In rstudio/leaflet.mapboxgl: Mapbox GL JS plugin for Leaflet to support vector tiles

Note: this tool is experimental and is not actively supported by Mapbox. For support, please open an issue in this repository.

Mapbox GL Leaflet

This is a binding from Mapbox GL JS to the familiar Leaflet API.

Code example

var token ="pk.XXXX"; // replace with your Mapbox API Access token. Create a Mabpox account and find it on https://www.mapbox.com/studio/

var map = L.map('map').setView([38.912753, -77.032194], 15);
L.marker([38.912753, -77.032194])
    .bindPopup("Hello <b>Leaflet GL</b>!<br>Whoa, it works!")
    .addTo(map)
    .openPopup();
var gl = L.mapboxGL({
    accessToken: token,
    style: 'mapbox://styles/mapbox/bright-v8'
}).addTo(map);

Note that you can use any vector tile source useable by mapbox-gl. For instance, you can use OSM2VectorTiles with:

var gl = L.mapboxGL({
    style: 'https://raw.githubusercontent.com/osm2vectortiles/mapbox-gl-styles/master/styles/bright-v9-cdn.json',
    accessToken: 'no-token'
}).addTo(map);

Once you have created the leaflet layer, the mapbox-gl map object can be accessed using

gl._glMap...
// add a source to the mapbox-gl layer
gl._glMap.addSource({...})

Get your Mapbox token

Create a mapbox account, then head to https://www.mapbox.com/studio/ and copy your access token that was automatically created for you. The access token should start with "pk.".

Installation

Add a script tag referencing mapbox-gl-leaflet after adding leaflet in your website:

<link rel="stylesheet" href="leaflet.css" />
<script src="leaflet.js"></script>
<script src="leaflet-mapbox-gl.js"></script>

<!-- Mapbox GL -->
<link href='https://api.tiles.mapbox.com/mapbox-gl-js/v0.14.3/mapbox-gl.css' rel='stylesheet' />
<script src='https://api.tiles.mapbox.com/mapbox-gl-js/v0.14.3/mapbox-gl.js'></script>

You can also use Unpkg as a CDN using:

<script src="https://unpkg.com/mapbox-gl-leaflet@0.0.3/leaflet-mapbox-gl.js"></script>

Motivation

This project makes it possible to easily add a mapbox-gl-js layer in your Leaflet map. When using mapbox-gl-leaflet, you won't be able to use some of the mapbox-gl-js features. Here are the main differences between a "pure" mapbox-gl-js map and a Leaflet map using mapbox-gl-leaflet: - No rotation / bearing / pitch support - Slower performances: When using mapbox-gl-leaflet, mapbox-gl-js is set as not interactive. Leaflet receives the touch/mouse events and updates the mapbox-gl-js map behind the scenes. Because mapbox-gl-js doesn't redraw as fast as Leaflet, the map can seem slower.

On the bright side, the mapbox-gl-leaflet binding will allow you to use all the leaflet features and plugins.

If you only need the mapbox-gl-js features (adding a map with a mapbox-style, adding a GeoJSON, etc.), you are probably better off using it directly.
