How I trigger the "System Bell" in nodejs

Question

I'm running a long running custom nodejs script and would like to be notified when the script is completed.

How do I make nodejs trigger the "System Bell"?

The same way as with anything else you run in a console window: output the BEL character (ASCII 7) to the standard output. — Karl Knechtel, Dec 19 '11 at 05:57
@wulong, That worked great, thanks! You should post this as an answer. — Brad, May 14 '12 at 00:29

Output the BELL character (Unicode 0007) to the standard output.

console.log('\u0007');

It works in terminal, but not in terminal inside vscode. – Codler May 25 '20 at 09:35

The console.log('\u0007') didn't work for me running VSCode on windows 10. The following code did work:

import { exec } from 'child_process'
exec(`rundll32 user32.dll,MessageBeep`)

even if the `console.log` version worked for me, it did not work after building an electron app with the code. Your solution also works for electron apps on windows 10. – messerbill Dec 07 '20 at 20:13
one more case, use `>` redirect console output to a file – benbai123 Jul 01 '21 at 12:30
