Learn how to change the basemap layer in a map .
The basemap layer service provides a number of basemap layer styles such as topography, streets, and imagery that you can use in maps.
In this tutorial, you use the Basemap Toggle and BasemapGallery widgets to select and display different basemap layers .
PrerequisitesYou need a free ArcGIS developer account to access your dashboard and API keys . The API key must be scoped to access the services used in this tutorial.
Steps Create a new penTo get started, either complete the Display a map tutorial or use this pen . Set the API keyTo access ArcGIS services , you need an API key .
Go to your dashboard to get an API key .
In CodePen , set the apiKey
to your key, so it can be used to access basemap layer and location services.
Change line
esriConfig.apiKey = "YOUR-API-KEY" ;
const map = new Map ({
basemap : "arcgis-topographic" //Basemap layer service
});
Add modulesIn the require
statement, add the Basemap Toggle and BasemapGallery modules.
More info The ArcGIS API for JavaScript uses AMD modules . The require
function is used to load modules so they can be used in the main function
. It's important to keep the module references and function parameters in the same order.

Toggle between basemapsAn easy way to enable selection between two basemaps is to use the Basemap Toggle widget. Use the widget to toggle between arcgis-topographic
and arcgis-imagery
basemaps.
Create a Basemap Toggle and set the view
. Set the nextBasemap
property to arcgis-imagery
.

Switch between basemaps.
Select basemaps from a galleryYou can also use the BasemapGallery widget to select different basemaps.
Create a BasemapGallery and set the query
in the source
property to search for the "World Basemaps for Developers" basemap group.
More info In a future release, you will not need to set the source
when using API keys.

Run the AppIn CodePen , run your code to display the map.
You should have two widgets in your application that provide different ways to choose basemaps.
