MapLibre GL Leaflet

This is a binding from MapLibre GL JS to the familiar Leaflet API. It was originally developed for Mapbox (https://github.com/mapbox/mapbox-gl-leaflet) and was migrated to MapLibre after Mapbox changed its license.

Code example

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.maplibreGL({
  style: "mapbox://styles/mapbox/bright-v8",
}).addTo(map);

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

var gl = L.maplibreGL({
  style:
    "https://api.maptiler.com/maps/topo/style.json?key=<YOUR_MAPTILER_API_KEY>",
}).addTo(map);

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

gl.getMaplibreMap()....
// add a source to the maplibre-gl layer
gl.getMaplibreMap().addSource({...})

Installation

Add a script tag referencing maplibre-gl-leaflet after adding leaflet and maplibre-gl-js in your website:

<!-- Leaflet -->
<link
  rel="stylesheet"
  href="https://unpkg.com/[email protected]/dist/leaflet.css"
/>
<script src="https://unpkg.com/[email protected]/dist/leaflet.js"></script>

<!-- Maplibre GL -->
<link
  href="https://unpkg.com/[email protected]/dist/maplibre-gl.css"
  rel="stylesheet"
/>
<script src="https://unpkg.com/[email protected]/dist/maplibre-gl.js"></script>

<script src="https://unpkg.com/@maplibre/[email protected]/leaflet-maplibre-gl.js"></script>

Motivation

This project makes it possible to easily add a maplibre-gl-js layer in your Leaflet map. When using maplibre-gl-leaflet, you won't be able to use some of the maplibre-gl-js features. Here are the main differences between a "pure" maplibre-gl-js map and a Leaflet map using maplibre-gl-leaflet:

• No rotation / bearing / pitch support
• Slower performances: When using maplibre-gl-leaflet, maplibre-gl-js is set as not interactive. Leaflet receives the touch/mouse events and updates the maplibre-gl-js map behind the scenes. Because maplibre-gl-js doesn't redraw as fast as Leaflet, the map can seem slower.

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

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