Execute a PM2 Command With Node.js

Question

I'd like to execute pm2 restart IDOFMYAPP using NodeJS... Is that possible?

Something like that :

var sys = require('sys')
var exec = require('child_process').exec;
function puts(error, stdout, stderr) { sys.puts(stdout) }
exec("pm2 restart IDOFMYAPP", puts);

Actually, I want to create a button to execute this code above but my button is in a view in my app that I want to restart...

EDIT #2

var shell = require('shelljs');

shell.exec('pm2 restart IDOFMYAPP', function(code, output) {
  console.log('Exit code:', code);
  console.log('Program output:', output);
  res.redirect('/');
});

You can do it like so:

var shell = require('shelljs');

shell.exec('pm2 restart IDOFMYAPP', function(code, output) {
  console.log('Exit code:', code);
  console.log('Program output:', output);
});

EADDRINUSE means that you have another service running on the same port.

Ok, so it works now, but how to redirect to '/' after success exec??

Can you elaborate on that? It sounds like creating another question might be more appropriate.

See edit#2 above... Because your code works but my web page seems to not appreciate the pm2 restart IDOFMYAPP...
