Shared workers #39

Open jakearchibald opened 3 years ago

jakearchibald commented 3 years ago

Can a module block be used to instantiate a shared worker?

const module = module { export default 42; }
cons myWorker = new SharedWorker(module, { type: 'module' });

My gut feeling is 'no', since the only way two pages could share a shared worker is by sharing the module via postMessage. That also means that two origins could end up sharing the same worker which is new and terrifying 😄.

Yeah, I don’t think that will work, as every Module Block is unique. So it would effectively always refer to a different module.

I would love for this to be a thing. If the normal Worker would get this special treatment and SharedWorker would not, then I think the SharedWorker would be deprecated very soon: As it stands now, even though they are not too different the SharedWorker browser adaptation is tragic compared to the normal one.

What about ServiceWorker?

May I ask, do you oppose the idea, or do you just don't think is too complicated?

I think that the https://github.com/tc39/proposal-js-module-blocks/issues/45 is a possible solution to this.
