Detecting CTRL+C in Node.js

Question

I got this code from a different SO question, but node complained to use process.stdin.setRawMode instead of tty, so I changed it.

Before:

var tty =          


        

Answer 1

If you're trying to catch the interrupt signal SIGINT, you don't need to read from the keyboard. The process object of nodejs exposes an interrupt event:

process.on('SIGINT', function() {
    console.log("Caught interrupt signal");

    if (i_should_exit)
        process.exit();
});

Edit: doesn't work on Windows without a workaround. See here

Answer 2

For those who need the functionality, I found death (npm nodule, hah!).

Author also claims it works on windows:

It's only been tested on POSIX compatible systems. Here's a nice discussion on Windows signals, apparently, this has been fixed/mapped.

I can confirm CTRL+C works on win32 (yes, I am surprised).
