*Summary*: Reporting API allows the page to receive notifications such as the usage of deprecated APIs and FeaturePolicy violations. I decided to implement this API, because it is required in the web-platform-tests for FeaturePolicy.
Reporting API covers 2 different features: a. reporting to the current page, via ReportingObserver b. reporting to a remote server, known via 'report-to' HTTP header. My implementation covers only the first aspect. However I also have patches for the second part, not in review yet. *Bug*: https://bugzilla.mozilla.org/show_bug.cgi?id=1492036 *Link to standard*: https://w3c.github.io/reporting/ *Platform coverage*: everywhere. *Estimated or target release*: unknown yet. *Preference behind which this will be implemented*: dom.reporting.enabled *Is this feature enabled by default in sandboxed iframes?* yes. The reports are per contexts. (but not for workers or worklets yet. See https://github.com/w3c/reporting/issues/131 *DevTools bug*: no supports for devtools. I don't think we need to do anything for devtools. *Do other browser engines implement this?* Chrome shipped it in 69: https://www.chromestatus.com/feature/4672626140119040 No other browsers. *web-platform-tests*: https://wpt.fyi/results/feature-policy/reporting?aligned&label=stable https://wpt.fyi/results/reporting?aligned&label=stable _______________________________________________ dev-platform mailing list dev-platform@lists.mozilla.org https://lists.mozilla.org/listinfo/dev-platform
