How would I require() a file if I had the file's contents as a string in memory, without writing it out to disk? Here's an example:
// Load the file as a string var strFileContents = fs.readFileSync( "./myUnalteredModule.js", 'utf8' ); // Do some stuff to the files contents strFileContents[532] = '6'; // Load it as a node module (how would I do this?) var loadedModule = require( doMagic(strFileContents) );

From the node. js documentation: Modules are cached after the first time they are loaded.
function requireFromString(src, filename) { var Module = module.constructor; var m = new Module(); m._compile(src, filename); return m.exports; } console.log(requireFromString('module.exports = { test: 1}', '')); look at _compile, _extensions and _load in module.js
