Apply layer-based scale ranges<\/a><\/h2>\nSeamless visibility switches between different layer types based on the scale are now possible in 3D. Many layers, including feature layers and scene layers (Point), now support layer-based scale ranges. While scale ranges were used in 3D prior to this release, visibility was determined feature-by-feature so you would have a mix of parts of layers at times. With this release, you can apply scale ranges that are evaluated per layer so that now the whole layer is either visible or invisible. This enables a more consistent and predictable experience for displaying a specific visualization of your data based on scale.<\/span><\/p>\nCheck out the example below which demonstrates toggling the visibility of layers at a specific scale settings. Accident locations are first visualized as a heatmap displayed over the Topographic 3D Basemap. As you zoom in (scale < 1000), accidents are shown as individual points and the Topographic 3D Basemap is turned off in favor of the integrated mesh 3D tiles layer. This switch gives the user a more detailed real-world context and helps them gain insights into where and potentially why the accidents occurred.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2850192,"id":2850192,"title":"layer_based_scale_range","filename":"layer_based_scale_range.gif","filesize":6304608,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/js-api-arcgis\/announcements\/whats-new-in-arcgis-maps-sdk-for-javascript-4-33\/layer_based_scale_range","alt":"","author":"330302","description":"","caption":"As you zoom in, accidents are shown as individual points instead of hot spot and the Topographic 3D Basemap is turned off in favor of the integrated mesh 3D tiles layer, providing real-world context for the users.","name":"layer_based_scale_range","status":"inherit","uploaded_to":2808342,"date":"2025-06-24 05:14:46","modified":"2025-06-24 05:22:21","menu_order":0,"mime_type":"image\/gif","type":"image","subtype":"gif","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":960,"height":540,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range-213x200.gif","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","medium-width":464,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","medium_large-width":768,"medium_large-height":432,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","large-width":960,"large-height":540,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","1536x1536-width":960,"1536x1536-height":540,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","2048x2048-width":960,"2048x2048-height":540,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range-826x465.gif","card_image-width":826,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","wide_image-width":960,"wide_image-height":540}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

This enables better understanding of the amount of time something is in shadow during the day.<\/span><\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2839012,"id":2839012,"title":"shadowcast_discrete_context_rn_poster","filename":"shadowcast_discrete_context_rn_poster.png","filesize":826693,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/js-api-arcgis\/announcements\/whats-new-in-arcgis-maps-sdk-for-javascript-4-33\/shadowcast_discrete_context_rn_poster","alt":"","author":"4271","description":"","caption":"","name":"shadowcast_discrete_context_rn_poster","status":"inherit","uploaded_to":2808342,"date":"2025-06-17 17:34:53","modified":"2025-06-17 17:34:53","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":1920,"height":1080,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","medium-width":464,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","medium_large-width":768,"medium_large-height":432,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","large-width":1920,"large-height":1080,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster-1536x864.png","1536x1536-width":1536,"1536x1536-height":864,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","2048x2048-width":1920,"2048x2048-height":1080,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster-826x465.png","card_image-width":826,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","wide_image-width":1920,"wide_image-height":1080}},"image_position":"center","orientation":"horizontal","hyperlink":"https:\/\/developers.arcgis.com\/javascript\/latest\/sample-code\/shadow-cast\/"},{"acf_fc_layout":"content","content":"Integrate and analyze oriented imagery<\/a><\/h2>\nEnhanced measurement capabilities<\/strong>: New triangulated measurement tools enable users to calculate distance, area, and location by intersecting vectors from measurement points captured from two different viewpoints.

