Excluding scopes from SW control

[Yoav Weiss (@Shopify)]

Hey folks!

I would like to put together a SW-related proposal and wasn't sure what's the best venue for that. I'd love your thoughts on this.

I have a use-case where I'd like to exclude certain paths from a SW scope, and ensure that any requests to document in those paths, or the subresources that they trigger will not be intercepted by a SW. In some ways, it's the inverse of the `Service-Worker-allowed` header.

What's the best venue to kick off such a proposal? Is that an issue/PR on the SW spec? somewhere else?

Cheers :)

Hi Yoav!

Thanks for reaching out.

I think your use case can be achieved by using the ServiceWorker Static Routing API. You can specify certain paths in a router condition, and set "network" as a router source. Then the request will bypass ServiceWorker interception if it matches the router condition. You can check more detail in https://github.com/WICG/service-worker-static-routing-api.

Let me know if you have any other questions!

Thanks Yoav for reaching out to us, and thanks Shunya for answering this.

I think people usually discuss the new ServiceWorker related proposals in the github issue (https://github.com/w3c/ServiceWorker/issues).

When you have a new proposal, please write it there.

For this case, as Shunya replied, I feel it is covered by the SW static routing API.  Moreover, as written in the explainer, it was our original motivation to bring the API.

However, as Shunya pointed out in person, people may also wonder if they can apply the rule to subsequent subresource loads when the main resource load matches the rule.

We disccuss that in https://github.com/WICG/service-worker-static-routing-api/issues/7.

Thanks!

I don't believe the static routing API fully covers the use case. I'll open an issue on the ServiceWorker spec to fully outline why :)

Cheers,
