In Node.js, how can a module get data from a package.json application?

I have a module. Inside this, I would like to access data from my parent package package.json. What is the best way to do this?

I did it in a janky way, going up 2 levels and requiring a file (or using the nconf configuration loader).

var appdir = path.resolve(__dirname, '../../');
nconf.file('app', path.join(appdir, 'package.json'));

But it looks like it could break easily.

I also heard about pkginfo , it automatically grabs information from my own package.json module, but I want to get data from the parent application.

Thanks for any help!

EDIT: I assume another way to ask the question is: how can I get the path to the program (instead of the path to the module)?

  var mainPath = attempts === 1 ? './' : Array(attempts).join("../");
  try {
    return require.main.require(mainPath + 'package.json');
  } catch (e) {
    return loadMainPackageJSON(attempts + 1);
  }
}

var packageJSON = loadMainPackageJSON();
