node-hook

Run source transform function on Node require

npm install --save node-hook

Before loading desired .js files, install hook

var hook = require('node-hook');
 
function logLoadedFilename(sourcefilename) {
    return 'console.log("' + filename + '");\n' + source;
}
hook.hook('.js', logLoadedFilename);
require('./dummy');
// prints fulle dummy.js filename, runs dummy.js 
 
hook.unhook('.js'); // removes your own transform 

remember: Nodejs caches compiled modules, so if the transform is not working, you might need to delete the cached entry in require.cache, then call require(filename) again to force reload.

You can hook several transformers thanks to the code submitted by djulien
