Description
This API allows developers to configure the routing, and allows them to offload simple things ServiceWorkers do. If the condition matches, the navigation happens without starting ServiceWorkers or executing JavaScript, which allows web pages to avoid performance penalties due to ServiceWorker interceptions.
Starting ServiceWorkers is known to be a slow process, and web users need to wait for its startup if the ServiceWorker intercepts loading the page resources. At the same time, the ServiceWorker brings flexibility to the transport layer, and it behaves as a client-side proxy. Developers can implement offline support or provide client-side content modification with it. Currently, ServiceWorkers intercept all requests for pages within their scope, which brings a performance penalty within the scope.
Venue: we plan to do incubation work in the discussion tracker of w3c/ServiceWorker, despite hosting the explainer in a private repository.
In principle this idea seems reasonable, but this builds upon URLPattern (discussed in #61) which despite repeated requests hasn't been standardized.
@annevk Thank you for your help, I think the venue issue of URLPattern was resolved. Do you think this status can be updated as well?
URLPattern became the web standard, and it is actively maintained now.
Do you have any other concerns?
FYI, but the ServiceWorker static routing API has been merged to the spec. https://github.com/w3c/ServiceWorker/commit/8d4b9dfbeea511955a259949f2bc01227f995fe2
I discussed this with colleagues and this seems like a reasonable addition to us. Thanks for working on it!
As such I suggest we resolve this as "position: support" one week from now.
