SharedWorkerGlobalScope: close() method
Baseline
2026
Newly available
Since May 2026, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
The close() method of the SharedWorkerGlobalScope interface discards any tasks queued in the SharedWorkerGlobalScope's event loop, effectively closing this particular scope.
Syntax
js
close()
Parameters
None.
Return value
None (undefined).
Examples
If you want to close your worker instance from inside the worker itself, you can call the following:
js
close();
close() and self.close() are effectively equivalent — both represent close() being called from inside the worker's inner scope.
Note:
There is also a way to stop the worker from the main thread: the Worker.terminate method.
