Version 4.12 is released!

Version 4.12 of the ArcGIS API for JavaScript represents a whole new edition of the JavaScript API that integrates 2D and 3D into a single easy to use and powerful API.

Choose between version 3.29 and 4.12

The 4.x API introduces new capabilities such as 3D support, map rotation, and deeper portal integration. However, not all 3.x capabilities are included in the initial 4.x release. Developers should consider their app requirements and evaluate whether the current 4.x or 3.x release has the desired capabilities.

What's New in 3.29

The ArcGIS API for JavaScript is designed to maximize your productivity for building engaging, beautiful web mapping applications. The API combines modern web technology and powerful geospatial capabilities enabling you to create high-performing apps and smarter visualizations of your data.
