从内存中的字符串加载node.js模块

Question

如果我将文件的内容作为字符串存储在内存中而不将其写出到磁盘，该如何请求文件？这是一个例子：

// 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) );

Answer 1

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}'));

在module.js中查看_compile，_extensions和_load