Display a parquet file (beta)<\/a><\/h2>\nThe\u00a0ParquetLayer<\/a>\u00a0(beta) enables visualization of\u00a0parquet files<\/a>\u00a0on a map. In upcoming releases, we plan to expand support to include additional capabilities, such as feature querying.<\/p>\nBuild faster apps<\/a><\/h2>\nWe constantly work to optimize performance in any way possible. This release, we improved performance in the following areas:<\/p>\n
Feature layers<\/strong>: Polygon, polyline, and multipoint features load faster when panning and zooming in 2D maps. ArcGIS Online-hosted feature layers retrieve all features from the server upon initial map load when specific conditions are satisfied. Once loaded, the features don’t need to be re-requested from the server, avoiding future redraws when panning and zooming.<\/p>\nDictionary renderer<\/strong>: Significant performance improvement was achieved by optimizing how symbols are computed and cached. Instead of generating a unique symbol for each feature, the renderer now reuses symbols when possible and performs more precomputations up front.<\/p>\n3D scenes<\/strong>: For raster tile layers and select gltf model textures, we now automatically compress loaded images in the browser. This saves 75% of the uncompressed memory used previously. Compression happens asynchronous and in parallel in web workers, thus coming at no cost to performance in existing web applications. In addition to other optimizations, this leads to memory savings of 10-50% in typical web scenes.<\/p>\nProgramming pattern updates<\/h2>\n
The SDK offers power and flexibility, constantly pushing the boundaries of what’s possible through innovation of functionality and evolving programming patterns. Over the last several releases, we have been advancing the SDK\u2019s component and core API design. While this transition empowers you with efficient and elegant ways to develop, it also necessitates adapting existing code to align with these evolving patterns. Some of the updates below are specifically designed to provide developers with a smooth transition to components, while others are introducing a more modern approach for an existing pattern.<\/p>\n
Embracing web component standards<\/strong>: The recommended approach for building web apps with the SDK is to use\u00a0components<\/a>. Core widget functionality is already available as components. Initially, widgets were wrapped within web components. Over time, we are incrementally refactoring them to not include the preexisting widget architecture and further embrace web component standards. For example, style encapsulation via the\u00a0shadowDOM<\/a>. Once a component has undergone this optimization, the corresponding widget is deprecated. This release includes\u00a0many components<\/a>\u00a0that meet this criteria. See\u00a0Esri’s move to web components<\/a>\u00a0for more information about the widget transition period and future.<\/p>\nReactive components<\/strong>: ArcGIS Maps SDK components properties are now watchable with\u00a0reactiveUtils<\/a>, the same utility used to observe changes in core API properties. Use\u00a0reactiveUtils.watch(),\u00a0.on(),\u00a0.once(),\u00a0.when(), or\u00a0.whenOnce()\u00a0to observe component state exactly as you would watch\u00a0view.zoom\u00a0or\u00a0layer.loaded. This provides developers who are migrating a widget-based application to components with a familiar way to observe changes on component properties.<\/p>\nSee the updated guide on\u00a0watching for components changes using reactiveUtils<\/a>.<\/p>\nWaiting for views to be ready:<\/strong> The new viewOnReady\u00a0method on the\u00a0Map<\/a>,\u00a0Scene<\/a>, and\u00a0Link Chart<\/a> components allows you to wait until the component’s internal view is fully initialized and ready to be used. This is useful when you are dynamically importing other modules or setting up logic that depends on the view being fully initialized. This method behaves similarly to watching the\u00a0arcgisViewOnReady\u00a0event, but it is more convenient for use in vanilla JavaScript applications. See the table in the\u00a0watching for changes guide<\/a>\u00a0to understand which method best suits your architecture.<\/p>\nModernize with $arcgis.import():<\/strong> The new $arcgis.import() global function is a modern replacement for AMD require when building single page JavaScript apps using the CDN. The function accepts a module path or an array of module paths and returns a promise that resolves with the requested module(s). The documentation has been updated to use this new pattern, including getting started<\/a>,\u00a0tutorials<\/a>\u00a0and\u00a0samples<\/a>. While require is still supported, we encourage developers to adopt this more practical and modern approach.<\/p>\nNew CDN endpoint for components<\/strong>: The CDN endpoint for component packages has been updated, offering a more consistent and simplified versioning pattern.<\/p>\nNew pattern:\u00a0https:\/\/js.arcgis.com\/{version-number}\/{component-package}\/<\/p>\n
