Default SIGINT in Node.js?

Question

Default SIGINT in Node.js?

I tried searching the Node.js source code, but I could not find it. By default, where would I find the Node.js code that handles SIGINT (Ctrl-c) by default in the following example:

var http = require('http');

var server = http.createServer(function(req, res) {
  res.writeHead(200);
  res.end('Hello Http');
});


server.listen(5001);

node.js
sigint

Answer 1

Node's default SIGINT handler is in node.cc, but it doesn't do much. It calls signalExit, which does

uv_tty_reset_mode();
_exit(1);

You can add your own handler in node.js with

process.on('SIGINT', function () {
    // handle
});

Answer 2

You have to add it yourself. http://nodejs.org/api/process.html#process_signal_events

process.on('SIGINT', function () {
    //do stuff here.
});
