[Question] Is it possible to replace fastCloneDeep JSON.stringify(JSON.parse with structuredClone() ?

[kievsash]

Hi REASON to ask: I am implementing custom angular file-select component and want File object to be accessible as formfield value on formSubmit. But when I do valueChanges.emit({file: someFileObjWithBlob}) inside custom element then on submit event I get empty object (btw customEvent transfer File obj correctly)

After small ivestigation I suspect that maybe it is because in submit event handler we sometimes do copy with fastCloneDeep Util function which is just JSON.parse(JSON.stringify(obj)) So maybe it make sense to replace it with structuredClone? structuredClone does File structure copy correctly.

What do you think?

Yes, please submit a pull request with this change and we would be happy to merge it. Another alternative is that we are releasing a new "slim" angular module called "@formio/angular/embed". This may be another good option since we will be officially releasing that soon.
