Version 4.32 is here. There are bug fixes, enhancements, and new functionality. By the numbers: we fixed 23 bugs, made 17 enhancements, added or updated 21 samples, and optimized 12 components.   Components. What are components? As the kids say, IYKYK, which loosely translates to, “If you get it, you get it”. Let’s break it down a bit (skip ahead if you’re already in the know). Components are a better way to reuse code, and can also be a better way to code. Here’s an agnostic source to reference: https://developer.mozilla.org/en-US/docs/Web/API/Web_components Here’s a really handy migration page that documents helpful concepts: https://developers.arcgis.com/javascript/latest/migrating-to-components/ Here’s the transition guide to help move from widgets to components: https://developers.arcgis.com/javascript/latest/components-transition-plan/ And, we have a really awesome blog post coming soon from @JuliePowell that I will share a link to here after it gets posted on the ArcGIS Blog site: https://www.esri.com/arcgis-blog/products/js-api-arcgis/developers/javascript-maps-sdk-a-full-transition-to-components/ You can also go to the Tutorials and discover how many of them we migrated to use components: https://developers.arcgis.com/javascript/latest/tutorials/ Want something beefier than a tutorial? Check out how many samples we got updated too: https://developers.arcgis.com/javascript/latest/sample-code/?tagged=map-components Oh I know, you’re like what’s up with the SDK Reference? References-small.png Well, we put the Core API and the Components on the same page. Pretty handy, right? So much easier and nicer. Thanks Lloyd. References-page.png   Display filters. You want like the power of a definition expression, but to only affect the visibility on the map and not the filter the data from the source? That’s what a display filter is for. It’s new and it’s fabulous (and yes, it is now supported by the print service). https://developers.arcgis.com/javascript/latest/sample-code/display-filter/ Screenshot 2025-02-24 at 2.52.50 PM.png   New highlights, no lowlights. Features can now be highlighted with different colors based on stuff. Used to be only one, now it can be more. https://developers.arcgis.com/javascript/latest/release-notes/#enhanced-highlights-api highlights.png   Tracking. We all have histories. Especially time aware layers. Visit or revisit those histories across time and space (and no, not currently supported by the print service). https://developers.arcgis.com/javascript/latest/release-notes/#track-rendering-beta   Heading in the right Directions. Directions UI is updated with Calcite. Can now add/move/delete stops and polyline barriers. There’s probably a really good official blog post about this coming out soon; I will link to it here later. https://developers.arcgis.com/javascript/latest/sample-code/widgets-directions/ DW1.png   Knowledge Graphs and Web Link Charts. Knowledge graphs allow you to model real-world systems that connects both spatial and nonspatial data. Also included are knowledge graph layers, which represent knowledge graph data on a map to enhance visualization and analysis.  Additionally, web link charts contain a link chart layer with the data from your knowledge graph and are loaded in a link chart view. Web link charts are a new view (like MapView and SceneView) that is specifically for visualization knowledge graphs.  https://developers.arcgis.com/javascript/latest/release-notes/#knowledge-graphs-and-web-link-charts link-chart-layouts.png   Editing has only one “t”. Editting is the sort of word I misspell constantly. But wow, the Editing team installed some heavy work this release. Like enhancing workflows to accommodate layers and sublayers and types and subtypes and sublayers of subtypes and like group tables, oh my... You can share editing templates now, you can use the new drawing toolbar in the Editor widget, and there’s even snappy support for those new display filters. AND YOU CAN ADD AND/OR DELETE UTILITY NETWORK ASSOCIATIONS NOW?! I just read through the release notes and I can’t believe how much work we got done. Take a look. https://developers.arcgis.com/javascript/latest/release-notes/#editing   Operating geometrically. Those smooth geometry operators that came out in beta at 4.31 and coming out of beta at 4.32. We have a guide page for them. Essentially, did you use geometry engine? Then please read this because you’ll want to migrate… smoothly. https://developers.arcgis.com/javascript/latest/spatial-analysis/intro-geometry-operators/   Tired of reading this? Understandable, we released a lot. But, there are a still a TON of more updates at 4.32. As an example, here is what is left in the TOC from the release notes that we haven’t covered yet: NoahSager_0-1740430195360.png   Head to the release notes to learn more. https://developers.arcgis.com/javascript/latest/guide/release-notes/index.html   References.   Release Blog https://www.esri.com/arcgis-blog/products/js-api-arcgis/developers/whats-new-in-arcgis-maps-for-javascript-4-32/   4.32 Release Notes https://developers.arcgis.com/javascript/latest/guide/release-notes/index.html   4.32 Samples https://developers.arcgis.com/javascript/latest/sample-code/?tagged=4.32   Tips for migrating to Components https://developers.arcgis.com/javascript/latest/migrating-to-components/   Blog for migrating to Components https://www.esri.com/arcgis-blog/products/js-api-arcgis/developers/javascript-maps-sdk-a-full-transition-to-components/   Breaking Changes across all 4x releases https://developers.arcgis.com/javascript/latest/guide/breaking-changes/index.html ...

