Display gridded vector data (sliced GeoJSON, TopoJSON or protobuf vector tiles) in Leaflet 1.0.0


demo-geojson.html Sliced GeoJSON
demo-topojson.html Sliced TopoJSON (sorry for the antimeridian mess, topojson-to-geojson seems to not handle it properly)
demo-vectortiles.html Protobuf vector tiles: OpenMapTiles, MapBox, MapZen or even ESRI vector tiles
demo-points.html Clickable points and lines
demo-points-icons.html Points as icons


If you use npm:

    npm install leaflet.vectorgrid

That will make available two files: dist/Leaflet.VectorGrid.js and dist/Leaflet.VectorGrid.bundled.js.

The difference is that dist/Leaflet.VectorGrid.bundled.js includes all of VectorGrid's dependencies:

  • geojson-vt (Under ISC license)
  • pbf (Under BSD license)
  • topojson (Under BSD license)
  • vector-tile (Under BSD license)

    If you are adding these dependencies by yourself, use dist/Leaflet.VectorGrid.js instead.

If you don't want to deal with npm and local files, you can use unpkg.com instead:

<script src="https://unpkg.com/leaflet.vectorgrid@latest/dist/Leaflet.VectorGrid.bundled.js"></script>

or, with the same caveats about bundled dependencies:

<script src="https://unpkg.com/leaflet.vectorgrid@latest/dist/Leaflet.VectorGrid.js"></script>


This plugin exposes two new classes:

  • L.VectorGrid.Slicer for displaying GeoJSON or TopoJSON data
  • L.VectorGrid.Protobuf for displaying vector tiles from an online tile server

You can find the API documentation, and the explanation about the styling, at:



L.VectorGrid.Slicer requires geojson-vt: the global variable geojsonvt must exist. If topojson data is used, then the topojson global variable must also exist.

L.VectorGrid.Protobuf requires vector-tile and pbf: the global variables VectorTile and Pbf must exist.

By default, VectorGrid is built with those dependencies bundled.


Run npm install.


  • Sub-panes for the tile renderers (to set the "z-index" of layers/features)
    • More <g>roups in SVG
    • Offscreen <canvas>es in Canvas
  • getBounds() support for the slicer (inherit/extrapolate from geojson data)
  • Parser for mapbox-like vector stylesheets


Before VectorGrid, loading vector tiles in Leaflet could only be done with the Leaflet.MapboxVectorTile or the Hoverboard plugin, but neither of those works with Leaflet 1.0.0 (or greater).

VectorGrid leverages the GridLayer feature introduced in Leaflet 1.0.0.