Consider using geometry operators<\/strong>: The\u00a0geometry engine\u00a0has been deprecated in favor of the more modular and feature-rich\u00a0geometry operators. See the\u00a0Introduction to geometry operators guide page<\/a>\u00a0for more information.<\/p>\nLearn more<\/h2>\n
There is a lot more to this release, such as video layer enhancements, utility network associations with spatial selection, new geometric effects in vector symbols, and client-side point cloud layer queries. Continue learning about this massive release in the release notes<\/a>, and play around with the new capabilities using new samples<\/a>.<\/p>\n"},{"acf_fc_layout":"kaltura","video_id":"1_8noyzdny","time":false,"start":0,"stop":""},{"acf_fc_layout":"content","content":"

Apply layer-based scale ranges<\/a><\/h2>\nSeamless visibility switches between different layer types based on the scale are now possible in 3D. Many layers, including feature layers and scene layers (Point), now support layer-based scale ranges. While scale ranges were used in 3D prior to this release, visibility was determined feature-by-feature so you would have a mix of parts of layers at times. With this release, you can apply scale ranges that are evaluated per layer so that now the whole layer is either visible or invisible. This enables a more consistent and predictable experience for displaying a specific visualization of your data based on scale.<\/span><\/p>\nCheck out the example below which demonstrates toggling the visibility of layers at a specific scale settings. Accident locations are first visualized as a heatmap displayed over the Topographic 3D Basemap. As you zoom in (scale < 1000), accidents are shown as individual points and the Topographic 3D Basemap is turned off in favor of the integrated mesh 3D tiles layer. This switch gives the user a more detailed real-world context and helps them gain insights into where and potentially why the accidents occurred.<\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2850192,"id":2850192,"title":"layer_based_scale_range","filename":"layer_based_scale_range.gif","filesize":6304608,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/js-api-arcgis\/announcements\/whats-new-in-arcgis-maps-sdk-for-javascript-4-33\/layer_based_scale_range","alt":"","author":"330302","description":"","caption":"As you zoom in, accidents are shown as individual points instead of hot spot and the Topographic 3D Basemap is turned off in favor of the integrated mesh 3D tiles layer, providing real-world context for the users.","name":"layer_based_scale_range","status":"inherit","uploaded_to":2808342,"date":"2025-06-24 05:14:46","modified":"2025-06-24 05:22:21","menu_order":0,"mime_type":"image\/gif","type":"image","subtype":"gif","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":960,"height":540,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range-213x200.gif","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","medium-width":464,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","medium_large-width":768,"medium_large-height":432,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","large-width":960,"large-height":540,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","1536x1536-width":960,"1536x1536-height":540,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","2048x2048-width":960,"2048x2048-height":540,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range-826x465.gif","card_image-width":826,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/layer_based_scale_range.gif","wide_image-width":960,"wide_image-height":540}},"image_position":"center","orientation":"horizontal","hyperlink":""},{"acf_fc_layout":"content","content":"

Display a parquet file (beta)<\/a><\/h2>\nThe\u00a0ParquetLayer<\/a>\u00a0(beta) enables visualization of\u00a0parquet files<\/a>\u00a0on a map. In upcoming releases, we plan to expand support to include additional capabilities, such as feature querying.<\/p>\nBuild faster apps<\/a><\/h2>\nWe constantly work to optimize performance in any way possible. This release, we improved performance in the following areas:<\/p>\n
