Display a map | Overview | ArcGIS Maps SDK for JavaScript 4.33

Learn how to create and display a map with a basemap layer.

A map contains layers of geographic data. Maps include a basemap layer and, optionally, one or more data layers. You can display a specific area of a map by setting the location and zoom level.

This tutorial shows you how to create and display a map of the Santa Monica Mountains in California using the topographic basemap layer.

The map and code in this tutorial will be used as the starting point for other 2D tutorials.

Note

For more information about maps and layers, visit Maps, scenes, and layers in the Mapping and location services guide.

Prerequisites ArcGIS Accounts:

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.

The <!doctype html></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 both the opening and closing tag.

Add basic HTML

Define a basic HTML page.

In CodePen > HTML, add HTML to create a basic page.

Get an access token

You need an access token with the correct privileges to access the location services 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

In CodePen, set esriConfig.apiKey to your access token.

  var esriConfig = {
    apiKey: "YOUR_ACCESS_TOKEN",
  };

</script>

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

Add references

In the <head>, add the <script> and <link> tags for the Map Components and the Calcite Design System.

Add a map

Use the Map component to set the basemap layer, location and zoom level.

In the <body> tag, add the <arcgis-map> component and specify the basemap, center and zoom attributes.

    </arcgis-map>

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.
