Display a map

Learn how to display a map with a basemap layer using MapLibre GL JS.

You can display a map in MapLibre GL JS by using a vector tile basemap layer from the basemap styles service. A vector tile basemap layer is a MapLibre GL style containing a source, 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 tutorial is the starting point for the other MapLibre 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 mapping 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.

The HTML will create a page with a map that is the full width and height. The map div is the element used to display the map. The CSS resets any browser settings so the map can consume the full width and height of the browser.

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 your div with the basemap you specify.

The Map class uses the map HTML element to display the contents of the map and to provide a user interface to interact with. It supports clicking, zooming, panning, rotating, and tilting the perspective of the map. It also allows you to interact with and discover information about the map data such as finding features where the mouse is clicked. You can also use it to modify the data displayed, by adding new sources or changing layer properties.

For more information, see the MapLibre GL JS documentation.

Add a <script>...</script> section at the end of the <body>...</body> section.

Create an accessToken variable to store your API key. Replace YOUR_ACCESS_TOKEN with the access token you previously copied. You will need to include this in the URL of each ArcGIS service you are accessing. You do not need to set mapboxgl.accessToken. Create a basemapEnum variable to store the basemap identifier, arcgis/streets.

Create a Map with options to control its display and behavior. Set the container property to the map id of the div you created. The style property references the location of the basemap styles service and contains the basemap identifier and your API key.

        center: [-118.805, 34.027] // starting location [longitude, latitude]
      });

Run the app

In CodePen, run your code to display the map.

The map should display the topographic basemap layer for an area of the Santa Monica Mountains in California.
