Description Olli Pettay 2015-04-17 10:44:57 UTC 
Seems like engines don't support SharedWorkers in Workers, so perhaps the spec should be updated to match the reality?
Or are there plans to support SharedWorkers in Workers?
Comment 1 Travis Leithead [MSFT] 2015-04-17 23:56:32 UTC 
Is there a technical reason engines haven't done this? I didn't think all engines had implemented Workers in Workers either...
Comment 2 Simon Pieters 2015-04-20 11:33:05 UTC 
FWIW Presto has supported arbitrary nesting of workers and shared workers since we introduced workers.
Comment 3 Ian 'Hixie' Hickson 2015-04-20 21:02:15 UTC 
SharedWorkers in Workers are pretty critical for the long-term usefulness of workers, IMHO...
Comment 4 Jake Archibald 2015-06-09 09:43:45 UTC 
SharedWorkers in ServiceWorkers is a feature request from https://github.com/slightlyoff/ServiceWorker/issues/678 too.

Additionally, we've had feature requests for being able to generate notification icons within a serviceworker. This requires workercanvas of course, but any pixel work should be farmed off to a worker so it doesn't block fetch (and other) events.

Could SharedWorker be tied to the life of the parent context, rather than specifically documents? (https://html.spec.whatwg.org/multipage/workers.html#dom-sharedworker) This would allow a sharedworker to be tied to the lifecycle of a serviceworker and/or documents.

Per comment 3. Jake's request is tracked by https://github.com/whatwg/html/issues/411.
