javascript / node: load / require a directory of modules and bind arguments to each returning a single object with all the methods. This is useful for example if you'd like to bind a series of utility methods to the same database object.

loadDirAndBind.js

var fmt = require('util').format;
var join = require('path').join;

module.exports = function loadAndBind(path) {
  var methods = {};
  var normalizedPath = join(__dirname, path);
  var args = [].slice.call(arguments, 1);

  require("fs").readdirSync(normalizedPath).forEach(function(file) {
    var mod = require(join(normalizedPath, file));
    if (methods[mod.name]) {
      throw fmt("Existing method with name %s", mod.name);
    }
    methods[mod.name] = mod.bind.apply(mod, [].concat(mod, args));
  });

  return methods;
};
