ArcGIS REST JS
ArcGIS REST JS is a light-weight collection of JavaScript modules for accessing ArcGIS services and building mapping and spatial analysis applications. The library makes it easy to perform authentication with API keys and OAuth 2.0 and to make requests to ArcGIS location services and ArcGIS Enterprise services. For example, you can make requests to perform data queries, geocoding, routing, demographic queries, content management, and administration tasks. The library is available as ES, CommonJS, and UMD modules for client and server-side use.
