How Does The Path To Files Work?

I have installed npm and bcrypt successfully on my mac and printed out the hashed password. My question is about how it works behind the scenes. My app.js file is located totally in a different directory where bcrypt was installed (user/node_modules/bcrypt). I see on the bcrypt contents the 'package.json' file that points to the bcrypt folder, but in my app.js I give a path of only 'bcrypt' to the require method and not the path where the actual module resides. What is happening here? Why am I not giving a path of '../user/node_module/bcrypt' to the require method? How does JavaScript know where the module is located? Or is npm doing this work behind the scenes?
