DeprecationReportBody.sourceFile

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The sourceFile read-only property of the DeprecationReportBody interface returns the path to the source file where the deprecated feature was used.

Note: This property can be used with DeprecationReportBody.lineNumber and 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 ReportingObserver to observe deprecation reports, then print the value of sourceFile to the console.

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

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