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

The sourceFile read-only property of the InterventionReportBody interface returns the path to the source file where the intervention occurred.

Note: This property can be used with InterventionReportBody.lineNumber and InterventionReportBody.columnNumber to locate the column and line in the file where the feature is used.


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


In this example we create a new ReportingObserver to observe intervention reports, then print the value of sourceFile to the console.

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

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