Is there a way to detect that a web-worker has been loaded. I looked at the spec but there is only an error
event. There is no onload
, onreade
, onstatechange
or anything of the sort.
I am looking for an alternative to thescript element onload event but for web-workers.
I want to do it without the worker explicitly sending a message after load because it is for a library, and I need it to be as general as possible and don't want to impose this restriction on the worker.
There is not by design. This was planned originally , but got taken out later on. I forgot the rationale, but I suspect it is related to certain implementations allowing the allocation of many workers, but only running a couple at the time.
(There are some plans to improve this, in particular if SharedArrayBuffer
happens, which needs that kind of information, but there's no standard way now.)
A workaround might be to fetch the code in advance and then initiate the worker from a blob URL.
