yorequire

You can use Your Own 'require' function.
If you want to hook the 'require' function, you can use yorequire.

Getting Started

Install the module with: npm install yorequire --save

var yorequire = require('yorequire');
yorequire.set(function(name, o_require, data) {
  // you can do anything you like.
  // 'name' is the module name which have requested.
  // 'o_require' is original require function. 
  // 'data' argument is the data that have passed to yorequire.set() as second argument.
  return o_require(name);
}, yourdata);
// calling 'set' function enables inner flag by default, so you do not have to call enable(true);
yorequire.enable(true);
