ArcGIS API for JavaScript versions 4.5 and 3.22 released
The ArcGIS API for JavaScript helps you create web mapping apps that use the geospatial capabilities provided by the ArcGIS platform. For example, you can create apps that display maps in 2D and 3D, integrate with ready-to-use content and services, and more, all in modern browsers like Chrome, Edge, Firefox, Internet Explorer (11 or higher), and Safari (7.1 or higher).
The API supports HTML5 and CSS3 components, so you can develop apps that take advantage of modern browser capabilities to improve performance and flexibility. You can also use developer-friendly widgets, flexible UI placement tools, and pop-up windows to build apps that are responsive to any screen size.
The new Version 4.5 of the ArcGIS API for JavaScript adds some key capabilities and several smaller enhancements, e.g.:
- Fast feature layers: Interact with more than a million features
- Initial release of sketching tools
- OGC enhancements - WMS and WMTS layers can now be visualized in a 3D scene
Fast feature layer rendered with WebGL (beta)
In the new version 3.22 of the ArcGIS API for JavaScript there are configurable point clustering as a highlight and some API updates.
