Learn how to search for businesses, POIs, and geographic locations with the geocoding service .
Place finding is the process of searching for a place name or POI to find its address and location . You can use the Geocoding service to find places such as coffee shops, gas stations, or restaurants for any geographic location around the world. You can search for places by name or by using categories. You can search near a location or you can search globally.
In this tutorial, you use a locatorGeocoding service and find places by place category. Pop-ups are used to display the place name and address.
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 api 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 locatorGraphic
More info The ArcGIS Maps SDK for JavaScript is available as AMD modules and ES modules , but this tutorial is based on AMD. The AMD require function uses references to determine which modules will be loaded – for example, you can specify "esri/Map" for loading the Map module. After the modules are loaded, they are passed as parameters (e.g. Map) to the callback function where they can be used in your application. It is important to keep the module references and callback parameters in the same order. For more information on the different types of modules, visit the Introduction to Tooling guide topic.
