Display a map | ArcGIS Maps SDK for JavaScript

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.

Prerequisites

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.

<html>

<head>
  <meta charset="utf-8" />
  <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no" />
  <title>ArcGIS Maps SDK for JavaScript Tutorials: Display a map</title>

</head>


<body>

</body>


</html>

Add CSS

In CodePen > HTML, add CSS to set the map to use the full width and height of the browser.

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 the apiKey property on the global esriConfig variable to your access token.

<!-- The esriConfig variable must be defined before adding the other esri libraries -->
<script>

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

</script>

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

Add the ArcGIS Maps SDK for JavaScript script tag

In the <head>, add the <script> tag for the JavaScript Maps SDK.

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.
