How to start a process in node.js that thinks its being run from the commandline

I'm running require('child_process').exec('npm install') as a child process in a node.js script, but I want it to retain console colors. I'm running in windows, but want this script to be portable (e.g. to linux). How do I start a process that think's it's being run from the console?

Note: I'd rather not have npm-specific answers, but an answer that allows me to trick any command.

You can do this by letting the child process inherit the master process' stdio streams. This means you need to user spawn rather than exec, and this what you'd do:

var spawn = require('child_process').spawn;
var child = spawn('npm', ['install'], {
  stdio: 'inherit'
});
