Add a vector tile layer

Learn how to add a vector tile layer to a map.

Add a vector tile layer using API key authentication

A vector tile layer is a hosted data layer with vector tile data. You can create a vector tile layer by publishing your data with data management tools.

In this tutorial, you display a parcels layer from a public vector tile service with its default styling.

Prerequisites

An ArcGIS Location Platform or ArcGIS Online account.

Steps

Get the starter app

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

You can choose one of the following to create a new CodePen:

Option 1: Complete the Display a map tutorial; or,
Option 2: Start from the Display a map tutorial .

Set up authentication

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

Create a new API key credential with 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
- Item access
  - Note: If you are using your own custom data layer for this tutorial, you need to grant the API key credentials access to the layer item. Learn more in Item access privileges.
When prompted, copy and paste the API key to a safe location. It will be used in the next step.

Set developer credentials

Use the API key or OAuth developer credentials so your application can access location services.

Update the accessToken variable to use your API key.

Use dark colors for code blocks
  <script>

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

    const map = L.map("map", {
      minZoom: 2
    })

    map.setView([34.02, -118.805], 13);

    const basemapEnum = "arcgis/streets";

    L.esri.Vector.vectorBasemapLayer(basemapEnum, {
      token: accessToken
    }).addTo(map);

  </script>

In both the index.html and callback.html files, replace YOUR_CLIENT_ID and YOUR_REDIRECT_URL with the client ID and redirect URL of your OAuth credentials.

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

callback.html
Use dark colors for code blocks
    arcgisRest.ArcGISIdentityManager.completeOAuth2({
      clientId: "YOUR_CLIENT_ID", // Your client ID from OAuth credentials
      redirectUri: "YOUR_REDIRECT_URL", // 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 a vector tile layer

To access the vector tile service, you use the vectorTileLayer class.

Create a vectorTileLayer and set the url of the layer before adding it to the map.
