* **toGeoJson(fileName)**

    Read the given file and convert it into geojson.

## Use Example

```javascript

var shp = require('gtran-shapefile');

// if specific promise library is needed

shp.setPromiseLib(require('bluebird'));

// Read shapefile

shp.toGeoJson('source.shp')

.then(function(object) {

    var geojson = object;

});

// Save geojson into shapefile

shp.fromGeoJson(geojson, 'point.shp', {

  // ESRI WKT string of WGS84

  esriWKT: 'GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137,298.257223563]],PRIMEM["Greenwich",0],UNIT["Degree",0.017453292519943295]]'

})

.then(function(fileNames) {

    console.log('files have been saved at:' + fileNames);

});

```
