Anything else we need to know

This proposal creates a native web API to match URLs called URLPattern. URLPattern would support both web developer use in JS and native URL matching in other web APIs. For example, the initial use cases discuss using URLPattern for service worker scope matching.

FYI, we are making a small enhancement to URLPattern to add the option to perform case-insensitive matching. This was a web developer community request. Please see:

Note, since this is a small change I thought it might be better to comment here instead of creating a new issue. If you would prefer a new issue, please let me know.

Thanks @wanderview, that seems fine. If you have the time, what is the latest on getting this more formally standardized as well as fixing some of the remaining issues?

[wanderview]

If you mean moving urlpattern into whatwg, that is still something I would like to do but is a lower priority at the moment. If another browser indicates they want to start implementing it would raise the priority of doing that work.

I'm going to mark this as blocked. We'd be supportive of this if it was maintained and the venue issue was resolved. Additionally if-and-when we should carefully look at the CSP use cases around matching and ensure there's parity.

[annevk]

After having discussed this at the most recent W3C TPAC, the maintenance issue and venue question have been resolved. As mentioned above I suggest we mark this as "position: support" one week from now therefore.

Just as an fyi the spec is now published at https://urlpattern.spec.whatwg.org/
