*Specification* *Not yet.* *Summary* Expose measurement data regarding speculative loads (preloads, prefetch and prerenders) as part of the "pagehide" event. That would enable developers to measure the efficacy of various speculative loading strategies and adapt them accordingly. *Blink component* Blink>PerformanceAPIs <https://issues.chromium.org/issues?q=customfield1222907:%22Blink%3EPerformanceAPIs%22> *Web Feature ID* Missing feature *TAG review* *Not yet.* *TAG review status* Not yet filed. *Goals for experimentation* See that the API shape enables developers to solve real life measurement issues related to speculative loads. *Risks* *Interoperability and Compatibility* *As a new API surface, there are no real compatibility issues.* *As far as interoperability goes, it's a bit early to tell. We haven't asked for positions just yet.* *Gecko*: No signal yet. *WebKit*: No signal yet. *Web developers*: Support from Wix <https://github.com/WICG/proposals/issues/264#issuecomment-3904289446> and general support at WebPerfWG discussions. *Other signals*: *WebView application risks* Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications? *No* *Ongoing technical constraints* *No* *Debuggability* *Nothing in particular.* *Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)?* Yes *Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>?* Yes *Flag name on about://flags* *No information provided* *Finch feature name* *SpeculationMeasurement* *Non-finch justification* *None* *Requires code in //chrome?* False *Tracking bug* https://issues.chromium.org/issues/481590676 *Estimated milestones* M150-M155 inclusive *Link to entry on the Chrome Platform Status* https://chromestatus.com/feature/5118840377835520?gate=6004022601449472 *Links to previous Intent discussions* Intent to Prototype: https://groups.google.com/a/chromium.org/d/msgid/blink-dev/CAOmohSJA9q57gnHFyJ1WqUUJi2AX5UCmtDM50URp9hjx3J4WJg%40mail.gmail.com This intent message was generated by Chrome Platform Status <https://chromestatus.com/>. -- You received this message because you are subscribed to the Google Groups "blink-dev" group.
