./a.js
require('./b_dir/b');
./b_dir/b.js
var fs = require('fs');
console.log(fs.readFileSync(__dirname + '/../a.js', 'utf-8'));
As I was saying, it's your problem to know where your required file is
located relative to the main file in your application. Or you could always
use some sort of global variable that tells you which is your app path. Or
even pass it to the required file. You have several options, but we still
don't know what problem you are trying to solve.
