## Display Map
2015-12-15 11:29:28 +00:00
To display a custom MapboxGL based map you need to create a HTML file and
reference the public vector tile server of osm2vectortiles. You are free to download and
host the vector tiles yourself but we provide a fast and distributed CDN service for serving
the PBFs for you.

2015-12-15 11:29:28 +00:00
The easiest way to get started is using the `mapbox-gl-js-exmaple` repository.
2015-12-15 11:19:26 +00:00
Clone the repository and change into the directory.
```
git clone https://github.com/osm2vectortiles/mapbox-gl-js-example.git
```

## Configure Source, Fonts and Sprites
2015-12-15 11:19:26 +00:00
In order for Mapbox GL JS to work you also need to provide the
[fonts ](https://www.mapbox.com/mapbox-gl-style-spec/#glyphs ) and
[sprites ](https://www.mapbox.com/mapbox-gl-style-spec/#sprite ).
These resources are contained in the folder `assets` .
The [Mapbox GL Style JSON ](https://www.mapbox.com/mapbox-gl-style-spec/ ) of OSM Bright is located at `bright-v8.json` .
You can create your own styles with Mapbox Studio.
If you want to serve the Mapbox GL Style JSON without Mapbox you need to configure three URLs.
1. Change the `sources` URL to the free osm2vectortile serve or use your own server
2. Change the `sprite` URL to the location of your sprites
3. Change the `glyphs` URL to the location of your fonts
```javascript
"sources": {
"mapbox": {
"url": "http://vectortiles.osm2vectortiles.org/world.json",
"type": "vector"
}
},
"sprite": "/assets/sprite",
"glyphs": "/assets/font/{fontstack}/{range}.pbf"
```

## Initialize the Map
2015-12-15 10:19:32 +00:00
2015-12-15 11:29:28 +00:00
In order to serve a MapboxGL based map you need a [Mapbox GL style JSON ](https://www.mapbox.com/mapbox-gl-style-spec/ ) created with [Mapbox Studio ](https://www.mapbox.com/mapbox-studio/ ).
2015-12-15 10:19:32 +00:00
In this example we will serve the free OSM Bright style [provided by Mapbox ](https://github.com/mapbox/mapbox-gl-styles ).
2015-12-15 11:29:28 +00:00
The HTML file defines a full screen map and the CSS and JavaScript files required by Mapbox GL JS.
The `bright-v8.json` style is loaded from the local directory.
2015-12-15 10:19:32 +00:00
2015-12-15 11:19:26 +00:00
Because we use the local sprites and fonts we don't need a Mapbox API key.

## Serve the Map
You need a simple HTTP server for serving the HTML and assets.
If you have Python installed you can run `python -m SimpleHTTPServer`
in the working directory and visit the map at `localhost:8000` .
If you have NodeJS installed you can install a simple http server with `npm install http-server -g`
and run it in the working directory with `http-server` and visit the map at `localhost:8080` .
Or if you are using Docker you can run a container serving the static files at `localhost:8000`
with `docker run --rm -v $(pwd):/usr/share/nginx/html:ro -p 8000:80 nginx` .
It is even possible to host the map on GitHub Pages.
