Display a map

Learn how to use Esri Leaflet and the basemap styles service to display a map.

You can display a map with Esri Leaflet by using a vector tile basemap layer from the basemap styles service. A vector tile basemap layer contains the styles, layers, font glyphs, and icons to render the layers.

In this tutorial, you display a map of the Santa Monica Mountains using the streets basemap layer from the Basemap styles service.

This code is used as the starting point for the other Esri Leaflet tutorials.

Prerequisites

You need an ArcGIS Location Platform or ArcGIS Online account.

Steps

Create a new pen

Go to CodePen to create a new pen for your application.

Add HTML

Define an HTML page to create a map that is the full width and height of the browser window.

In CodePen > HTML, add HTML and CSS to create a page with a div element called map.

Use the HTML to create a page with a map. Use the map div to display the map. Use the CSS to make the map full width and height.

The <!DOCTYPE html> tag is not required in CodePen. If you are using a different editor or running the page on a local server, be sure to add this tag to the top of your HTML page.

Use dark colors for code blocks
<!DOCTYPE html>
<html>

  <head>
    <meta charset="utf-8" />
    <meta name="viewport" content="initial-scale=1,maximum-scale=1,user-scalable=no" />

    <style>
      body {
        margin: 0;
        padding: 0;
      }
      #map {
        position: absolute;
        top: 0;
        bottom: 0;
        right: 0;
        left: 0;
        font-family: Arial, Helvetica, sans-serif;
        font-size: 14px;
        color: #323232;
      }
    </style>
  </head>

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

  </body>

</html>

Add script references

To access vector basemap layers, you reference both the esri-leaflet and the esri-leaflet-vector plugins in addition to theleaflet libraries.

Add <script> and <link> tags to reference the libraries.

Get an access token

You need an access token with the correct privileges to access the resources used in this tutorial.

Go to the Create an API key tutorial and create an API key with the following privilege(s):
- Privileges
  - Location services > Basemaps
Copy the API key access token as it will be used in the next step.

To learn about other ways to get an access token, go to Types of authentication.

Create a map

Use a map to add a map to the div element with the basemap you specify. To find the list of default basemap styles, go to Basemap styles service.

Add <script> elements in the HTML <body>. Create a map with the minZoom set to 2.

Call the setView method to center the map on the coordinates 34.02, -118.805 and to set the zoom level to 13.

Create an accessToken variable to store your access token. Replace YOUR_ACCESS_TOKEN with the access token you previously copied from your API key credentials.

Instantiate the vectorBasemapLayer class and set the basemapEnum and accessToken before adding the layer to the map.

        token: accessToken
      }).addTo(map);

Run the app

In CodePen, run your code to display the map. The map should display a street basemap layer centered on Point Dume in California.
