The ReportingObserverOptions dictionary of the Reporting API allows options to be set in the constructor when creating a ReportingObserver.


An array of strings representing the types of report to be collected by this observer. Available types include deprecation, intervention, and crash.
A boolean that defines whether the reports that were generated before the observer was able to be created should be observable (true) or not (false).


let options = {
  types: ['deprecation'],
  buffered: true

let observer = new ReportingObserver(function(reports, observer) {
  reportBtn.onclick = () => displayReports(reports);
}, options);
