Override the require function

Is it possible to override the global require function, affecting it at process level?

From what I know, the require function is provided as argument in the function that wraps the NodeJS scripts:

(function (..., require, __dirname) { // something like this

   // The wrapped code

})(...);

Is there any way to modify the require function?

(function () {

    var _require = require;

    require = function () {

        console.log(...);

        _require.apply(this, arguments);

    };

})();

This will probably affect only the script where it's located.

How can we modify it at the process level?

var Module = require('module');

var originalRequire = Module.prototype.require;



Module.prototype.require = function(){

  //do your thing here

  return originalRequire.apply(this, arguments);

};