Feature layers<\/strong>: Polygon, polyline, and multipoint features load faster when panning and zooming in 2D maps. ArcGIS Online-hosted feature layers retrieve all features from the server upon initial map load when specific conditions are satisfied. Once loaded, the features don’t need to be re-requested from the server, avoiding future redraws when panning and zooming.<\/p>\nDictionary renderer<\/strong>: Significant performance improvement was achieved by optimizing how symbols are computed and cached. Instead of generating a unique symbol for each feature, the renderer now reuses symbols when possible and performs more precomputations up front.<\/p>\n3D scenes<\/strong>: For raster tile layers and select gltf model textures, we now automatically compress loaded images in the browser. This saves 75% of the uncompressed memory used previously. Compression happens asynchronous and in parallel in web workers, thus coming at no cost to performance in existing web applications. In addition to other optimizations, this leads to memory savings of 10-50% in typical web scenes.<\/p>\nProgramming pattern updates<\/h2>\n
The SDK offers power and flexibility, constantly pushing the boundaries of what’s possible through innovation of functionality and evolving programming patterns. Over the last several releases, we have been advancing the SDK\u2019s component and core API design. While this transition empowers you with efficient and elegant ways to develop, it also necessitates adapting existing code to align with these evolving patterns. Some of the updates below are specifically designed to provide developers with a smooth transition to components, while others are introducing a more modern approach for an existing pattern.<\/p>\n
Embracing web component standards<\/strong>: The recommended approach for building web apps with the SDK is to use\u00a0components<\/a>. Core widget functionality is already available as components. Initially, widgets were wrapped within web components. Over time, we are incrementally refactoring them to not include the preexisting widget architecture and further embrace web component standards. For example, style encapsulation via the\u00a0shadowDOM<\/a>. Once a component has undergone this optimization, the corresponding widget is deprecated. This release includes\u00a0many components<\/a>\u00a0that meet this criteria. See\u00a0Esri’s move to web components<\/a>\u00a0for more information about the widget transition period and future.<\/p>\nReactive components<\/strong>: ArcGIS Maps SDK components properties are now watchable with\u00a0reactiveUtils<\/a>, the same utility used to observe changes in core API properties. Use\u00a0reactiveUtils.watch(),\u00a0.on(),\u00a0.once(),\u00a0.when(), or\u00a0.whenOnce()\u00a0to observe component state exactly as you would watch\u00a0view.zoom\u00a0or\u00a0layer.loaded. This provides developers who are migrating a widget-based application to components with a familiar way to observe changes on component properties.<\/p>\nSee the updated guide on\u00a0watching for components changes using reactiveUtils<\/a>.<\/p>\nWaiting for views to be ready:<\/strong> The new viewOnReady\u00a0method on the\u00a0Map<\/a>,\u00a0Scene<\/a>, and\u00a0Link Chart<\/a> components allows you to wait until the component’s internal view is fully initialized and ready to be used. This is useful when you are dynamically importing other modules or setting up logic that depends on the view being fully initialized. This method behaves similarly to watching the\u00a0arcgisViewOnReady\u00a0event, but it is more convenient for use in vanilla JavaScript applications. See the table in the\u00a0watching for changes guide<\/a>\u00a0to understand which method best suits your architecture.<\/p>\nModernize with $arcgis.import():<\/strong> The new $arcgis.import() global function is a modern replacement for AMD require when building single page JavaScript apps using the CDN. The function accepts a module path or an array of module paths and returns a promise that resolves with the requested module(s). The documentation has been updated to use this new pattern, including getting started<\/a>,\u00a0tutorials<\/a>\u00a0and\u00a0samples<\/a>. While require is still supported, we encourage developers to adopt this more practical and modern approach.<\/p>\nNew CDN endpoint for components<\/strong>: The CDN endpoint for component packages has been updated, offering a more consistent and simplified versioning pattern.<\/p>\nNew pattern:\u00a0https:\/\/js.arcgis.com\/{version-number}\/{component-package}\/<\/p>\n
