ArcGIS API 4 for JavaScript Released: What’s New for Developers

Esri, an international company that provides Geographic Information System (GIS) software, announced version 4.0 production release of ArcGIS API for JavaScript on Tuesday.

This is the first release of of the 4.x series which is a new rendering of the JavaScript API that Esri decided to launch in addition to the 3.x series. The new 4.x series is aimed to be easier in use as a JavaScript API and support both 2D and 3D visualization.

3D and 2D Made Easy to Use

New version 4.0 of ArcGIS API for JavaScript is suitable for 3D scenes and 2D maps development. It enables developers to build full featured 3D application which can include such rich information layers as terrain, basemaps, imagery, features, and 3D objects.

The APi also includes some core capabilities to create 2D applications. The programming patterns to work with 3D and 2D are very similar and unified. With map views, developers can render a map with either a 2D or a 3D view (or both of them) adding just a few lines of code. In some cases you can even use the same code for both 2D or 3D views as they share the same implementation for layers, navigation, pop¬ups, tasks, symbology, geometry, etc.

But note that not all 2D capabilities that are supported in the 3.x API are supported in the first release of 4.x series (version 4.0). So you should consider requirements for your application to choose the right API version to work with.

Mobile First Approach for User-Friendly Apps 

API 4.0 allows to build applications with responsive design and awesome user interfaces for any device. Widgets are flexible UI building blocks that can be placed wherever it is needed to adapt to different screen resolutions and this provides clean and polished user experience. The API widgets can be used as they are or styled with CSS easily.

Simpler and More Consistent API Design

ArcGIS API 4 for JavaScript offers a cleaner implementation, better customization and integration with third-party frameworks, what results in improved overall developer experience.

Version 4.0 has a lot of improvements and design changes. You can find more information on the official website.
