System Requirements

Supported browsers

ArcGIS Maps SDK for JavaScript 4.29 supports the following browsers:

  • Chrome 118 or later
  • Edge 118 or later
  • Firefox 121 or later
  • Firefox 115 (ESR)
  • iOS Safari 16 or later
  • Safari 16 or later

For best performance use the latest versions of the browsers listed above.

Only WebGL2-enabled, 64-bit browsers are supported.

Minimum hardware requirements

  • Desktop browsers - at least 8 GB system memory.
  • Mobile devices - at least 4 GB system memory.

Working with complex applications might require additional memory and better CPUs. GPUs and hardware acceleration are also important for basic performance of the API library, for both physical and virtualized environments.

To test for hardware acceleration, open https://webglreport.com in a browser. A Major Performance Caveat value of No indicates hardware acceleration is available. A value of Yes indicates it is not available, and the API library will automatically attempt to improve 2D map interaction and user experience by switching to a degraded rendering mode that reduces CPU utilization.

Virtualized environments

Within Virtual Desktop Infrastructure (VDI) and Remote Desktop Services (RDS) environments, each virtual desktop, machine or session must meet the minimum hardware requirements listed above per user. The following are recommendations for minimum performance:

  • At least 2 virtual CPUs (vCPUs) per user.
  • Use a physical GPU in the host server and allocate virtual GPU (vGPU) resources for each user.
  • Use the client specifically designed for your VDI or Remote Desktop Connection (RDC).
  • Run performance tests and periodically adjust the host server and client configurations for GIS workflows.

Feature-specific requirements

  • SceneView
    • Not supported on displays with a resolution above 4K

API classes and modules can have additional system requirements noted on a class by class basis in the API reference. For example, due to security considerations the Locate widget and Track widget don't work on insecure origins. The Fullscreen widget only works with browsers that implement the Fullscreen API. Thus, this feature is not supported on iOS Safari.

WebGL extensions

The API has the following features which require WebGL2 extensions that might not always be available in your browser:

To use these features with optimal visual quality, the extension EXT_color_buffer_float is required. For the HeatmapRenderer also OES_texture_float_linear is required. If any one of these extensions is not available, the HeatmapRenderer requires EXT_color_buffer_half_float instead to visualize any data in SceneView. For VoxelLayer the extension EXT_texture_norm16 is additionally required when displaying data of type INT16 or UINT16.

To test if a device supports these WebGL2 extensions, open https://webglreport.com on the device's browser and check the extensions list.

About web servers

If developing a traditional web application that is to be accessed via the browser, the recommended approach is to deploy it to a web server and access it via http:// or https:// rather than file://.

In embedded scenarios, e.g. Microsoft PowerBI, Windows Store app, or Adobe Creative Cloud, a web server is not necessary for using the ArcGIS Maps SDK for JavaScript.

Product Life Cycle

We recommend reviewing both the ArcGIS Maps SDK for JavaScript's Product Life Cycle page and the Developer Technologies section in the Esri Product Life Cycle Support Policy document. They contain detailed information on specific API version release dates and the associated product life cycle phases.
