Display a map | ArcGIS Maps SDK for JavaScript

Learn how to create and display a map A map is a collection of layers that are displayed in 2D. It is typically composed of a basemap layer and data layers. Learn more with a basemap layer A basemap layer is the layer in a map or scene that displays basemap data. The data source for a basemap layer is typically a basemap service. Learn more .

A map contains layers A layer is a reference to a collection of geographic data that is used to access and display data. The data for layers are typically provided by the basemap layer service and data services. Learn more of geographic data. Maps include a basemap layer A basemap layer is the layer in a map or scene that displays basemap data. The data source for a basemap layer is typically a basemap service. Learn more and, optionally, one or more data layers A data layer is a layer that references geographic data from a file or a service and is used to visualize the data in a map or scene. Learn more . You can display a specific area of a map by setting the location A location is a position or region (point, line, or polygon) on the earth's surface. Learn more and zoom level Zoom level is a value that sets the scale for a map view or a scene view. Learn more .

This tutorial shows you how to create and display a map A map is a collection of layers that are displayed in 2D. It is typically composed of a basemap layer and data layers. Learn more of the Santa Monica Mountains in California using the topographic basemap layer A basemap layer is the layer in a map or scene that displays basemap data. The data source for a basemap layer is typically a basemap service. Learn more .

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 An access token is an authorization string that provides access to secure ArcGIS content, data, and services. Its capabilities are determined by the privileges it supports. It is obtained by implementing API key authentication, User authentication, or App authentication. Learn more with the correct privileges to access the location services ArcGIS Location Services, also referred to as Location Services, are services hosted by Esri that provide geospatial functionality for developing mapping applications. They include the ArcGIS Basemap Styles service, ArcGIS Static Basemap Tiles service, ArcGIS Places service, ArcGIS Geocoding service, ArcGIS Routing service, ArcGIS GeoEnrichment service, and ArcGIS Elevation service. An ArcGIS Location Platform or ArcGIS Online account is required to use the services. Learn more used in this tutorial.

Go to the Create an API key tutorial and create an API key An API key is a long-lived access token created using API key credentials. They are valid for up to one year and are typically embedded directly into client applications. Learn more with the following privilege(s) Privileges are a set of permissions assigned to ArcGIS accounts, developer credentials, and applications that grant access to secure resources and functionality in ArcGIS. Learn more :
- 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 A basemap layer is the layer in a map or scene that displays basemap data. The data source for a basemap layer is typically a basemap service. Learn more layer, location A location is a position or region (point, line, or polygon) on the earth's surface. Learn more and zoom level Zoom level is a value that sets the scale for a map view or a scene view. Learn more .

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

Run the app

In CodePen, run your code to display the map.

The map should display the topographic basemap layer A basemap layer is the layer in a map or scene that displays basemap data. The data source for a basemap layer is typically a basemap service. Learn more for an area of the Santa Monica Mountains in California.
