Hi,
is there a way to get the event 'SIGINT' fired on ctrl-c pressed in debug mode?
It seem that the event is correctly fired without debug, but not in debug mode.

thanks in advance

Can you clarify what you mean by 'debug mode' and post steps to reproduce?

Hi @bnoordhuis
I have this code in my index.js:

 process.on('SIGINT', function (){
     console.log('Hello');
 });

If I run my app normally with

 node index.js

and then close it with CTRL+C, the 'Hello' message pops out as expected.

Instead, if I run my app in debug mode with

 node debug index.js

and then close it with CTRL+C, no message is shown!

Okay, I believe I understand what you mean. It's because the ^C is intercepted by the debugger, to break out of loops and such.

I understand. Unfortunately we have some important database consistency check attached to this event, is there a way to achieve the same result while using the debugger? Thanks in advance!

You can kill -INT <pid> from another terminal. Make sure you send it to the pid of the debuggee (the child process started by the debugger), not the debugger itself.

Thank you for this workaround! Sadly this can't be considered a real solution, any other idea?

[bnoordhuis]

You could attach a SIGTERM listener, that's the signal that the debugger sends when it terminates the debuggee.

I'll go ahead and close the issue.