Version 4.31 is here, and it’s so good. There are bug fixes, enhancements, and new functionality. But make sure you’re sitting down, because it’s a lot. By the numbers: we fixed 65 bugs, made 19 enhancements, and added or updated 29 samples.   Component enhancements What are components? Components are reusable custom elements that can be used in one or more web applications. They can make writing apps easier (fewer lines of code) and are designed to work well with frameworks. They’re pretty cool, pretty modern, and we made ours better. If you haven’t checked them out yet, or if you’re feeling down and want to take your mind off things, then today is the perfect opportunity to check out our component enhancements. components.jpg https://developers.arcgis.com/javascript/latest/release-notes/ - component-enhancements   SceneView Icon Rotation Speaking of cool and modern, you can now rotate 2D billboarded icons within a 3D SceneView. icons.gif https://developers.arcgis.com/javascript/latest/sample-code/visualization-icon-rotation-3d/   Featuring the FeatureTable Unlike my favorite professional sports team, the FeatureTable got a lot of love recently. First, you can now export selected records to a CSV file. Note that geometry information is only included for point geometries. You can also view and modify attachments, support pagination (multiple pages), edit subtype values, configure and persist display settings, and (maybe? probably?) more. https://developers.arcgis.com/javascript/latest/sample-code/?tagged=TableTemplate   Animated symbols If the above topic was too serious for some readers, consider the new CIMSymbol symbol animations (in beta). CIMcymbals.gif https://developers.arcgis.com/javascript/latest/sample-code/cim-animations/   Aggregation Aggravations? Back in the day, only point geometries could be aggregated into clusters and bins. Now, we are open to both polygon and polyline geometries being aggregated. It’s a new day. https://developers.arcgis.com/javascript/latest/release-notes/ - polyline-and-polygon-geometries-can-now-be-aggregated-to-bins-and-clusters   Smooth Geometry Operators Unlike telephone operators, the Geometry operators are new, helpful for working with the ArcGIS Maps SDK for JavaScript, and currently available in beta. These are the eventual replacements for the GeometryEngine. The new operators include all the old hits from GeometryEngine, plus a few new ones. geoemtry-operators.png https://developers.arcgis.com/javascript/latest/release-notes/ - geometry-operators-beta   The Missing Link Chart A link chart visually represents all or part of a knowledge graph. A knowledge graph allows you to create a model that simulates a real-world system in a nonspatial manner, in ArcGIS Enterprise using ArcGIS Pro. But now you can add link charts to an app using a variety of methods, which is nice. Linkcharts.png https://developers.arcgis.com/javascript/latest/release-notes/ - link-chart   Scene Saving SceneLayer, BuildingSceneLayer, IntegratedMeshLayer, and PointCloudLayer can now be saved to a portal item in ArcGIS Online and/or ArcGIS Enterprise. Before 4.31, you couldn’t do this. This is also true for OrientedImageryLayer, but that’s a 2D and a 3D thing. https://developers.arcgis.com/javascript/latest/release-notes/ - layer-updates   High Visibility Areas MapView and SceneView now have a visibleArea property, providing access to the visible portion of the map as a Polygon that can be inset into the app. The polygon is a 2D approximation of the 3D frustum projected onto the ground surface.  inset.png https://developers.arcgis.com/javascript/latest/release-notes/ - mapview-and-sceneview-visible-area   Is There More? Yes, a lot more.

Upload to a portal, lost in fervor? If you’re outsourcing work, user, I think it’s great But while we’re at 4.31 I think I’ll take my labels neat My 3D icons, and my rotating //MapView go to me MapView.goTo(me);   I take my labels neat My 3D icons, and my rotating //MapView go to me MapView.goTo(me);   FeatureTable And edit related records are enabled Feature on the map and then I apply a label And the task gets done But you’ll debug some, I know   But who wants to work forever, right? AI’s coming in the dead of night Now I know why they call it smart mapping   Symbol animations come along User, don’t get me wrong You know SceneView supports time, as well as viewshed, not only points support clusters, Geometry operators are great If you can npm install me, maybe I’ll await Until that date I’d rather take my labels neat My 3D icons, and my rotating //MapView go to me MapView.goTo(me);   I take my labels neat My 3D icons, and my rotating //MapView go to me MapView.goTo(me);   I take my labels neat My 3D icons, and my rotating //MapView go to me MapView.goTo(me);   References Release Blog https://www.esri.com/arcgis-blog/products/js-api-arcgis/announcements/whats-new-in-arcgis-maps-sdk-for-javascript-4-31/ 4.31 Release Notes https://developers.arcgis.com/javascript/latest/guide/release-notes/index.html 4.31 Samples https://developers.arcgis.com/javascript/latest/sample-code/?tagged=4.31 Breaking Changes across all 4x releases https://developers.arcgis.com/javascript/latest/guide/breaking-changes/index.html Song inspiration https://www.youtube.com/watch?v=aezstCBHOPQ Fair use and Parody law https://en.wikipedia.org/wiki/Fair_use ...
