new Worker(browser.runtime.getURL('source/worker.js'))
throws an error:
Error: This script should only be loaded in a browser extension.
I have a hefty background processing operation that I need to pass off to a web worker, but the script I try to execute causes this error.
Is there a standard way of spawning a web worker in a background script for a safari web extension?

I am currently developing a safari web extension on iOS.
The following piece of code is executed in the native application when the extension sends a message to the native app using browser.runtime.sendNativeMessage.
func beginRequest(with context: NSExtensionContext) {
let item = context.inputItems[0] as! NSExtensionItem
let message = item.userInfo?[SFExtensionMessageKey]
os_log(.default, "Received message from browser.runtime.sendNativeMessage: %@", message as! CVarArg)
// Message should follow format of:
// {
// type: "Message type",
// payload: "Message Payload"
// }
// In the future we may want to parse the payload differently, but for now it is a string
guard let response = message as? [String : AnyObject] else {
return
}
guard let type = response["type"] as? String else {
return
}
guard let payload = response["payload"] as? String else {
return
}
let res = NSExtensionItem()
if type == "COPY" {
let itemToCopy = [payload]
let pasteboard = UIPasteboard.general
pasteboard.strings = itemToCopy
res.userInfo = [ SFExtensionMessageKey: [ "res": true ] ]
}
context.completeRequest(returningItems: [res], completionHandler: nil)
The code works flawlessly in the iOS 15 simulator, however it does not work on the actual device. ( iPod Touch 7th Generation running iOS 15 beta 2 )
There are no errors, it behaves as if it was working as expected.
Any help would be greatly appreciated.
I have a Safari web extension that needs the ability to open the popup when the user interacts with a modal coming from the content script.
There is a native message handler that comes with the safari web extension when you first create it:
import SafariServices
import os.log
class SafariWebExtensionHandler: NSObject, NSExtensionRequestHandling {
func beginRequest(with context: NSExtensionContext) {
let item = context.inputItems[0] as! NSExtensionItem
let message = item.userInfo?[SFExtensionMessageKey]
os_log(.default, "Received message from browser.runtime.sendNativeMessage: %@", message as! CVarArg)
let response = NSExtensionItem()
response.userInfo = [ SFExtensionMessageKey: [ "Response to": message ] ]
print("hit")
context.completeRequest(returningItems: [response], completionHandler: nil)
}
}
I have the permissions to send a native message, I've seen some examples online where you can access the SFSafariApplication module from SafariServices and open the popover. But I can't seem to access SFSafariApplication in this module.
