Listening for Changes

To listen for data range changes use addListener.

// create a default workbook
const workbook:IWorkbook = new Workbook();
// get a range that can be iterators or allow for updates

const removeListener:RemoveListener = workbook.getRange('Sheet1!A1:E5000').addListener((event: WorkbookRangeEvent): void => {
  // do something with the range. We are justing going to log it.
  console.log(`We received an event from ${event.getSource().toString()}`);
});
// call removeListener() to remove the listener when finished
