This repo contains the code that accompanies the Build a WebGL Vector Map tutorial.

It's pirmarily used as an exercise in learning WebGL and rendering Vector Tiles. Any comments or suggestions are more than welcome 😄

To use, a map can be instantiated with the id of the div to render to.

const map = new WebGLMap({
  id: 'myCanvasId',
  tileServerURL: 'https://maps.ckochis.com/data/v3/{z}/{x}/{y}.pbf',
  width: 800,
  height: 600,
  center: [-73.9834558, 40.6932723]
  minZoom: 4,
  maxZoom: 18,
  zoom: 13,
  debug: true,
  layers: {
    water: [180, 240, 250, 255],
    landcover: [202, 246, 193, 255],
    park: [202, 255, 193, 255],
    building: [185, 175, 139, 191],
  }
});

The other requrement is a URL to a tile server that uses the Mapbox Vector Tile Specification.

// example
"https://maps.ckochis.com/data/v3/{z}/{x}/{y}.pbf"

You will also need to specify the layers to render, along with an RBG value. The demo is using the OpenMapTiles scehma.
