A LeafletJS plugin to load tilesets in .mbtiles format.


The following demo loads a ~9.6MB .mbtiles file with the "countries" style from the good ol' Tilemill:



LeafletJS 1.0.1 (or newer), sql.js 0.3.2 (or newer), and a web browser that supports:

Any recent version of Firefox, Chrome or Safari should work without problems. IE10/IE11 should work with a fetch polyfill.


Include Leaflet in your HTML, like:

<link rel="stylesheet" href="https://unpkg.com/leaflet@1.0.1/dist/leaflet.css" />
<script src="https://unpkg.com/leaflet@1.0.1/dist/leaflet.js"></script>

Include the sql.js library, like:

<script src="https://unpkg.com/sql.js@0.3.2/js/sql.js"></script>

Include Leaflet.TileLayer.MBTiles, like:

<script src="https://unpkg.com/leaflet.tilelayer.mbtiles@latest/Leaflet.TileLayer.MBTiles.js"></script>

Once everything is loaded, you can instantiate L.TileLayer.MBTiles just by providing the URL to a .mbtiles database:

var mb = L.tileLayer.mbTiles('http://server/something/cool-stuff.mbtiles').addTo(map);

Extra metadata handling

Some .mbtiles have metadata rows which is not in the specification .mbtiles format. This plugin will handle the following optional metadata rows, if they exist:

  • minzoom (as the layer's minzoom option).
  • maxzoom (as the layer's maxzoom option).
  • attribution (as the layer's attribution option).

Due to the database being opened asynchronously, and the fact that layer options have to be given when the layer is instantiated, metadata handling does not work very well. Consider handling the metadata manually and setting Leaflet layer options accordingly.
