We are excited to announce that beta 2 of the ArcGIS API for JavaScript 4.0<\/a> is now available.<\/p>\n

We have been busy working on adding functionality to the next generation JavaScript API, which includes new layer types, a redesigned popup experience, support for reading Web Scenes, new tasks, widgets, security, and more. For all the details on what’s new in this release, see the What’s New in Version 4.0 beta 2<\/a>\u00a0page.<\/p>\n

<\/p>\n

The following are some of the highlights of this release.<\/p>\n

VectorTileLayer<\/h1>\n

Vector tile layers display cached data similar to image tiles, but they store a vector representation of the data. Client-side drawing of vector tiles allows for customizing the style of the layer which can drive dynamic, interactive cartography. For more information see the VectorTileLayer<\/a> documentation in the API Reference and the Vector tile layers<\/a> topic in the ArcGIS Online Help.<\/p>\n

\"\"<\/a><\/p>\n

Popups<\/h1>\n

We redesigned the popup experience to enhance the interactivity of mapping applications. They are responsive to device size, making them more mobile friendly. Developers can customize options to dock the popup in the view, create actions within the popup, and have more control over the popup behavior. See the following three examples for more details on what may be accomplished with the new popup.<\/p>\n

Popup actions<\/strong><\/p>\n

The Popup widget may contain actions, or buttons, that allow users to execute functions when clicked.<\/p>\n

\"\"<\/a><\/p>\n

Dock your popups<\/strong><\/p>\n

By default the popup docks automatically based on screen size. The developer can further customize options for popup placement and docking.<\/p>\n

\"\"<\/a><\/p>\n

Advanced Popups<\/strong><\/p>\n

You can easily control the popup’s content, location, and visibility. For example, the popup can be used to show custom content or analysis results.<\/p>\n

\"\"<\/a><\/p>\n

Web Scenes<\/h1>\n

Reading Web Scenes<\/strong><\/p>\n

The API adds support for reading Web Scenes. All you need to do is reference the ID of the Web Scene:<\/p>\n

\/\/ Modules required: <\/span>\r\n\/\/ esri\/WebScene<\/span>\r\n\/\/ esri\/portal\/PortalItem<\/span>\r\n\r\nvar<\/span> scene = new<\/span> WebScene({\r\n  portalItem: new<\/span> PortalItem({\r\n    id: \"affa021c51944b5694132b2d61fe1057\"<\/span>  \/\/ID of the WebScene on arcgis.com\/portal<\/span>\r\n  })\r\n});<\/pre>\n
You can programmatically interact with the various properties of the scene including its layers, environment settings, and slides.<\/p>\n
Local Web Scene support<\/strong><\/p>\n
Local scenes are the best way to show your regional or local data in a projected coordinate system. This includes support for mapping subsurface features and navigating below the surface. The following sample demonstrates this by mapping earthquakes and oil and gas well locations below the surface of the ground.<\/p>\n
\"\"<\/a><\/p>\n
Layers<\/h1>\n
Image layer support<\/strong><\/p>\n
The ArcGISImageLayer<\/a> gives you the ability to display, process, and render pixels from an ArcGIS image service. This is useful when you need to interactively manipulate pixel values and get an immediate response in the browser. See the sample referenced below for an example of using pixel filter to render pixel values on a two-color ramp.<\/p>\n
\"\"<\/a><\/p>\n
Dynamic layer support<\/strong><\/p>\n
In addition to tiled services and image services, you can access dynamic map services using ArcGISDynamicLayer<\/a>.<\/p>\n
\"\"<\/a><\/p>\n
Tasks<\/h1>\n
The following tasks are also part of this release.<\/p>\n
