Install and set up
The most common approach for accessing the API is to use the hosted version. Reference the API and CSS from our CDN to start using the API in your app.
<link rel="stylesheet" href="https://js.arcgis.com/4.21/esri/themes/light/main.css"> <script src="https://js.arcgis.com/4.21/"></script>
npm install @arcgis/core
Then import modules:
import Map from "@arcgis/core/Map";
For more information, see these guides:
Note: This approach is currently only recommended for development and prototyping.
<link rel="stylesheet" href="https://js.arcgis.com/4.21/@arcgis/core/assets/esri/themes/light/main.css"> <script type="module"> import Map from "https://js.arcgis.com/4.21/@arcgis/core/Map.js"; // Use the Map class </script>
In some cases, you may need to use a locally hosted version of the AMD modules via ArcGIS CDN. An example of this is when you are working in a restricted network environment with no internet access. You can also download and install the documentation which includes the API Reference, tutorials, and samples. The documentation available for download is a snapshot from the release date of version 4.21 and will not include the latest sample updates, documentation fixes, etc.
