Specificationhttps://github.com/w3c/ServiceWorker Other changes: https://github.com/w3c/resource-timing/pull/415 https://github.com/whatwg/fetch/pull/1832 Summary Adds timing information for ServiceWorker Static routing API, exposed in navigation timing API and resource timing API for developer use. Service Worker provides timing information to mark certain points in time. We add two Static routing API-relevant timing information: RouterEvaluationStart, time to start matching a request with registered router rules, and CacheLookupStart, time to start looking up the cache storage if the source is "cache". In addition, we also add two router source information, the matched router source and the final router source.

Non-OSS dependencies Does the feature depend on any code or APIs outside the Chromium open source repository and its open-source dependencies to function? n/a Estimated milestones Shipping on desktop 140 Origin trial desktop first 131 Origin trial desktop last 136 Origin trial extension 1 end milestone 139 Shipping on Android 140 Origin trial Android first 131 Origin trial Android last 136 Origin trial WebView first 131 Origin trial WebView last 136 Anticipated spec changes Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way). We are making changes to the following specs: - Service Worker Spec https://github.com/w3c/ServiceWorker/pull/1769 has already been merged - Resource timing spec https://github.com/w3c/resource-timing/pull/415 has been reviewed, and are waiting for merge (waiting for the fetch-spec changes to be reviewed) - Fetch Spec https://github.com/whatwg/fetch/pull/1832 has been reviewed, but are still waiting for editor's review and are also waiting for other vendor's signal.
