Update - this looks like a regression at 4.25, thanks for reporting. We've opened an issue to fix it.

Hi @AriefAbuBakar it's very possible that your code was working accidentally. You need to use the "extends" keyword when building subclasses with ES modules: https://developers.arcgis.com/javascript/latest/implementing-accessor/#create-a-simple-subclass. It can be challenging when overriding API functionality because properties, methods and patterns within the underlying API Class are subject to change. // Psuedo-example using @arcgis/core ES modules class ExampleWebTileLayer extends WebTileLayer { constructor(properties?:any) { super(properties); } . . . }

@YueZhou1what you are seeing with init.js is the API spinning up multiple workers. I can see how that would give the impression there is a caching problem. We ran tests and the API worker initialization caching is working correctly. If you are still having issues, the next steps would be to open a tech support ticket, or call your account representative to meet with a solutions engineer.

All good info, thanks for sharing your experience. Yes, there is a known issue with Stencil because it has it's own assetsPath setting that conflicts with @ArcGIS/core.

Hi @Justin_Greco we aren't able to access your repo, it might be set to private. You might need to use setAssetPath for Calcite as mentioned here: https://developers.arcgis.com/calcite-design-system/get-started/#custom-elements?. If you give that a try, let us know if it helps?

Hi @ae my recommendation is provide a simple github repo that you can share and that reproduces the issue. Since that is most likely a recursion error we'll need an example.

Hi @DanielWebb, good questions, they related to both the AMD and ES modules: 1. No. You can use esri/request or use native fetch directly to load HTML as a string into your app 2. This can be handled through industry-standard patterns such as using Etags. You can also set the cacheBust option in esri/request, but this is a different implementation from dojo, instead of adding a param, it tells fetch to make a conditional request. If you always want to cacheBust, then you can use a requestInterceptor with the url set to null. 3.You can remove event listeners natively. If you are using an "on" listener, you can remove those using the APIs remove() method.

Hi @Yue_Zhou can you provide more information on your use case for needing that many CPU cores? That's definitely a non-standard hardware configuration for a single web browser user. 80 cores would be more typical for a server-side implementation, or a host VDI machine with dozens or hundreds of users. In the meantime, thanks for reporting, we'll take a look at the top limit.

If it's a custom JS app we will need a link to a simple github repo, codesandbox or stackblitz.com sample. If you need a basic Angular + ArcGIS JS API sample as a starting point, we recommend using this one: https://github.com/Esri/jsapi-resources/tree/master/esm-samples/jsapi-angular-cli.

Hi @ConnerFarrant are you building a custom ArcGIS JS API app or using an ArcGIS Dashboard? If you are using a Dashboard, you'll need to follow that product's System Requirements and Tech Support procedures. Here's a link to the ArcGIS Dashboard community site if you need to reach out to them for more guidance.

Hi @AbdulSamim these types of errors are typically related to project configuration, and not a bug in the ArcGIS JS API. Please provide a link to a simple github repository that reproduces the issue.

Hi @AbdulSamim check to see if you have .wasm configured in your local webserver: https://developers.arcgis.com/javascript/latest/install-and-set-up/#web-server-hosting-configuration

Hi @daltvr for localizing the various elements that belong to the ArcGIS JS API, see this guide topic: https://developers.arcgis.com/javascript/latest/localization/. The API widgets use their own localization strings.

> is not an ESRI Api Key, but an API Key for an Azure API Management component Gotcha. You'll need to contact Azure technical support since that's their product. We don't have any control or knowledge of their security practices.

@NicolasSwijngedouwIf you inject unauthorized headers it will cause a CORS pre-flight error. Here are a few resources to check out on the coding patterns for using API keys: https://developers.arcgis.com/javascript/latest/secure-resources/#api-keys, https://developers.arcgis.com/documentation/mapping-apis-and-services/security/api-keys/ and https://developers.arcgis.com/javascript/latest/display-a-map/#get-an-api-key