Consider using geometry operators<\/strong>: The\u00a0geometry engine\u00a0has been deprecated in favor of the more modular and feature-rich\u00a0geometry operators. See the\u00a0Introduction to geometry operators guide page<\/a>\u00a0for more information.<\/p>\nLearn more<\/h2>\n
There is a lot more to this release, such as video layer enhancements, utility network associations with spatial selection, new geometric effects in vector symbols, and client-side point cloud layer queries. Continue learning about this massive release in the release notes<\/a>, and play around with the new capabilities using new samples<\/a>.<\/p>\n"},{"acf_fc_layout":"kaltura","video_id":"1_8noyzdny","time":false,"start":0,"stop":""},{"acf_fc_layout":"content","content":"

This enables better understanding of the amount of time something is in shadow during the day.<\/span><\/p>\n"},{"acf_fc_layout":"image","image":{"ID":2839012,"id":2839012,"title":"shadowcast_discrete_context_rn_poster","filename":"shadowcast_discrete_context_rn_poster.png","filesize":826693,"url":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","link":"https:\/\/www.esri.com\/arcgis-blog\/products\/js-api-arcgis\/announcements\/whats-new-in-arcgis-maps-sdk-for-javascript-4-33\/shadowcast_discrete_context_rn_poster","alt":"","author":"4271","description":"","caption":"","name":"shadowcast_discrete_context_rn_poster","status":"inherit","uploaded_to":2808342,"date":"2025-06-17 17:34:53","modified":"2025-06-17 17:34:53","menu_order":0,"mime_type":"image\/png","type":"image","subtype":"png","icon":"https:\/\/www.esri.com\/arcgis-blog\/wp-includes\/images\/media\/default.png","width":1920,"height":1080,"sizes":{"thumbnail":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster-213x200.png","thumbnail-width":213,"thumbnail-height":200,"medium":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","medium-width":464,"medium-height":261,"medium_large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","medium_large-width":768,"medium_large-height":432,"large":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","large-width":1920,"large-height":1080,"1536x1536":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster-1536x864.png","1536x1536-width":1536,"1536x1536-height":864,"2048x2048":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","2048x2048-width":1920,"2048x2048-height":1080,"card_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster-826x465.png","card_image-width":826,"card_image-height":465,"wide_image":"https:\/\/www.esri.com\/arcgis-blog\/app\/uploads\/2025\/05\/shadowcast_discrete_context_rn_poster.png","wide_image-width":1920,"wide_image-height":1080}},"image_position":"center","orientation":"horizontal","hyperlink":"https:\/\/developers.arcgis.com\/javascript\/latest\/sample-code\/shadow-cast\/"},{"acf_fc_layout":"content","content":" Enhanced measurement capabilities<\/strong>: New triangulated measurement tools enable users to calculate distance, area, and location by intersecting vectors from measurement points captured from two different viewpoints.

During playback, tools like footprint display, camera locations, and image enhancement are available.<\/p>\n Charts components (beta) include many minor but useful enhancements that improve both the developer experience and capabilities that you can enable in your apps. For example:<\/p>\n The\u00a0ParquetLayer<\/a>\u00a0(beta) enables visualization of\u00a0parquet files<\/a>\u00a0on a map. In upcoming releases, we plan to expand support to include additional capabilities, such as feature querying.<\/p>\n We constantly work to optimize performance in any way possible. This release, we improved performance in the following areas:<\/p>\n Feature layers<\/strong>: Polygon, polyline, and multipoint features load faster when panning and zooming in 2D maps. ArcGIS Online-hosted feature layers retrieve all features from the server upon initial map load when specific conditions are satisfied. Once loaded, the features don’t need to be re-requested from the server, avoiding future redraws when panning and zooming.<\/p>\n Dictionary renderer<\/strong>: Significant performance improvement was achieved by optimizing how symbols are computed and cached. Instead of generating a unique symbol for each feature, the renderer now reuses symbols when possible and performs more precomputations up front.