DeprecationReportBody.columnNumber

The columnNumber read-only property of the DeprecationReportBody interface returns the line in the source file in which the deprecated feature was used.

Note: This property is most useful alongside DeprecationReportBody.sourceFile and DeprecationReportBody.lineNumber as it enables the location of the column in that file and line where the error occurred.

Syntax

let columnNumber = DeprecationReportBody.columnNumber;

Value

An integer, or null if the column is not known.

Examples

In this example we create a new ReportingObserver to observe deprecation reports, then print the value of columnNumber 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); // the source file
  console.log(firstReport.body.lineNumber); // the line in that file
  console.log(firstReport.body.columnNumber); // the column in that file.
}, options);
