The ReportBody interface of the Reporting API represents the body of a report. Individual report types inherit from this interface, adding specific attributes relevant to the particular report.

• CSPViolationReportBody
• DeprecationReportBody
• InterventionReportBody

An instance of ReportBody is returned as the value of Report.body. The interface has no constructor.

ReportBody.toJSON()

A serializer which returns a JSON representation of the ReportBody object.

In this example we create a new ReportingObserver to observe intervention reports. The InterventionReportBody interface inherits from ReportBody.

const options = {
  types: ["intervention"],
  buffered: true,
};

const observer = new ReportingObserver(([firstReport], observer) => {
  console.log(firstReport.type); // intervention
}, options);
