Display a map

Learn how to use the ArcGIS Basemap Styles service to display a vector tile basemap.

Display a map using API key authentication

The ArcGIS Basemap Styles service provides a number of basemap styles such as topography, streets, outdoor, navigation, and imagery that you can use in maps. To display a basemap style from the service in a MapLibre GL JS app, use the MapLibre ArcGIS plugin.

In this tutorial, display a map of the world with the arcgis/outdoor basemap style.

This application will use the basemap tiles usage model .

Prerequisites

You need an ArcGIS Location Platform or ArcGIS Online account.

Steps

Create a new app

Select a type of authentication below and follow the steps to create a new application.

Create a new CodePen app with a map div that is the full width and height of the browser window.

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

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" />
  <title>MapLibre GL JS Tutorials: Display a map</title>
  <style>
    html,
    body,
    #map {
      padding: 0;
      margin: 0;
      height: 100%;
      width: 100%;
      font-family: Arial, Helvetica, sans-serif;
      font-size: 14px;
      color: #323232;
    }

  </style>

</head>


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

</body>


</html>

Create a new app by downloading the user authentication starter app and add a map div that is the full width and height of the browser window.

Download the user authentication starter app.
Unzip the folder and open it in a text editor of your choice, such as Visual Studio Code. The starter app includes the following:
- callback.html: This contains callback as part of the authentication process.
- index.html: This contains app logic and the OAuth 2.0 code necessary to perform the authentication.

In the index.html, add a div element called map.

Use dark colors for code blocks
  <body>

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

Apply CSS styling to the map div.

      body,

      #map {
        padding: 0;
        margin: 0;
        height: 100%;
        width: 100%;
        font-family: Arial, Helvetica, sans-serif;
        font-size: 14px;
        color: #323232;
      }

Set up authentication

Create developer credentials in your portal for the type of authentication you selected.

Create a new API key credential with the correct privileges to access the resources used in this tutorial.

Go to the Create an API key tutorial to follow the steps to get an access token with these privilege(s):
- Privileges
  - Location services > Basemaps

Set developer credentials

Use the API key or OAuth developer credentials created in the previous step in your application.

Add a <script> element in the HTML <body> and create an accessToken variable to store your access token. Set YOUR_ACCESS_TOKEN with the access token you previously copied from your API key credentials.

  <script>

    /* Use for API key authentication */
    const accessToken = "YOUR_ACCESS_TOKEN";

  </script>

In both the index.html and callback.html files, set the properties of clientId and redirectUri with the client ID and redirect URL of your OAuth credentials.

index.html
Use dark colors for code blocks
    /* Use for user authentication */
    const clientId = "YOUR_CLIENT_ID"; // Your client ID from OAuth credentials
    const redirectUri = "YOUR_REDIRECT_URI"; // The redirect URL registered in your OAuth credentials
    const session = await arcgisRest.ArcGISIdentityManager.beginOAuth2({
        clientId,
        redirectUri,
        portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    });

    const accessToken = session.token;

callback.html
Use dark colors for code blocks
    arcgisRest.ArcGISIdentityManager.completeOAuth2({
      clientId: "YOUR_CLIENT_ID", // Your client ID from OAuth credentials
      redirectUri: "YOUR_REDIRECT_URI", // The redirect URL registered in your OAuth credentials
      portal: "https://www.arcgis.com/sharing/rest" // Your portal URL
    });

Run the app and ensure you can sign in successfully.

If you are unable to sign in, make sure you have the correct redirect URL and port. This URL varies based on your application and typically takes the format of https://<server>[:port]/callback.html or http://my-arcgis-app:/auth. For example, if you are running an application on http://127.0.0.1:5500/, set http://127.0.0.1:5500/callback.html as your redirect URL in the index.html and callback.html file and your developer credential. They all have to match!

Add script references

Reference the MapLibre GL JS library and the MapLibre ArcGIS plugin.

In the index.html file, add the following <link> and <script> references.

  <meta charset="utf-8" />

Create a map

Create a map to display an ArcGIS basemap style centered on the world. Use the MapLibre ArcGIS plugin to access the basemap style.

Use the plugin to apply a BasemapStyle to the map. The plugin will automatically apply Esri and data attribution.
