System Beep in Node.js

system-beep.js

function alertTerminal(){
  console.log("\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
v8.10.0
$ 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.

Thanks @aleclarson . I needed to unclick 'Silence bell' in my iTerm 2 profile under 'Notifications'

Is it possible to change the beep frequency and duration with nodejs? Some languages have something like: Beep(hertz, milli) (https://stackoverflow.com/questions/38883092/how-to-make-motherboard-beep-through-c-code)
Or
SoundBeep, Frequency, Duration
(AutoHotKey: https://www.autohotkey.com/docs/commands/SoundBeep.htm)

in git bash terminal
echo -e "\a"

@mayeaux Mine didn't work because I was running the code in VSCode terminal, after switching to main terminal it worked

windows or wsl

require("child_process").exec("powershell.exe [console]::beep(500,600)");

Mac

require("child_process").exec("afplay /System/Library/Sounds/Glass.aiff");

Yeah, for some reason in VScode terminal it doesn't sound, in main terminal it works. Thanks for the tip!

Thank you very much!
