DeprecationReportBody: sourceFile property

{{APIRef("Reporting API")}}{{AvailableInWorkers}}{{SeeCompatTable}}

The sourceFile read-only property of the {{domxref("DeprecationReportBody")}} interface returns the path to the source file where the deprecated feature was used.

[!NOTE] This property can be used with {{domxref("DeprecationReportBody.lineNumber")}} and {{domxref("DeprecationReportBody.columnNumber")}} to locate the column and line in the file where the error occurred.

Value

A string, or null if the path is not known.

Examples

In this example we create a new {{domxref("ReportingObserver")}} to observe deprecation reports, then print the value of sourceFile to the console.

let options = {
  types: ["deprecation"],
  buffered: true,
};

let observer = new ReportingObserver((reports, observer) => {
  let firstReport = reports[0];
  console.log(firstReport.type); // deprecation
  console.log(firstReport.body.sourceFile);
}, options);
