node.js - what's the best way to reference parent/containing nodejs module? -

mymodule   |__index.js   |__foo.js   |__bar.js       

inside of foo.js want reference mymodule (parent). what's best way of doing that?

i debating between 1 of following:

var parent = module.parent.exports var parent = require('./'); 

you can use __dirname reference parent module.
