Build an Esri-leaflet Starter App

This lab covers the basics for creating a basic starter Esri-Leaflet mapping application. The starter map simply loads a default base map, centers and zooms it in. If you are new to Esri-Leafet you can get the examples and API documentation here.

Steps

  1. Copy and paste the code below into jsbin.com. You can also click here.

    <html>
<head>
  <meta charset=utf-8 />
  <title>Esri-Leaflet Starter App</title>
  <meta name='viewport' content='initial-scale=1,maximum-scale=1,user-scalable=no' />

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

  <!-- Load Esri Leaflet from CDN -->
  <script src="https://unpkg.com/[email protected]"></script>

  <style>
    body {margin:0;padding:0;}
    #map {position: absolute;top:0;bottom:0;right:0;left:0;}
  </style>
</head>
<body>

<div id="map"></div>

<script type='text/javascript'>
  var map = L.map('map').setView([45.533, -122.657], 12);
  L.esri.basemapLayer('DarkGray').addTo(map);
</script>

</body>
</html>

  2. Run the app and you should see a dark gray map centered on Portland, Oregon.

Bonus

  • Experiment with different basemaps such as Topographic or Gray.
  • Run the code locally on your machine. Eventually if your app gets larger you'll want to migrate it from JSBin to your desktop.
