Specificationhttps://wicg.github.io/soft-navigations Summary Exposes the (experimental) soft navigation heuristics [1] to web developers, using both PerformanceObserver and the performance timeline.

None Goals for experimentation Reason this experiment is being extended We are still collecting feedback from partners, who are evaluating the suitability of this API to replace existing ad-hoc methods of measuring soft navigations, including some who were only recently able to start experimenting. Additionally, we have made changes to the heuristics, in response to testing and feedback, to eliminate some false-positive detections, and better match the behaviour of real-world single-page apps. Some of these changes initially went out in Chrome 120, and were refined in Chrome 121; some will be released with Chrome 122. We'd like to give developers a chance to experiment with these changes, to help inform any future adjustments that need to be made. After Chrome 123, we intend to pause the experiment while we act on all of the feedback, and decide whether further changes to the heuristics are necessary, or if the API is in good enough shape to consider shipping. Ongoing technical constraints None.
