Know your code health with the ReportingObserver API | Capabilities | Chrome for Developers

const observer = new ReportingObserver((reports, observer) => { for (const report of reports) { console.log(report.type, report.url, report.body); } }, {buffered: true}); observer.observe(); Use the callback to send reports to a backend or analytics provider for analysis. Why is that useful? Until this API, deprecation and intervention warnings were only available in DevTools as Console messages.
