We've experimented with comlink and Vite/rollup. We'll have a sample app for that when 4.33 releases in the next 30 days or so. You might give it a try with Angular and let us know: https://github.com/GoogleChromeLabs/comlink. ... View more

@MichaelWen_Timmons  typically 404 errors indicate something is not configured correctly. Verify the assets were actually copied: https://developers.arcgis.com/javascript/latest/get-started-npm/#local-assets. Please provide a minimal reproduction sample. Here's our troubleshooting guide for future reference. ... View more

Please provide a minimal repro sample, there's more info on that here: https://developers.arcgis.com/javascript/latest/troubleshooting/#minimal-reproducible-application. One suggestion is to first build the custom layer in JavaScript, and then migrate your code to TypeScript.  Did you try adding a load() method. There are several samples to use for guidance: https://developers.arcgis.com/javascript/latest/sample-code/layers-custom-tilelayer/ , https://developers.arcgis.com/javascript/latest/sample-code/layers-custom-blendlayer/ and https://developers.arcgis.com/javascript/latest/sample-code/layers-custom-elevation-exaggerated/. > I don't suppose a dojo-less typescript version is on the cards, is it?  There hasn't been any dojo in the 4.x API in quite a while, and it was removed from the CDN in version 4.25. ...

@bearingwestlooks like I never clarified my answer from above. If you are using TypeScript with '@arcgis/core', then the error "Property 'createSubclass' does not exist on type 'typeof SomeXYZLayer'" is correct when attempting to use the createSubclass() method. The createSubclass() method only works in JavaScript. We updated the documentation about subclassing in TypeScript here: https://developers.arcgis.com/javascript/latest/implementing-accessor/#create-a-simple-subclass.   The correct pattern in TypeScript would look like the following. You might also need to set 'useDefineForClassFields:false' in your tsconfig, depending on your project configuration. import { subclass } from "@arcgis/core/core/accessorSupport/decorators"; import BaseTileLayer from "@arcgis/core/layers/BaseTileLayer.js"; @subclass("custom.MyTileLayer") export class MyTileLayer extends BaseTileLayer { // TODO }   ...

@FC_Basson, thanks for the heads-up. I'll open an issue to get that added at 4.33. I'm not sure why the property didn't get exposed in the component. ... View more

Good catch on the wording, I'll blend your suggestions in. We agree that some of the wording could use "fine tuning". The first phase was to get all 60+ new operators into the API, now we are in the enhancement phase. ... View more

@shiyanlim  thanks for the feedback and sorry about the frustration. Many doc improvements are coming in the 4.32 release, which is tentatively scheduled for later this month. For example, both the components and core API references will be integrated as you expect them to be. There's updated tutorials and more. ... View more

@JoeBessettecan you clarify, are these top-level awaits in your custom code? And what version of Safari? It would be great if you can provide a simple repro app/project, otherwise not much troubleshooting we can do. ... View more

Hi @rhughes522  please provide a minimal reproducible application. You can capture the feature record's geometry and manually create a polygon from it in the repro app. Here are some guidelines: https://developers.arcgis.com/javascript/latest/troubleshooting/#minimal-reproducible-application. ...

@JavidYousafand @BillMitchell  can someone provide a minimal repro sample where skipLibCheck is true and you still see the errors? The core Angular sample is the best starting point: https://github.com/Esri/jsapi-resources/tree/main/core-samples/jsapi-angular-cli. Here's our recommendations for creating and sharing the sample: https://developers.arcgis.com/javascript/latest/troubleshooting/#minimal-reproducible-application. ... View more

Angular 18+ defaults to using esbuild for production builds. The large number of files is a known issue with Angular, unrelated to the ArcGIS SDK for JavaScript, because of esbuild code splitting. We also document this issue here: https://github.com/Esri/jsapi-resources/tree/main/core-samples/jsapi-angular-cli#known-issues.  In theory, you can still use Webpack with Angular 19, for example: https://www.npmjs.com/package/@angular-builders/custom-webpack. I don't have any experience with that builder, but you might look around. Or maybe another community member with experience can jump in and share their experience. For the best performance, make sure your server is using HTTP/2 (or HTTP/3) and that your browser version(s) are on the SDK's browser support list: https://developers.arcgis.com/javascript/latest/system-requirements/#supported-browsers. Modern browsers are generally quite performant when combined with the latest HTTP protocols. You can see a comparison of the various build tools and various build/performance numbers here: https://github.com/Esri/jsapi-resources/blob/main/core-samples/.metrics/4.31.0.csv. ... View more

@NicolasGIS  as you noted, there isn't a 1:1 relationship between the AMD CDN and a local build of the "@arcgis/core" ES modules. Those use two different module systems, so comparing them side-by-side will always result in different performance profiles. In reviewing the jsapi-custom-worker sample, the network requests and overall performance appear to be working as-designed for "@arcgis/core". I tested the sample locally on my laptop using 4.31, and I didn't see any http request browser stalls. There's definitely a pause when the spatial-join.worker runs, but that's also expected. As I mentioned above, you'll need to use a tool such as Charles debugging proxy to help distinguish between actual http requests and requests are cached by the browser. The chrome developer console tools aren't always telling the full story. Some things you can do on your end to ensure the best performance when building the SDK locally: Host your local build on a CDN If you are hosting the build on your own web server: Make sure your web server is using HTTP/2 If using HTTP/1 set the “Keep-Alive” header ...
