If you are a pedant like me, and you want to prevent a new-line character from displaying onto the console, then you can use,


Instead of console.log.

If you are using 'use strict' (which you should be) then use "\x07" instead of "\007"

If anyone else comes by confused by process.stderr.on("\007"); it should be process.stderr.write("\007"); instead.

No sounds with any of the following on macOS High Sierra, node 8.10.0:

$ node --version
$ node
> console.log('\x07')
> console.log('\007')
> console.log('\u0007')
> process.stderr.write('\x07')
> process.stderr.write('\007')
> process.stderr.write('\u0007')

node-beep seems to be built only for windows.

@aneilbaboo You need to unfocus the terminal tab/window and make sure the "Audible bell" setting is enabled
in Preferences > Advanced

$ node
> setTimeout(() => console.log('\x07'), 1250)
// Unfocus the terminal before the timeout expires.
