constructor of the Reporting API creates a new ReportingObserver

js
new ReportingObserver(callback) new ReportingObserver(callback, options)
callback
A callback function that runs when the observer starts to collect reports (i.e. via ReportingObserver.observe()
). The callback function is given two parameters:
options
Optional
An object allowing you to set the options for creating the object. The available options are:
types
An array of strings representing the types of report to be collected by this observer. Available types include deprecation
, intervention
, and crash
(although this last type usually isn't retrievable via a ReportingObserver
). If this option is omitted, all supported types are collected.
buffered
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
).
js
const options = { types: ["deprecation"], buffered: true, }; const observer = new ReportingObserver((reports, observer) => { reportBtn.onclick = () => displayReports(reports); }, options);
