Is it possible to have crossorigin attribute when loading ArcGIS modules?

Hi @StreetStrider the short answer is no, there aren't any guaranteed client-side workarounds for this issue. We don't have any plans to change the behavior in the AMD CDN build. For troubleshooting, one suggestion is to tell Chrome to stop at all errors.

The only definitive fix would be to upgrade/migrate to @arcgis/core ES modules at some point.

But it seemes that this is not the only place that creates script elements, there's another place inside modules that comes from arcgis itself.

Right, you could potentially monkey patch require.injectUrl but it comes with the same challenges and caveats: https://github.com/dojo/dojo/blob/master/dojo.js#L1746

The resources repo might be a better place.

I see. This is considered to be a legacy build, if I'm right.

Actually I thought I would be able to workaround this by myself, by monkey patching loader here. But it seemes that this is not the only place that creates script elements, there's another place inside modules that comes from arcgis itself.

My last resort is to try to use mutationobserver / setinterval to put crossorigin attribute to loaded scripts, but it might not work and seemes quite tricky for my goal.

I can't, because this is no local development. We receive this via our error tracking from live client browsers. Actually we would like to have such errors on developer machines, and we try to unmask them to make them reproducible locally.

I've tried to use @arcgis/[email protected] and got this error:

WARNING in ../../node_modules/@arcgis/core/core/workers/workers.js 5:863-872
Critical dependency: the request of a dependency is an expression

As it seemes through the code, arcgis/core uses dynamic imports with variable. Is it possible to consume arcgis/core by webpack alone or do I need some special plugin to assist?

[odoe]

That webpack warning can be ignored, it has no impact on build tooling. You can turn them off in webpack here.

There is no special plugin needed for @arcgis/core, but this is outside the scope of this repo.

@odoe thank you for answer.

but this is outside the scope of this repo

Understood. I expected it to be so. Where is the better place to address arcgis/core related questions?

[andygup]

Closing as won't fix.
