A [TileStrata](https://github.com/naturalatlas/tilestrata) plugin for generating [mapnik](http://mapnik.org/) vector tiles (pbf). Vector tiles are useful for times when you want to render multiple variations of a tile (1x, 2x, interactivity, etc) without having to do expensive data fetching for each. Use the [tilestrata-vtile-raster](https://github.com/naturalatlas/tilestrata-vtile-raster) plugin to render them into normal images. To use this plugin, you must have [node-mapnik](https://github.com/mapnik/node-mapnik) in your dependency tree.

### Sample Usage

```js
var vtile = require('tilestrata-vtile');
var vtileraster = require('tilestrata-vtile-raster');

var common = {
    xml: '/path/to/map.xml',
    tileSize: 256,
    metatile: 1,
    bufferSize: 128
};

server.layer('mylayer')
    .route('t.pbf').use(vtile(common))
    .route('t.png').use(vtileraster(common, {
        tilesource: ['mylayer', 't.pbf']
    }))
    .route('i.json').use(vtileraster(common, {
        tilesource: ['mylayer', 't.pbf'],
        interactivity: true
    }));
```

If you need fine control over the Mapnik vector tile creation options, use the `overrideRenderOptions` option:

```js
server.layer('mylayer')
    .route('t.pbf').use(vtile({
        xml: '/path/to/map.xml',
        tileSize: 256,
        metatile: 1,
        bufferSize: 128,
        overrideRenderOptions: function(opts, z, maxz) {
            opts.simplify_distance = z < maxz ? 8 : 1;
            return opts;
        }
    }))
```
