Specification There's no spec or draft spec for the per-function part yet - getting feedback on the input format is one of the goals of the Origin Trial. Summary Allow attaching information about which functions should be eager parsed & compiled in JavaScript files. The information will be encoded as magic comments. This is an extension of the Per-File Explicit Compile Hints feature ( https://chromestatus.com/feature/5100466238652416 ), where we now allow marking individual functions for eager parsing & compilation. Blink component Blink>JavaScript TAG review None TAG review status Pending Risks Interoperability and Compatibility None Gecko: N/A (https://github.com/mozilla/standards-positions/issues/780) This is a position request for the previous iteration of compile hints; the per-file version. We expect their views about this extension to be similar. WebKit: N/A (https://github.com/WebKit/standards-positions/issues/172) This is a position request for the previous iteration of compile hints; the per-file version. We expect their views about this extension to be similar. Web developers: Positive - Microsoft is interested in prototyping; needs the Origin Trial for evaluating performance in the wild - General positive sentiment, e.g., TC39 tooling meeting 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? None Goals for experimentation - Evaluate the performance improvement potential for real world web apps - Get feedback about the input format Ongoing technical constraints None Debuggability None Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? No Is this feature fully tested by web-platform-tests? No Flag name on about://flags None Finch feature name None Non-finch justification Web developers need to enable this feature on their side; adding a Finch flag as an additional gate doesn't make sense. Requires code in //chrome? False Estimated milestones No milestones specified (Will need to wait for partners to be ready to start the Origin Trial) Link to entry on the Chrome Platform Status https://chromestatus.com/feature/5153430045458432?gate=6215402451107840 This intent message was generated by Chrome Platform Status. -- Google Germany GmbH Erika-Mann-Straße 33 80636 München Geschäftsführer: Paul Manicle, Liana Sebastian.
