Trying to figure out a way to load directories through webpack programmatically

gistfile1.js

module.exports = function(folder, regex) {
  if (folder == null) {
    folder = './';
  }

  if (regex == null) {
    regex = /\.(js|json|jsx)$/;
  }

  var req = require.context(folder, false, regex);

  return req.keys().reduce(function(obj, name) {
    obj[name] = req(name);
    return obj;
  }, {});
};
