System Requirements

Supported browsers

ArcGIS Maps SDK for JavaScript 4.28 supports the following browsers:

• Chrome 115 or later
• Edge 115 or later
• Firefox 117 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 WebGL-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.

GPUs are important for basic performance. Working with complex applications might require additional memory and better CPUs.

Virtual Desktop Infrastructure (VDI) - within a VDI environment, each virtual desktop or virtual machine must meet the minimum hardware requirements listed above per user. The following are recommendations for minimum performance:

• 2 virtual CPUs (vCPUs) per virtual desktop.
• Use a physical GPU in the host server and allocate virtual GPU (vGPU) resources for each virtual desktop.
• Use the client specifically designed for your VDI.
• Test and periodically adjust the VDI configuration for GIS workflows.

When no hardware acceleration is detected, the API library automatically attempts to improve map interaction and user experience for some virtual desktop and Remote Desktop Host environments by switching to a degraded 2D rendering mode.

Feature-specific requirements

• SceneView
  • Not supported on displays with a resolution above 4K
  • Requires WebGL2

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:

• SceneView
  • SceneView.qualityProfile with settings "high" or "medium" to support high quality transparency
  • VoxelLayer
  • ImageryTileLayer
  • HeatmapRenderer

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://.

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.
