### Handling other coordinate reference systems

This library does not directly support reprojection. If you require the output GeoJSON in WGS84, you can use the `reproject` library as follows.

If there is a `.prj` file present:

```
const shapefile = require('shapefile');
const reproject = require('reproject');
shapefile.read(basename + '.shp').then(result => {
const prj = fs.readFileSync(basename + '.prj', 'utf-8');
const projected = reproject.toWgs84(result, prj);
});
```

If you know the EPSG code for the source projection:

```
const shapefile = require('shapefile');
const reproject = require('reproject');
const epsg = require('epsg');
shapefile.read(basename + '.shp').then(result => {
const projected = reproject.toWgs84(result, 'EPSG:3857', epsg);
});
```