<\/p>\n 3D scenes<\/strong>: For raster tile layers and select gltf model textures, we now automatically compress loaded images in the browser. This saves 75% of the uncompressed memory used previously. Compression happens asynchronous and in parallel in web workers, thus coming at no cost to performance in existing web applications. In addition to other optimizations, this leads to memory savings of 10-50% in typical web scenes.<\/p>\n The SDK offers power and flexibility, constantly pushing the boundaries of what’s possible through innovation of functionality and evolving programming patterns. Over the last several releases, we have been advancing the SDK\u2019s component and core API design. While this transition empowers you with efficient and elegant ways to develop, it also necessitates adapting existing code to align with these evolving patterns. Some of the updates below are specifically designed to provide developers with a smooth transition to components, while others are introducing a more modern approach for an existing pattern.<\/p>\n Embracing web component standards<\/strong>: The recommended approach for building web apps with the SDK is to use\u00a0components<\/a>. Core widget functionality is already available as components. Initially, widgets were wrapped within web components. Over time, we are incrementally refactoring them to not include the preexisting widget architecture and further embrace web component standards. For example, style encapsulation via the\u00a0shadowDOM<\/a>. Once a component has undergone this optimization, the corresponding widget is deprecated. This release includes\u00a0many components<\/a>\u00a0that meet this criteria. See\u00a0Esri’s move to web components<\/a>\u00a0for more information about the widget transition period and future.<\/p>\n Reactive components<\/strong>: ArcGIS Maps SDK components properties are now watchable with\u00a0reactiveUtils<\/a>, the same utility used to observe changes in core API properties. Use\u00a0reactiveUtils.watch(),\u00a0.on(),\u00a0.once(),\u00a0.when(), or\u00a0.whenOnce()\u00a0to observe component state exactly as you would watch\u00a0view.zoom\u00a0or\u00a0layer.loaded. This provides developers who are migrating a widget-based application to components with a familiar way to observe changes on component properties.<\/p>\n See the updated guide on\u00a0watching for components changes using reactiveUtils<\/a>.<\/p>\n Waiting for views to be ready:<\/strong> The new viewOnReady\u00a0method on the\u00a0Map<\/a>,\u00a0Scene<\/a>, and\u00a0Link Chart<\/a> components allows you to wait until the component’s internal view is fully initialized and ready to be used. This is useful when you are dynamically importing other modules or setting up logic that depends on the view being fully initialized. This method behaves similarly to watching the\u00a0arcgisViewOnReady\u00a0event, but it is more convenient for use in vanilla JavaScript applications. See the table in the\u00a0watching for changes guide<\/a>\u00a0to understand which method best suits your architecture.<\/p>\n Modernize with $arcgis.import():<\/strong> The new $arcgis.import() global function is a modern replacement for AMD require when building single page JavaScript apps using the CDN. The function accepts a module path or an array of module paths and returns a promise that resolves with the requested module(s). The documentation has been updated to use this new pattern, including getting started<\/a>,\u00a0tutorials<\/a>\u00a0and\u00a0samples<\/a>. While require is still supported, we encourage developers to adopt this more practical and modern approach.<\/p>\n New CDN endpoint for components<\/strong>: The CDN endpoint for component packages has been updated, offering a more consistent and simplified versioning pattern.<\/p>\n New pattern:\u00a0https:\/\/js.arcgis.com\/{version-number}\/{component-package}\/<\/p>\n Consider using geometry operators<\/strong>: The\u00a0geometry engine\u00a0has been deprecated in favor of the more modular and feature-rich\u00a0geometry operators. See the\u00a0Introduction to geometry operators guide page<\/a>\u00a0for more information.<\/p>\n There is a lot more to this release, such as video layer enhancements, utility network associations with spatial selection, new geometric effects in vector symbols, and client-side point cloud layer queries. Continue learning about this massive release in the release notes<\/a>, and play around with the new capabilities using new samples<\/a>.<\/p>\n"},{"acf_fc_layout":"kaltura","video_id":"1_8noyzdny","time":false,"start":0,"stop":""},{"acf_fc_layout":"content","content":"Create spike maps<\/a><\/h2>\n
