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 .
Prerequisites You 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 pen To get started, either complete the Display a map tutorial or use this pen . Set the API key To 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.

esriConfig.apiKey = "YOUR_API_KEY" ;
const map = new Map ({
basemap : "arcgis-topographic" // Basemap layer service
});
Add modules In 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 basemaps An 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 viewnextBasemaparcgis-imagery.

Switch between basemaps.
Select basemaps from a gallery You can also use the BasemapGallery widget to select different basemaps.
Create a BasemapGallery and set the query in the source
More info In a future release, you will not need to set the source when using API keys.
